瞬态电压抑制二极管的工作原理

发布日期:2019-12-20 作者: 点击:

  瞬态电压按捺二极管双色球蓝球走势图的工作原理是利用PN结的齐纳击穿性而作业的,每一个PN结都有自己的反向击穿电压UB。例如UB为200V,当施加到PN结的反向电压小于200V时,电流不导通,而当施加到PN结的反向电压高于200V时,PN结快速进入击穿状况,有大电流经过PN结,而UB电压约束在200V附近。根据这个道理,在电路中有浪涌电压产生时,瞬态电压按捺二极管可将高压脉冲约束在安全范围内,而允许瞬间大电流旁路。因而瞬态电压按捺二极管可用于电路过压维护。从结构上讲双极型的芯片不是简略地由两个背对背的单极芯片串联而成,而是利用现代半导体加工技术在同一硅片的正反两个面上制造两个背对背的PN结,它用于双向过压维护。
