目前国产车BCM车身控制器过抛负载测试时，24V供电系统需要过7637-5a，主要是考虑商用车私自改装问题，而12V供电系统仅过7637-5b就行，在12V电源输入端口加入一款1500W SMC封装TVS管做过压防护即可，选择的最大反向工作电压一般以28V和30V居多；同时，应成本压力，一般对TVS管的车规级认证要求不高，不过工作温度范围需要满足-40℃~125℃。

应如上设计要求，可推荐选择LITTELFUSE（力特）1500W双向TVS管 SMCJ30CA，最大反向工作电压30V，最小击穿电压33.3V（MAX 36.8V），最大钳位电压48.4V，最大峰值脉冲电流31A，工作温度范围-65℃~150℃，相关电性参数参考如下图1所示。

图1：Littelfuse（力特）双向TVS管SMCJ30CA典型电性参数

推荐理由如下：

1、Littelfuse（力特）双向TVS管SMCJ30CA在国产车BCM车身控制器12V电源输入过压防护具有成熟的市场应用，产品性能得到可靠验证；

2、-65℃~150℃宽工作温度范围，可满足车载严苛高低温的使用条件；

3、世强平台常备库存，可提供良好的供货交期和支持快速样品服务。

pin-pin替代RUILON公司P6SMB18CA的600W双向TVS管，成本降低5%~10%

为实现低成本高性能pin-pin替代RUILON公司P6SMB18CA的600W双向TVS管，推荐选用littelfuse（力特）的P6SMB18CA，25.5V更低的最大钳位电压，具有更强的突波承受能力；具有1μA更低的最大反向漏电流，并通过IEC 61000-4-2 30kV接触放电和空气放电测试标准，同时具有-65℃更低的工作结温，可适用于更恶劣的低温环境下工作。

【应用】120VAC电路和240VAC电路中三端双向可控硅过压保护方案

为实现最大的可靠性，可对三端开关型晶闸管进行过电压保护。应根据应用设备的线路电压选择产品型号。一般而言，120VAC电路选用Littelfuse推出的瞬态抑制二极管P4KE250CA，而240VAC电路应选用瞬态抑制二极管P6KE510CA。

【方案】100KW双向储能优选器件方案

描述- 对业内100KW双向储能产品而言，主功率电路多采用了六管IGBT搭建的三相应用拓扑架构。因100KW双向储能选择主功率架构器件时，规格需求通常是1200V/600A（包含裕量），驱动开关频率一般在20kHz以内，考虑到体内二极管散热等因数，功率模块一般会选用三个半桥模块来搭建六管架构。

【选型】为RS232串口数据线（TxD、RxD、GND）通信选择合适的TVS管

RS232通信一般由三条数据线组成，即TxD、RxD和GND，为保证RS232串口数据通信免受ESD影响，一般需要在TxD与GND、RxD与GND间加入一颗TVS管做ESD防护设计，本文推荐选用高性能版littelfuse的双向TVS管SPHV15-01ETG-C，或者选择低成本版高特双向TVS管GSD15C，两者的最大反向工作电压均为15V，均为小尺寸贴片封装，均可满足设计需求。

【选型】为SD卡电源及数据线（CLK、CMD、DAT0~DAT3）通信选择一款合适的TVS管

车辆远程监终端GPRS模块上有用到SD卡，为保证SD卡数据通信免受ESD影响，需要对SD卡工作电压和数据线上均加入一款TVS管做ESD防护设计，本文推荐选用littelfuse的双向TVS管SP1233-01ETG，具有3.3V最大反向工作电压，0.5μA最大泄露电流，可安全吸收±30kV（接触放电，IEC 61000-4-2）时反复性ESD震击，而性能无任何降低。

USB接口和SIM卡接口防静电使用的ESD器件要求有不同吗？

基本上是没有不同的，SIM卡接口有四路，分别为VBUS、DATA、CLK、RESET，每路均需要做ESD防护，而USB接口中的USB1.1/USB2.0也是四路，分别为VBUS、D+、D-、GND，其中除GND外均需要做ESD防护，不过USB3.0接口在USB1.1/USB2.0原四路信号的基础上，有新增SSTX+/SSTX-、SSRX+/SSRX-，这四路高速信号均需要做ESD防护。且工作电压VBUS也兼容（5V），如果每路均选用一颗双向的TVS管，要求直接接触的ESD耐压大于±8KV即可，当然，可以选择1颗四路双向TVS阵列做ESD防护，或者2颗双路双向TVS阵列。针对SIM卡ESD防护设计做选型推荐如下，为littelfuse（力特）保护器件：USB1.1/USB2.0ESD防护设计推荐选型如下，为littelfuse（力特）保护器件：：USB3.0 ESD防护设计推荐选型如下，为littelfuse（力特）保护器件：：
