车载供电系统由于不同原因造成的过电压脉冲冲击，在最新的EMC和电源质量评定标准ISO7637-2和ISO-16750-2有详细的规定。其中抛负载测试是最严酷的测试标准，模拟正在运行的汽车交流发电机突然切断电池和负载的情况。抛负载比较复杂，有单抛、双抛之分，而且汽车电源系统也有12V汽油车和24V柴油车之分。本文旨在简要分析抛负载测试标准，并且讲解最常用的增加TVS的方法通过抛负载测试以及如何选择一款合适的TVS。

1、简析ISO7637-2测试标准，形象化描述何为抛负载：

ISO7637-2测试标准定义了多种过电压瞬时脉冲的模型，下图中列出了这些图形化模型。可以比较清晰地看出抛负载测试标准5a/5b的含义是什么，具体的实施和测试标准请参见ISO7637-2标准细节：

2、如何通过抛负载测试：

抛负载测试在行业内既可以归类为EMC测试，也有专家认为这属于电源质量的评判标准。基于这些这些原因，都可以通过增加功率TVS管来通过测试。下面就为大家讲解下如何使用选用一款适合的TVS通过抛负载测试的经验，使用力特公司专门针对汽车抛负载测试的SLD8S系列TVS管，希望可以帮到大家。

① 第一，最基本的要满足车规AEC-Q101，管子结温需要最低150℃（SLD8S系列为175℃）。

② 第二，需要满足ISO7637-2 5a/5b 和ISO16750抛负载测试标准，具体的可以从下图中看到标准规定了测试电压范围（12V汽油车系统和24V柴油机系统规定不一样），还有每个脉冲持续的时间，测试时要求1分钟内至少通过10次脉冲冲击。可以看到我们选用的SLD8S系列满足电压Us和脉冲时间Td的要求。只是注意的是冲击电压Us并不能覆盖标准的整个范围，但是87V和123V已经完全满足一般车厂的要求了。

③ 第三，选择适合的型号，SLD8S有很多子型号，每个后缀对应不同的保护电压。一般的，12V汽油车系统选择20V、22V或者24V的版本，24V柴油车系统选择30V、33V或36V版本。我们的系统是12V电压，考虑到电源并不干净，所以选择了24V电压的版本即型号为SLD8S24A。当然由于TVS管保护功率一定，选用24V版本能承受的电流就会比20V小，如果你需要更大的保护电流可以选择20V版本SLD8S20A。

④ 其他的，选择SLD8S系列的原因还有，他采用了SMTO-263贴片封装（兼容DO-

218AB封装），方便焊接和替换。

【经验】如何通过公式计算给出ISO7637-2和ISO16750-2 5a 5b过抛负载测试的TVS管参数选型

ISO16750-2相比ISO7637-2更为严格，在抛负载测试时，新的标准要求110分钟做10次测试，每两次间隔1分钟，而老的测试标准仅需要做一次抛负载测试，一般用TVS管做过抛负载测试，本文主要以SLD8S24A为例讨论通过计算公式给出如何选择合适的过抛负载TVS管。

【技术浅谈】TVS的选型计算你做对了吗?（续）

TVS的选型计算介绍。上一篇写的计算方法针对的是单次的浪涌，比如Surge test一般两次浪涌之间会有30~60 s的间隔时间，这意味着TVS有足够的时间去把吸收的浪涌能量给耗散掉，不会因为热累积而导致TVS温度过高而损坏。但是，现实中还有一些情况是会有重复浪涌的。

【应用】TVS SM712-02HTG应用于RS422通讯保护，容值低至75pF

RS422接口是采用差分方式传输数据，基于电平是±6V，AB的共模电压在±7V之间。当有浪涌冲击时，感应雷需在ns级的状态下进行吸收，故为了降低TVS容值对1.25Mhz频率信号真实度的影响，TVS的电容值选择尽量在pF级别。Littelfuse的SM712-02HTG为+12V/-7V TVS，钳位电压是专门针对RS422这类电平应用设计的电压，另外该TVS的容值低至75pF。
