可控硅方可關(guān)斷。當(dāng)然,如果Ea極性反接,BGBG2由于受到反向電壓作用將處于截止?fàn)顟B(tài)。這時(shí),即使輸入觸發(fā),可控硅也不能工作。反過(guò)來(lái),Ea接成正向,而發(fā)是負(fù)的,可控硅也不能導(dǎo)通。另外,如果不加觸發(fā),而正向陽(yáng)極電壓大到超過(guò)一定值時(shí),可控硅也會(huì)導(dǎo)通,但已屬于非正常工作情況了??煽毓柽@種通過(guò)觸發(fā)(小的觸發(fā)電流)來(lái)控制導(dǎo)通(可控硅中通過(guò)大電流)的可控特性,正是它區(qū)別于普通硅整流二極管的重要特征。普通可控硅的三個(gè)電極可以用萬(wàn)用表歐姆擋R×100擋位來(lái)測(cè)。大知道,晶閘管G、K之間是一個(gè)PN結(jié)(a),相當(dāng)于一個(gè)二極管,G為正極、K為負(fù)極,所以,按照二極管的,找出三個(gè)極中的兩個(gè)極。
