汽车电子的安全性、耐用性一直是各大汽车制造商关心的问题，随着技术的不断发展，汽车车载电子系统的电路保护、功率控制、传感应用也得到了越来越多的关注，如图1所示。常见的解决方案包括增加电路保险丝保护、优化器件布局、更智能化的电路保护、电源断开控制、乘客感应系统、防侧翻功能以及稳定性控制等等。为了实现这些功能，汽车电子系统越来越多地使用功率半导体。

图1 汽车电路保护

现如今的汽车系统基本都包含有半导体器件，尤其是复杂的混合动力车及新能源汽车。因此，汽车的设计人员需要考虑如何设计汽车电路保护方案，才能保证车辆各系统在15~20年的使用寿命内正常工作。凭借亚纳秒级的响应时间和相当高的浪涌吸收能力，TVS二极管（即瞬态抑制二极管是一种非常高效的电路保护器件，被广泛应用于汽车电子的电路保护中。

图2 TVS二极管在汽车电子系统中的应用电路

如图2所示，在电路中，当TVS二极管受到高能量冲击时，TVS二极管能够快速由高阻抗变为低阻抗，从而吸收瞬间大电流，把电压箝制在预定数值，保护电路元器件免受损坏。对于汽车级应用，在选取TVS二极管解决方案时，本文推荐LITTELFUSE（力特）公司提供的解决方案，包括TPSMA6L系列、TPSMB系列、TPSMC系列、TPSMD以及TP6KE系列。其中，TPSMA6L系列是设计用来保护敏感电子设备免受负载突降的影响，以及其他变化所引起的瞬态电压波动影响，非常适用于高可靠性汽车应用。此外，SMA低配置封装（DO221-AC）和SMB封装具备相同电气性能，但其封装高度要低（1.1mm）。

值得一提的是，TPSMA6L系列能够在-65℃~150℃的环境温度下正常工作，峰值脉冲功耗600W（T_A=25℃，10x1000μs波形，每个端子安装在5.0x5.0mm铜焊盘上）。同时，符合汽车级AEC Q101标准，符合IEC 61000-4-2的ESD标准，并且符合IEC 61000-4-4的EFT标准，器件无卤素并且符合RoHS标准。此外，在高温焊接时需要注意端子处焊接温度为260°C/10秒。

与TPSMA6L系列解决方案相比，TPSMB系列、TPSMC系列、TPSMD以及TP6KE系列解决方案作为可替代方案，同样适用于保护敏感电子设备免受雷击影响，以及其他因素所引起的瞬态电压影响，它们的电气原理图如图3所示。更多的解决方案、技术资料、技术难题以及器件在线采购可在世强官网搜索获取。
