技术问答

如图1为新能源卡车油泵控制器的原理图框，通过控制三相电机（液压油泵）来实现电子助力，为卡车助力转向提供动力。

其中在控制器低压供电侧主要通过24V蓄电池供电，为igb驱动芯片、MCU等器件提供电源，但整车蓄电池后级负载有很多，在一些后级负载突降情况下，油泵控制器电压侧将有过高浪涌电压的出现，导致器件失效风险出现，故需要为油泵控制器添加合适的TVS管提供浪涌保护。

图1：新能源卡车油泵控制器的原理图框

如图2为在24V蓄电池电源端增加双向TVS管示意图，这里主要介绍硕凯车规双向TVS管SM8S36CA应用于卡车油泵控制器24v蓄电池端做防护优势特点：

图2：24V蓄电池电源端增加双向TVS管示意图

1、SM8S36CA为36V钳位电压的TVS管，在24v蓄电池供电端留有一定余量，保证控制器在正常工作时不频繁触发TVS管动作，在有过压出现时可以有效钳位，保护后级器件。

2、SM8S36CA峰值脉冲耗散功率为6600W（10/1000us），在触发钳位电压时，有效抵抗浪涌电流冲击，最高峰值浪涌电流达114A@VC=58.1v；

3、SM8S36CA具有双向钳制功能，可同时保护正、负极性的浪涌冲击；

4、通过AEC-Q101认证，满足车规认证需求，满足IOS-7637-2标准；工作温度范围-55℃~150℃，良好适应整车恶劣工况。

图3：SM8S36CA封装以及功能图框

除了上述优势，SM8S36CA为国产元器件，在交期、价格方面更具优势，有需求欢迎在联系。

【经验】如何区分瞬态抑制二极管的方向

TVS二极管在测试前要先区分其单双向。虽然最终的作用是一样的，但是单双向TVS二极管的适用范围还是有差别的，双向TVS管适用于交流电路，单向TVS管一般用于直流电路。本文的目的是教大家如何区分瞬态抑制二极管的方向。
