ROHM Develops New High Power Density SiC 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.　　For more information, please contact AMEYA360 or visit the contact page on ROHM’s website.　　EcoSiC™ Brand　　EcoSiC™ is a brand of devices that utilize silicon carbide, which is attracting attention in the power device field for performance that surpasses silicon. ROHM independently develops technologies essential for the advancement 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.　　・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 Develops Class-Leading* Low ON-Resistance, High-Power MOSFETs for High-Performance Enterprise and AI Servers

　　ROHM has developed N-channel power MOSFETs featuring industry-leading* low ON-resistance and wide SOA capability. They are designed for power supplies inside high-performance enterprise and AI servers.　　The advancement of high-level data processing technologies and the acceleration of digital transformation have increased the demand for data center servers. At the same time, the number of servers equipped with advanced computing capabilities for AI processing is on the rise and is expected to continue to grow. These servers operate 24 hours a day, 7 days a week – ensuring continuous operation. As a result, conduction losses caused by the ON-resistance of multiple MOSFETs in the power block have a significant impact on system performance and energy efficiency. This becomes particularly evident in AC-DC conversion circuits, where conduction losses make up a substantial portion of total power loss – driving the need for low ON-resistance MOSFETs.　　Additionally, servers equipped with a standard hot-swap function, which allow for the replacement and maintenance of internal boards and storage devices while powered ON, experience a high inrush current during component exchanges. Therefore, to protect server components and MOSFETs from damage, a wide Safe Operating Area (SOA) tolerance is essential.　　To address these challenges, ROHM has developed its new DFN5060-8S package that supports the packaging of a larger die compared to conventional designs, resulting in a lineup of power MOSFETs that achieve industry-leading* low ON-resistance along with wide SOA capability. These new products significantly contribute to improving efficiency and enhancing reliability in server power circuits.　　The new lineup includes three products. The RS7E200BG (30V) is optimized for both secondary-side AC-DC conversion circuits and hot-swap controller (HSC) circuits in 12V power supplies used in high-performance enterprise servers. The RS7N200BH (80V) and RS7N160BH (80V) are ideal for secondary AC-DC conversion circuits in 48V AI server power supplies.　　All three models feature the newly developed DFN5060-8S package (5.0mm × 6.0mm). The package increases the internal die size area by approximately 65% compared to the conventional HSOP8 package (5.0mm × 6.0mm). As a result, the RS7E200BG (30V) and RS7N200BH (80V) achieve ON-resistances of 0.53mΩ and 1.7mΩ (at VGS = 10V), respectively – both of which rank among the best in the industry in the 5.0mm × 6.0mm class, significantly contributing to higher efficiency in server power circuits.　　Moreover, ROHM has optimized the internal clip design to enhance heat dissipation, further improving SOA tolerance, which contributes to ensuring application reliability. Notably, the RS7E200BG (30V) achieves an SOA tolerance of over 70A at a pulse width of 1ms and VDS = 12V, which is twice that of the conventional HSOP8 package MOSFETs under the same conditions, ensuring industry-leading SOA performance in a 5.0mm × 6.0mm footprint.　　Going forward, ROHM plans to gradually begin mass production of power MOSFETs compatible with hot-swap controller circuits for AI servers in 2025, continuing to expand its lineup that contributes to greater efficiency and reliability across a wide range of applications.　　Product Lineup　　EcoMOS™ Brand　　EcoMOS™ is ROHM's brand of silicon power MOSFETs designed for energy-efficient applications in the power device sector.　　Widely utilized in applications such as home appliances, industrial equipment, and automotive systems, EcoMOS™ provides a diverse lineup that enables product selection based on key parameters such as noise performance and switching characteristics to meet specific requirements.　　EcoMOS™ is a trademark or registered trademark of ROHM Co., Ltd.　　Application Examples　　・AC-DC conversion and HSC circuits for 12V high-performance enterprise server power supplies　　・AC-DC conversion circuits for 48V AI server power supplies　　・48V industrial equipment power supplies (i.e. fan motors)　　Terminology　　Low ON-Resistance (RDS(on))　　The resistance value between the Drain and Source of a MOSFET during operation. A smaller RDS(on) results in lower power loss during operation.　　SOA (Safe Operating Area) Tolerance　　The range of voltage and current within which a device can operate safely without damage. Exceeding this range can lead to thermal runaway or device failure, making SOA tolerance a critical factor, especially in applications prone to inrush current or overcurrent.　　Power MOSFET　　A type of MOSFET used for power conversion and switching applications. N-channel MOSFETs are the mainstream choice, as they become conductive when a positive voltage is applied to the gate relative to the source, offering lower ON-resistance and higher efficiency than P-channel variants. Due to their low loss and high-speed switching capabilities, power MOSFETs are widely used in power circuits, motor drive circuits, and inverters.　　Hot-Swap Controller (HSC)　　A specialized integrated circuit (IC) that enables hot-swap functionality, allowing components to be inserted or removed while the power supply system remains active. It plays a crucial role in managing inrush current that occurs during component insertion, protecting both the system and connected components from damage.　　Inrush Current　　A sudden surge of current that momentarily exceeds the rated value when an electronic device is powered ON. Proper control of this current reduces stress on power circuit components, helping to prevent device failure and stabilize the system.

ROHM leverages over 50 years of expertise in audio IC development to establish superior sound quality design technology, offering products such as high-fidelity sound processors and high-quality audio power ICs.　　ROHM’s latest product builds on the 1st generation MUS-IC™ BD34301EKV audio DAC chip, renowned for its sound quality and widely adopted in high-end models from various companies. The BD34302EKV inherits the core design concept behind ROHM’s DAC chip — natural flat sound — and, by adding the three elements of spatial reverberation, quietness, and dynamic range from the MUS-IC™ series to authentically reproduce the “texture” of musical instruments for an even more realistic audio experience.　　By incorporating a new algorithm for Data Weighted Averaging (DWA), the BD34302EKV achieves a THD+N characteristic of -117dB (THD: -127dB), a key performance indicator that enhances sound quality by achieving a sound quality that conveys a realistic sense of texture. At the same time, the signal-to-noise ratio (SNR) of 130dB provides noise performance befitting a flagship DAC chip, while a sampling frequency of up to 1,536kHz allows customers to fully leverage the high-precision calculations of their digital signal processors (DSPs).　　In monaural mode, which allocates one DAC chip per channel, ROHM’s proprietary HD (High Definition) monaural mode contributes to smoother, more natural sound. As part of the MUS-IC™ series, uncompromising craftsmanship has been applied down to the smallest details. Based on years of expertise in sound quality design, the optimal bonding wire material for each terminal of the BD34302EKV was selected to accurately convey the natural “texture” of musical instruments. These features help create the ideal sound sought by high-end audio manufacturers.　　MUS-IC™ — ROHM’s Highest Grade Audio ICs        Created by combining the “sound quality design technology” with ROHM’s company mission of “Quality First”, “vertically integrated production system”, and “contribution to the musical culture”, MUS-IC™ (official name: ROHM Musical Device “MUS-IC™”) is an audio device brand that represents the ultimate IC solutions developed by ROHM’s team of experienced and dedicated engineers.　　For more information, please visit ROHM’s Musical Device “MUS-IC™” web page.　　https://micro.rohm.com/en/mus-ic/　　*MUS-IC™ is a trademark or registered trademark of ROHM Co., Ltd.　　Terminology        High Resolution Audio Source　　High-resolution audio sources, often called "hi-res audio," typically use a sampling frequency of 96kHz or higher and a bit depth of 24 bits or more. In comparison, standard CD-quality audio is played back at a 44.1kHz sampling frequency with 16-bit depth. This means hi-res audio provides significantly more data resolution and dynamic range than standard CD-quality audio, resulting in superior sound quality.　　DWA (Data Weighted Averaging)　　Technology that improves audio characteristics by balancing mismatches between elements when operating multiple switching components for analog conversion.　　THD+N (Total Harmonic Distortion + Noise)　　A key performance metric for audio equipment that measures the ratio of harmonics to the fundamental wave. Indicates how accurately the waveform is reproduced — the smaller the value the more faithful the reproduction.　　HD (High Definition) Monaural Mode　　ROHM’s proprietary digital signal processing technology that improves bit (amplitude) resolution. This allows for improvements in numerical performance while enhancing sound quality to deliver smooth audio that reveals the texture of musical instruments.
