TVS1和TVS2在ESD保护中的作用
在电路图中,TVS1和TVS2作为瞬态电压抑制二极管,被用于提供ESD保护。它们的工作原理是:当在其两端施加高于其击穿电压的瞬态电压时,TVS会迅速导通,将电压钳位在一个安全的水平,从而防止过电压对电路元件造成损害。
TVS1的详细信息及作用
- 型号:6TS440CA
- 封装:SMB
- 反向截止电压(VRWM):440V
- 峰值脉冲电流(IPP@10/1000μs):0.9A
- 峰值脉冲功率(PPP):600W
TVS1位于电路的输入端,连接在220Vrms交流输入与整流桥BR1之间。由于其较高的反向截止电压(440V),TVS1能够有效地保护电路免受输入侧的高电压瞬态冲击,如雷击或电网波动。在ESD事件中,TVS1能够迅速响应,将电压钳位在安全范围内,防止过电压对整流桥BR1及后续电路造成损害。
TVS2的详细信息及作用
- 6TS18CA TVS2
- 反向截止电压(VRWM):18V
- 峰值脉冲电流(IPP@10/1 000μs):21.2A
- 6TS6.0CA TVS2
- 反向截止电压(VRWM):6V
- 峰值脉冲电流(IPP@10/1000μs):58.26A
这两个TVS2二极管位于电路的输出端附近,并联在输出线上。由于它们具有较低的反向截止电压(分别为18V和6V),因此能够有效地保护电路免受输出侧的低电压瞬态冲击,如静电放电。在ESD事件中,TVS2能够迅速导通,将电压钳位在安全范围内,防止过电压对负载或其他关键组件造成损害。
