【应用】6600W国产车规双向TVS管SM8S36CA助力新能源卡车油泵控制器,可有效提供浪涌防护
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。
