在伺服电机控制系统中，各种保护器件（PTC、FUSE、ESD）无处不在，电源端保护、CAN通信保护、IGBT模块驱动栅极钳位保护等等。本文将主要介绍CAN通信保护ESD器件 SE24T2T02GZ用于伺服电机控制系统的ESD保护。伺服电机控制系统的电路框架图如下所示：

由图可知，伺服电机控制系统的电路框架主要由功率单元、电机单元、控制单元、通信单元及电源管理单元组成，需要注意该电源管理单元可提供的供电系统一般为12V或24V，为避免因静电、雷击等因素造成CAN通信干扰，需要在CAN总线端接入TVS管阵列做防雷保护，在此选用了硕凯的SE24T2T02GZ。

硕凯的SE24T2T02GZ是专门防止这些干扰因素的ESD类型的CAN回路应用的TVS保护器件，24V规格，SOT-23封装，集成两路双向的TVS，采用1PCS可同时对CANH和CANL进行ESD钳位保护。另外，SE24T2T02GZ静电等级非常的高，空气静电和接触静电高达30KV，有效避免空气静电和接触静电的干扰。

最后，硕凯作为优秀国产保护器件厂家，交期和价格都非常有优势，是国产化替代的优选品牌。
