With this mode of working the base-emitter circuit is the input side;and the emitter through base to collector circuit the output side.although these have a common path through base and emitter, the two circuit are effectively separated by the fast that as far as polarity of the base circuit is concerned,the base and upper half of the transistor are connected as a reverse biased diode.hence there is no current flow from the base circuit into the collector circuit.

这一工作模式下，基极-发射极电路是输入端，发射极通过基极，再到集电极电路的输出端。虽然它们都有一个共同的路径通过基极和发射极，这两个电路是通过和基极电路相关的尽可能的有效快速分离开的，基极和基极以上的一半以上的晶体管作为一个反偏二极管与之相连接。
