某客户设计的交流充电枪项目产品为AC220V供电，电源需通过雷击浪涌测试，需求三颗压敏电阻和一颗气体放电管完成线路。本文推荐硕凯电子推出的MOV压敏电阻 14D561K和气体放电管SC2E8-600ML，满足客户220V线路防护要求，且可以为客户提供EMC测试以及相关整改方案。

常见AC220V端口浪涌防护方案如下：

14D561K参数如下：

1、最大交流工作电压：350V

2、压敏电压：560（504~616）V

3、最小绝缘电阻（at 50V）：1GΩ

4、工作温度：-40℃至85℃，

SC2E8-600ML参数如下：

1、工作电压Vdc：600V

2、浪涌通流量（@8/20μS）：20kA

3、结电容Cp：<1.5pF

4、响应速度：<1ns

5、工作温度：-40℃至90℃

硕凯电子产品优势：

1. 硕凯600V气体放电管和350V TVS可以满足220V线路防护要求；

2. 硕凯原厂可以提供EMC测试以及相关整改方案；

3. 性价比高，交期短

综上所述，硕凯电子推出的MOV压敏电阻14D561K和气体放电管SC2E8-600ML非常适用于交流充电枪。

硕凯陶瓷气体放电管SC2E5-150LL在电流互感器二次侧过压防护的应用

采用陶瓷气体放电管作为电流互感器二次侧过电压保护器的电压采样器件,其优越性在实际的应用中已经得到验证。在实际的应用中,使用了陶瓷气体放电管的电流互感器二次侧过电压保护器能够有效地减少漏电空开跳闸和产品自身发热烧毁现象,对于电流互感器一次侧经常会出现的一些瞬态的电压尖峰现象,也能够有效的滤除,不会出现经常误动作的现象。

【选型】国产气体放电管pin-pin替代Brightking（君耀）2RL090M-6，成本至少降10%

为实现低成本高性能pin-pin替代BRIGHTKING（君耀）公司2RL090M-6气体放电管，推荐选用国产硕凯电子的SC2E5-90LSMD，两者电性参数基本一致，不过，国产硕凯电子的气体放电管SC2E5-90LSMD具有650V更低的最大脉冲击穿电压，响应时间更快，产品对的故障安全保护能力更强。同时，具有更小的封装体积（5.0mm x 5.0mm x 4.2mm），方形放置牢固，更容易上锡。
