路灯，已经成为家喻户晓的一种照明灯，属于高功率、低节能的照明灯，给人们生活带来了很多方便。因为它是直接与城市电网相接，所以供电一般为220V的交流电，在实际使用过程中，电网会因各种因素而造成一个瞬时的高压波动，以及在雷雨天气时，电源会遭受雷击的损坏，这些过压行为都会给路灯供电电源带来极大的破坏，因此，对路灯电源进行浪涌防护已经刻不容缓了。
硕凯电子推荐的20D561K,该器件采用的是插件封装，方便焊接，浪涌承受能力较强，通流量可达6.5KA，且留有一定的余量，低漏电流。对于AC220V电源输出口有较好的浪涌防护。
有较高的环境适应性，工作温度范围为﹣40℃~﹢85℃。
20D561K压敏电阻的特点：
最大工作电压VAC/VDC: 350V/460V
压敏电压(@V1mA): 504~616V
浪涌通流量(@8/20μS): 6500A
最大能量(@10/1000μS): 220J
20D561K压敏电阻的应用：
路灯电源
适配器
驱动电源
防雷器
家用电器
