【应用】国产车规级TVS管TPA23C-24有效保护CAN总线，贴片SOT23-3封装，功率280W

时间： 2021-07-20 来源：电安科技

技术问答

CAN总线由于其高可靠和实时性被广泛应用于新能源汽车、轨道交通、医疗、工业控制等行业。对于设计人员来说，这意味着他们必须考虑宽频率范围内的电噪声环境——从高频辐射电磁干扰 (EMI) 到共模传导干扰，及各种负载的连接和断开引起的电压尖峰。虽然CAN总线适用于恶劣的电气环境，但如果没有适当的保护，它们很容易出现各种故障模式。针对以上保护需求，电安科技推出双向、高功率、车规级TVS TPA23C-24，它能对CAN总线上的瞬间冲击脉冲起到有效的保护作用。

如图1所示，就是TPA23C-24在CAN总线电路保护上的典型接法。

其特点如下：

1、专门针对CAN总线保护设计，贴片SOT23-3封装，功率280W；

2、双极性设计；

3、低钳位电压，低漏电流；

4、符合AEC-Q101认证要求；

5、抗ESD能力-接触、空气都为±30KV

5、国产器件，交期价格有优势；
