TVS管是一种高效能的保护类型的器件，在应用时，当两端受到瞬态的高压冲击时，TVS管能在ns级别甚至ps级别的时间内将自身的特性从高阻转化为低阻态，转换过程吸收大电流从而将TVS管两端的电压钳制在TVS的耐压值上，保护了负载端电路免受瞬态高能量的冲击。原理如图1所示。

图1：TVS应用原理

5a,5b是ISO16750-2的浪涌条件，该条件是基于车载各种开关、电源系统和负载特性可能产生的浪涌冲击能量决定的。满足5a/5b抛负载测试证明了产品在浪涌能力的保护方面的可靠性。

目前在端口回路为12V的系统，测试电压在16V，故TVS需满足16V以上的电平，经参数计算评估SLD8D24A满足需求。

汽车12V系统的5a脉冲波形曲线：

5a冲击曲线的主要参数：

当曲线的Us=101V，R1=1Ω，td=400ms时

TVS（SLD8D24A）导通后承受的电流：
Ipp=【(Us+Ua)-Vbr】/（R1+Rd）=【（101V+12V）-26.7】/（1+0.07）=79.7A(远小于SLD8D24A的8.3ms对应的1000A)

对应的冲击能量：估算为1/2*I2*Rd*t=0.5X79.7AX79.7AX0.07ΩX400ms=88.9J（远小于Ifsm2*Rf*8.3ms=149.4J）

Vbr：TVS的反向击穿电压，SLD8S24A是26.7~29.5V。

Vc：TVS的最大钳位电压，SLD8S24A的是38.9V

Rd：TVS导通时的阻抗。Rd=(Vc-Vbr)/Ipp。关于SLD8S24A,代入参数计算Rd=（38.9V-26.7V）/180A=0.07Ω。

Rf：TVS的正向导通阻抗，Rf=Vf/100A=0.018Ω

Ifsm:8.3ms波形对应的瞬态冲击电流1000A

5a,5b的浪涌冲击下，采用SLD8S24A后的电压抑制效果为US*：

实测的效果示意如图2，在回路瞬态冲击先，SLD8S24A的电流会在有冲击曲线在几个A左右，TVS钳位的电平在38.9V以内。

【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。

【经验】简析汽车抛负载测试标准ISO7637-2和ISO-16750-2，如何选择一款TVS管帮助通过这两项测试

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。
