时源芯微专业EMC/EMI/EMS整改 EMC防护器件
这张电路图展示了一个符合IEC 61000-4-2标准的电压取样端口静电浪涌防护方案，下面是对该方案的详细描述：
工作原理
该方案的核心在于通过保护二极管和TVS（瞬态电压抑制）元件来限制过压。当静电浪涌来临时，这些元件会迅速响应，将过高的电压钳位到一个安全的水平，从而确保后端电路不受损害。
实现方式
在电路图中，每个线路（L1到N）上都连接了一个保护二极管D1。
这些二极管的主要作用是防止电压反向流动，从而保护电路免受反向电压的冲击。
电阻在电路中起到限流和分压的作用；它们可以限制通过保护元件的电流，防止过大的电流损坏元件，确保电路的稳定运行。
TVS元件是一种高效的电路保护器件，具有极快的响应时间和很高的浪涌吸收能力。
当静电浪涌来临时，TVS元件会迅速导通，将浪涌电压钳位到一个安全的水平，从而保护后端电路免受损害。
齐纳二极管是一种特殊的二极管，可以在反向击穿状态下工作，并且具有稳定的击穿电压。
在这个防护方案中，齐纳二极管用于进一步稳定电压，确保电压在安全的范围内波动。
关键元件的作用
通过这些元件的协同工作，该防护方案能够有效地吸收和分流静电浪涌，保护电压取样端口免受损害，确保电路的稳定运行。
