ROHM Launches 2-in-1 <span style='color:red'>SiC</span> Molded Module “DOT-247”
  ROHM has developed the "DOT-247," a 2-in-1 SiC molded module (SCZ40xxDTx, SCZ40xxKTx), ideal for industrial applications such as PV inverters, UPS systems, and semiconductor relays. The module retains the versatility of the widely adopted "TO-247" package while achieving high design flexibility and power density.  The DOT-247 features a combined structure consisting of two TO-247 packages. This design enables the use of large chips, which were structurally difficult to accommodate in the TO-247 package, and achieves low on-resistance through an unique internal structure. Additionally, through optimized package structure, thermal resistance has been reduced by approximately 15% and inductance by approximately 50% compared to the TO-247. This enables a power density 2.3 times higher than the TO-247 in a half-bridge configuration –achieving the same power conversion circuit in approximately half the volume.  The new products featuring the DOT-247 package are available in two topologies: half-bridge and common-source. Currently, two-level inverters are the mainstream in PV inverters, but there is growing demand for multi-level circuits such as three-level NPC, three-level T-NPC, and five-level ANPC to meet the need for higher voltages. In the switching sections of these circuits, topologies such as half-bridge and common-source are mixed –making custom products necessary in many cases when using conventional SiC modules.  To address this challenge, ROHM has developed each of these two topologies—the smallest building blocks of multi-level circuits—into a 2-in-1 module. This enables flexibility to support various configurations such as NPC circuits and DC-DC converters, while significantly reducing the number of components and mounting area, and achieving circuit miniaturization compared to discrete components.  Evaluation boards will also be made available progressively to facilitate evaluation during application design.

Terminology  Half-bridge/ Common-source  A basic configuration of a power conversion circuit consisting of two MOSFETs. In a half-bridge configuration, the MOSFETs are connected in series, one above the other, and the output is taken from the connection point. By switching the upper and lower MOSFETs alternately, the output voltage can be switched between positive and negative, making this configuration widely used as the basic structure for high-efficiency power conversion in inverters and motor drive circuits.  Common Source is a configuration where the source terminals of the two MOSFETs are connected, and the output is taken from each drain. By grouping the source terminals, the gate drive circuit can be simplified, making it suitable for applications such as multilevel inverters.  Types of NPC-type multi-level circuits  NPC (Neutral Point Clamped) is a multi-level circuit configuration that divides the output voltage into three levels (+, 0, and -) to reduce voltage stress on the switching devices. The "0V" state is created by the neutral point, which is the contact point located between the positive and negative voltages.  T-NPC (T-type NPC) replaces the diode used to stabilize the neutral point with switching devices such as MOSFETs, enabling more efficient operation. ANPC (Active NPC) actively controls the potential of the neutral point itself using a switch, achieving smoother output waveforms and high-precision power conversion. T-NPC and ANPC are suitable for applications requiring higher output and efficiency.  ePTO (electric Power Take-Off)  A system that uses the power from an electric vehicle's motor or battery to drive external work machinery or equipment (such as hydraulic pumps or compressors). This is an electrified version of the PTO (Power Take-Off) used in conventional engine vehicles, and its adoption is advancing in environmentally friendly commercial vehicles and work vehicles.

  ROHM and Schaeffler, a leading German automotive supplier, have started mass production of a new high-voltage inverter brick equipped with ROHM’s SiC (silicon carbide) MOSFET bare chips as part of their strategic partnership. The inverter brick is intended for a major Chinese car manufacturer.High voltage inverter brickSiC MOS Wafer  The Schaeffler inverter subassembly is the essential power device building block (brick) to control the electric drive via logic signals. This is where the high-frequency current pulses are produced that set the vehicle’s electric motor in motion. The performance characteristics of the inverter brick now being produced are impressive: Schaeffler increased the output of the brick by increasing the maximum possible battery voltage to much more than the usual 800 V – and with RMS currents of up to 650 A, which turn the sub-module into a compact power pack.  “Through our strategic approach of incorporating scalability and modularity into our e-mobility solutions – from individual components to a highly integrated electric axle – we developed the readily integrated inverter brick. Based on our generic platform development, it took us just one year to bring this optimal product for the popular X-in-1 architectures to volume production readiness,” says Thomas Stierle, CEO of the E-Mobility Division at Schaeffler.  Modularity and scalability as the key to easy integration  As a core component of an inverter, a brick has to meet strict requirements. The characteristics of the sub-module are indicative of the factors behind the current sales success and start of volume production: ROHM’s silicon carbide (SiC) power semiconductors enable the frame-mounted sub-module with high power density to be compact, efficient, and readily integrated into various inverters through its modular and scalable design. The sub-module incorporates the power module for pulse width modulation (PWM) of the current pulses, the DC link capacitor, a DC link and a cooler. Moreover, the brick has a DC boost function, thanks to which a vehicle with 800 V architecture can also be charged at a 400 V charging station at a charging speed of 800 V.  “We are glad about the launch of volume production for Schaeffler’s inverter brick with our 4th generation SiC MOSFET,” says Dr. Kazuhide Ino, Member of the Board and Managing Executive Officer at ROHM. “With our SiC technology we are making a substantial contribution to increasing the efficiency and performance of electric cars.

ROHM Develops New High Power Density <span style='color:red'>SiC</span> Power Modules Compact high heat dissipation design sets a new standard for OBCs
  ROHM has developed the new 4-in-1 and 6-in-1 SiC molded modules in the HSDIP20 package optimized for PFC and LLC converters in onboard chargers (OBC) for xEVs (electric vehicles). The lineup includes six models rated at 750V (BSTxxx1P4K01) and seven products rated at 1200V (BSTxxx2P4K01). All basic circuits required for power conversion in various high-power applications are integrated into a compact module package, reducing the design workload for manufacturers and enabling the miniaturization of power conversion circuits in OBCs and other applications.  In recent years, the rapid electrification of cars is driving efforts to achieve a decarbonized society. Electric vehicles are seeing higher battery voltages to extend the cruising range and improve charging speed, creating a demand for higher output from OBCs and DC-DC converters. At the same time, there is an increasing need in the market for greater miniaturization and lighter weight for these applications, requiring technological breakthroughs to improve power density - a key factor - while enhancing heat dissipation characteristics that could otherwise hinder progress. ROHM’s HSDIP20 package addresses these technical challenges that were previously becoming difficult to overcome with discrete configurations, contributing to both higher output and the downsizing of electric powertrains.  The HSDIP20 features an insulating substrate with excellent heat dissipation properties that suppresses the chip temperature rise even during high power operation. When comparing a typical OBC PFC circuit utilizing six discrete SiC MOSFETs with top-side heat dissipation to ROHM’s 6-in-1 module under the same conditions, the HSDIP20 package was verified to be approx. 38°C cooler (at 25W operation). This high heat dissipation performance supports high currents even in a compact package, achieving industry-leading power density more than three times higher than top-side cooled discretes and over 1.4 times that of similar DIP type modules. As a result, in the PFC circuit mentioned above, the HSDIP20 can reduce mounting area by approx. 52% compared to top-side cooled discrete configurations, greatly contributing to the miniaturization of power conversion circuits in applications such as OBCs.  Going forward, ROHM will continue to advance the development of SiC modules that balance miniaturization with high efficiency while also focusing on the development of automotive SiC IPMs that provide higher reliability in a smaller form factor.  Product Lineup  *1: Tc=25°C VGS=18V *2: Combines chips with different ON resistances  *3: Q1, Q4 pins *4: Q2, Q3, Q5, Q6 pins  Application Examples  Power conversion circuits like PFC and LLC converters are commonly used in the primary side circuits of industrial equipment, allowing the HSDIP20 to also contribute to the miniaturization of applications in both the industrial and consumer electronics fields.  ◇ Automotive systems  Onboard chargers, electric compressors and more.  ◇ Industrial equipment  EV charging stations, V2X systems, AC servos, server power supplies, PV inverters, power conditioners, etc.  Sales Information  Pricing: $100/unit (samples, excluding tax)  Availability: OEM quantities (April 2025)  Supporting Information  ROHM is committed to providing application-level support, including the use of in-house motor testing equipment. A variety of supporting materials are also offered such as simulations and thermal designs that enable quick evaluation and adoption of HSDIP20 products. Two evaluation kits are available as well, one for double-pulse testing and the other for 3-phase full bridge applications, enabling evaluation under close to actual circuit conditions.

At the same time, we have established an integrated production system throughout the manufacturing process, solidifying our position as a leading SiC supplier.  ・EcoSIC™ is a trademark or registered trademark of ROHM Co., Ltd.  Terminology  Power Factor Correction (PFC)  A circuit that enhances the power factor by shaping the waveform of input power in the power supply circuit. By using a PFC circuit, the input power is made closer to a sine wave (power factor = 1), improving power conversion efficiency. While PFC circuits typically rely on diode rectification, OBCs often employ active bridge rectification using MOSFETs or bridgeless PFC. This approach is favored because MOSFETs offer lower switching losses, and especially in high power PFCs, using SiC MOSFETs reduces heat generation and power losses.  LLC Converter  A type of resonant DC-DC converter known for its high efficiency with low noise power conversion. The name LLC comes from its basic configuration, which combines two inductors (L) and a capacitor (C) in the circuit. By forming a resonant circuit, switching losses are significantly reduced, making it ideal for applications requiring high efficiency, such as OBCs, power supplies for industrial equipment, and server power supplies.

ROHM’s New <span style='color:red'>SiC</span> Schottky Barrier Diodes for High Voltage xEV Systems: Featuring a Unique Package Design for Improved Insulation Resistance
  ROHM has developed surface mount SiC Schottky barrier diodes (SBDs) that improve insulation resistance by increasing the creepage distance between terminals. The initial lineup includes eight models - SCS2xxxNHR - for automotive applications such as onboard chargers (OBCs), with plans to deploy eight models - SCS2xxxN - for industrial equipment such as FA devices and PV inverters in December 2024.  The rapidly expanding xEV market is driving the demand for power semiconductors, among them SiC SBDs, that provide low heat generation along with high-speed switching and high-voltage capabilities in applications such as onboard chargers. Additionally, manufacturers increasingly rely on compact surface mount devices (SMDs) compatible with automated assembly equipment to boost manufacturing efficiency. Compact SMDs tend to typically feature smaller creepage distances, fact that makes high-voltage tracking prevention a critical design challenge.  As leading SiC supplier, ROHM has been working to develop high-performance SiC SBDs that offer breakdown voltages suitable for high-voltage applications with ease of mounting. Adopting an optimized package shape, it achieves a minimum creepage distance of 5.1mm, improving insulation performance when contrasted with standard products.  The new products utilize an original design that removes the center pin previously located at the bottom of the package, extending the creepage distance to a minimum of 5.1mm, approx. 1.3 times greater than standard products. This minimizes the possibility of tracking (creepage discharge) between terminals, eliminating the need for insulation treatment through resin potting when surface mounting the device on circuit boards in high voltage applications. Additionally, the devices can be mounted on the same land pattern as standard and conventional TO-263 package products, allowing an easy replacement on existing circuit boards.  Two voltage ratings are offered, 650V and 1200V, supporting 400V systems commonly used in xEVs as well as higher voltage systems expected to gain wider adoption in the future. The automotive-grade SCS2xxxNHR are AEC-Q101 qualified, ensuring they meet the high reliability standards this application sector demands.  Going forward, ROHM will continue to develop high-voltage SBDs using SiC, contributing to low energy consumption and high efficiency requirements in automotive and industrial equipment by providing optimal power devices that meet market needs.  Application Examples◇ Automotive applications: Onboard chargers (OBCs), DC-DC converters, etc.  ◇ Industrial Equipment: AC servo motors for industrial robots, PV inverters, power conditioners, uninterruptible power supplies (UPS), and more  Online Sales InformationAvailability: The SCS2xxxxNHR for automotive applications are available now.  The SCS2xxxN for industrial equipment are scheduled in December 2024.

TerminologyCreepage Distance  The shortest distance between two conductive elements (terminals) along the surface of the device package. In semiconductor design, insulation measures with such creepage and clearance distances must be taken to prevent electric shocks, leakage currents, and short-circuits in semiconductor products.  Tracking (Creepage Discharge)  A phenomenon where discharge occurs along the surface of the package (insulator) when high voltage is applied to the conductive terminals. This can create an unintended conductive path between patterns, potentially leading to dielectric breakdown of the device. Package miniaturization increases the risk of tracking by reducing creepage distance.  Resin Potting  The process of encapsulating the device body and the electrode connections between the device and circuit with resin, such as epoxy, to provide electrical insulation. This provides durability and weather resistance by protecting against water, dust, and other environmental conditions.  AEC-Q101 Automotive Reliability Standard  AEC stands for Automotive Electronics Council, a reliability standard for automotive electronic components established by major automotive manufacturers and US electronic component makers.

ROHM’s New TRCDRIVE pack™ with 2-in-1 <span style='color:red'>SiC</span> Molded Module: Significantly Reduces the Size of xEV Inverters
  ROHM has developed four models as part of the TRCDRIVE pack™ series with 2-in-1 SiC molded modules (two of 750V-rated: BSTxxxD08P4A1x4, two of 1,200V-rated: BSTxxxD12P4A1x1) optimized for xEV (electric vehicles) traction inverters. TRCDRIVE pack™ supports up to 300kW and features high power density and a unique terminal configuration - help solving the key challenges of traction inverters in terms of miniaturization, higher efficiency, and fewer person-hours.  As the electrification of cars rapidly advances towards achieving a decarbonized society, the development of electric powertrain systems that are more efficient, compact, and lightweight is currently progressing. However, for SiC power devices that are attracting attention as key components, achieving low loss in a small size has been a difficult challenge. ROHM solves these issues inside powertrains with its TRCDRIVE pack™.  A trademark brand for ROHM SiC molded type modules developed specifically for traction inverter drive applications, TRCDRIVE pack™ reduces size by utilizing a unique structure that maximizes heat dissipation area. On top, ROHM’s 4th Generation SiC MOSFETs with low ON resistance are built in - resulting in an industry-leading power density 1.5 times higher than that of general SiC molded modules while greatly contributing to the miniaturization of inverters for xEVs.  The modules are also equipped with control signal terminals using press fit pins enabling easy connection by simply pushing the gate driver board from the top, reducing installation time considerably. In addition, low inductance (5.7nH) is achieved by maximizing the current path and utilizing a two-layer bus-bar structure for the main wiring, contributing to lower losses during switching.  Despite developing modules, ROHM has established a mass production system similar to discrete products, making it possible to increase production capacity by 30 times compared to conventional SiC case-type modules. To obtain samples, please contact a sales representative or visit the contact page on ROHM’s website.  Product LineupTRCDRIVE pack™ is scheduled to be launched by March 2025 with a lineup of 12 models in different package sizes (Small / Large) and mounting patterns (TIM: heat dissipation sheet / Ag sinter). In addition, ROHM is developing a 6-in-1 product with built-in heat sink that is expected to facilitate rapid traction inverter design and model rollout tailored to a variety of design specifications.  ☆: Under Development  AQG 324 is a qualification standard for automotive power modules established by ECPE (European Center for Power Electronics).  European automakers are required to comply with this standard when considering adoption.  Application Examples・ Automotive traction inverters  Sales InformationAvailability: June 2024 (OEM quantities)  Pricing: $550/unit (samples, excluding tax)  Comprehensive Support      ROHM is committed to providing application-level support, including the use of in-house motor testing equipment.

For details, please contact a sales representative or visit the contact page on ROHM’s website.  EcoSiC™ BrandEcoSiC™ is a brand of devices that utilize silicon carbide (SiC), which is attracting attention in the power device field for performance that surpasses silicon (Si). ROHM independently develops technologies essential for the evolution of SiC, from wafer fabrication and production processes to packaging, and quality control methods. At the same time, we have established an integrated production system throughout the manufacturing process, solidifying our position as a leading SiC supplier.  TerminologyTraction Inverter  Traction motors in electric cars are driven by 3-phase AC power with a phase shift of 120°. Traction inverters convert direct current supplied from the battery into 3-phase alternating current.  2-in-1  To convert DC into 3-phase AC, one high-side and one low-side MOSFET are required per phase for switching. A 2-in-1 configuration combines both of these MOSFETs into a single module.
