SKKH253/12E因元件开关损耗显着增加,允许通过的平均电流相降低,此时,标称电流应降级使用.
可控硅的优点很多,例如:以小功率控制大功率,功率放大倍数高达几十万倍;
反应极快,在微秒级内开通、关断;无触点运行,无火花、无噪音;,成本低等等.
可控硅的弱点:静态及动态的过载能力较差;容易受干扰而误导通.
可控硅从外形上分类主要有:螺栓形、平板形和平底形.
可控硅元件的结构
不管可控硅的外形如何,它们的管芯都是由P型硅和N型硅组成的四层P1N1P2N2结构.见图1.
它有三个PN结(J1、J2、J3),从J1结构的P1层引出阳极A,从N2层引出阴级K,从P2层引出控制极G,
所以它是一种四层三端的半导体器件. 可控硅结构示意图和符号图
