【应用】PPTC和TVS应用于RS-485接口过流和浪涌保护，有效防止电路损坏
目前RS-485接口在工业产品的数据通讯上应用比较广泛。在实际应用中，接口传输线通常暴露于户外，因此极易因为干扰、电压不稳、负载短路、安装接线错误、雷击等原因引入过电压、过电流等损坏接口电路。一旦过压引入，就会击穿损坏。在有强烈的浪涌能量出现时，甚至可以看到收发器爆裂，线路板焦糊的现象。
因此过流保护和浪涌保护在设计中是必须要考虑的。通常使用自恢复保险丝和TVS来保护电路。如下图所示，
当有过电流或雷击事件发生时，产生的过电流、过电压由A/B线引入，经过GDT、自恢复保险丝和，TVS到电路内部。GDT作为初级共模防护，通常GDT可以承受10KA(8x20us)浪涌冲击。之后残压已经大大降低到1KV以下，然后TVS管作为二级保护，充当共模/差模保护，使收发器的电压被钳制在12V以下，实现对收发器的过流和浪涌保护。
通常，对于4KV以下过电压，可以省去初级保护—GDT。单用TVS就能实现浪涌保护的要求。一般TVS可选用电安科技的TVSSMBJ6.5CA、SMCJ6.5CA，视浪涌能力而定。当RS485总线安装错误或与电力线搭接短路时。A/B线上的自恢复保险丝可以提供短路保护，及时切断回路，以防止进一步损坏电路。PTC选1206到2920之间的封装，电流100mA以下即可。

贴片SMB封装的TVS SMBJ78A成功应用于储能BMS浪涌防护上
华东某客户的工商储能BMS板的锂电模拟前端IC的VCC上，需要并1颗SMBJ封装的TVS，来做浪涌防护，此IC共可管理18串电池，IC的电源直接从电池回路上取电，每串电池的设计测试极限电压4.25V，考虑选择TVS的反向截止电压需要大于持续工作的最大电压，所以选了SMBJ78A的TVS。SMBJ78A属于电安SMBJ系列中的一款产品，SMBJ广泛用于电子产品的电源端和信号端的浪涌保护和静电保护上。
