【选型】电安科技ESD阵列TPA23C-24M符合车规要求，可应用于汽车OBC的CAN总线保护
CAN总线是汽车OBC上常用的总线通讯方式之一，总线通信一般需增加ESD类型的保护器件，CAN总线为双线传输类型，其传输速率可高达10MB/S，ESD保护器件需求低容值，防止电容过大影响信号失真。本文介绍电安科技车规ESD阵列产品TPA23C-24M，可用于车载OBC产品的CAN保护。
图1——CAN收发器典型应用电路
电安科技车规ESD阵列产品TPA23C-24M具有以下特点：
1、TPA23C-24M的反向截止电压是24V，最大钳位电压48V，可满足12V供电系统的运用；
2、TPA23C-24M接触放电达到30KV，空气放电30KV，具有高静电等级；
3、CAN总线为双线传输类型，TPA23C-24M为SOT-23封装，双路双极性产品，可替代两颗ESD保护产品，且占用设计空间更小；
4、容值5pF，在CAN总线上能够起到静电保护作用又不影响线路通信；
5、符合AECQ‐101，工作结温-55℃~125℃，宽温度范围，具有高可靠性；
