【应用】力特TVS二极管SMAJ5.0CA用于伺服驱动器IO口保护，峰值脉冲功耗高达600W

时间： 2022-12-02 来源：世强

技术问答

主控单元是伺服驱动系统的核心，它与外部连接的IO口容易收到雷击、浪涌等影响，严重的会破坏主控的IO口。为了防止干扰信号损坏IO口，对主控单元造成影响，需要有较高的脉冲功率耗散和ESD防护等级的TVS，串联在需要保护的IO口和地之间。

有客户在设计总线型伺服驱动器时，需要TVS二极管用于主控单元中IO口的保护。根据上文所指出的需求，我们推荐了力特的TVS二极管SMAJ5.0CA，它反向峰值电压VRWM为5V，最大钳位电压VC为9.2V，最大反向漏电流Ir为800μA，满足主控单元IO口保护的需求；峰值脉冲功耗（@堆叠封装）高达600W，浪涌电流承受能力强；ESD防护等级满足±30kV，静电防护等级强；工作温度范围-65℃~150℃，保证伺服驱动系统在工业环境下工作的可靠性。

图1. SMAJ5.0CA在伺服驱动器中的应用

SMAJ5.0CA产品特点：

1、峰值脉冲功耗（@堆叠封装）高达600W，浪涌电流承受能力强，保护伺服系统的稳定性；

2、ESD防护等级±30kV，静电防护电压等级高，满足伺服系统的可靠性与稳定性需求；

3、工作温度范围-65℃~150℃，工作温度范围宽，保证伺服驱动系统在工业环境下工作的可靠性；

综上所述，力特TVS二极管SMAJ5.0CA适用于伺服驱动系统主控单元IO口保护中。
