還有對電信號放大的功能一般光敏三極管只引出
兩個極——發(fā)射極和集電極基極不引出
管殼同樣開窗口以便光線射入為增大光照基區(qū)面積做得很大

dark current Iceo = (1 + β) Icbo
smallsmaller than the average current through the transistor
發(fā)射區(qū)較小入射光主要被基區(qū)吸收
The current flowing through the tube
工作時集電結反偏發(fā)射結正偏在無光照時
管子流過的電流為暗電流Iceo=(1+β)Icbo(很小)，比一般三極管的穿透電流還小
