概述 Description
瞬态抑制二极管 (TVS) 是一种电路保护元件，它可以削
弱或过滤突增的瞬态电压(过压)，在浪涌到来瞬间几纳
秒时间内发生雪崩击穿，将浪涌电流引至��地端，并将
电压箝位在安全范围内，从而实现了高效能的电压保护
Transient Voltage Suppressor (TVS) is a circuit
protection component that either attenuates (reduces)
or filters a transient voltage spike (overvoltage), TVS
diodes provide critical protection by going into
avalanche breakdown within no more than a few
nanoseconds after a strike, clamping the transient
voltage, and routing its current to the ground.
