【应用】Littelfuse车规级TVS用于汽车挡位执行器，击穿电压25.7~28.4V，工作温度可达150℃

时间： 2023-03-16 来源：世强

技术问答

汽车换挡器分为传统换挡器和电子换挡器两种。传统的换挡器是通过操作挡杆，依赖拉索来控制变速箱。当前，汽车呈智能化、电子化发展趋势，电子换挡器越来越成为主流。电子换挡器是通过CAN来传输换挡信号给变速箱执行单元，挡位执行器接收换挡信号来执行换挡操作。电子换挡器和挡位执行器配套使用，整车用量1：1。

图1 挡位执行器框图

在上述挡位执行器框图中可以看到，TVS（瞬态抑制二极管）常用于电源模块或者CAN通信模块，而本文正是基于电子换挡器实际项目需要，给客户推荐了LITTELFUSE 车规级TVS TPSMC27CA。该器件击穿电压25.7~28.4V，快速响应时间小于1ps，当其两级受到反向瞬态浪涌电压大于击穿电压时，TPSMC27CA可快速由高阻抗变为低阻抗，吸收浪涌功率，以保护电路。

图2 TVS工作原理图

littelfuse的车规级TVS TPSMC27CA通过了AEC-Q101认证，适用于汽车产品，而且不含卤素，符合RoHS标准。另外，挡位执行器应用于变速箱附近，在换挡期间会有瞬间的温升，因此要求挡位执行器所用物料均需满足高温要求，工作温度需要125℃，TPSMC27CA工作温度-65~150℃，非常适用于挡位执行器产品。

【产品】快速响应时间小于1nS、峰值脉冲功率最高7000W的车规级TVS二极管 | 视频

Littelfuse车规级TVS二极管，保护汽车电子包括消除可能对控制单元、影音娱乐系统、传感器、喷油嘴、阀门、电动机、12/24/42/48V动力系统和水解控制器等造成损坏的瞬态浪涌。让设计更安全，防护更可靠！

新产品发布时间 : 2021-05-29

汽车电源端口在做抛负载测试，一般会加TVS来做浪涌防护，想问下加或者不加这个TVS，对电路会有什么影响，不加这个TVS，电路是不是立马就会出现故障？

所谓抛负载，就是指交流发电机在产生充电电流时突然切断蓄电池和发电机之间的连接所产生的瞬态现象。仅切断负载，叫单抛；在切断负载的同时，又切断蓄电池，叫双抛。在汽车电气系统中，抛负载瞬态现象的电压非常高，电路防护措施倘若没有做到位的话，会影响车载电子设备的性能甚至导致不可逆转的损坏。故，对于汽车抛负载瞬态现象，早已有国内、国际标准提出了专门的测试标准，如汽车电子热门标准ISO 7637-2 综上，可以知道给车载电子设备加上TVS可以有效防止车载电子设备损坏，推荐力特满足 ISO7637-2 5a/5b 保护和 ISO16750 抛负载测试标准的车规级TVS：https://www.sekorm.com/doc/51381.html
