Phototransistor circuit

Published:2011/6/29 2:47:00 Author:Christina | Keyword: Phototransistor

If you connect the phototransistor in this circuit, the collector of the phototransistor is connected with the positive potential, the emitter of it is connected with the negative potential. When there is no light irradiation, the current which flows through the phototransistor is the Iceo between the electrode and the emitter of the phototransistor, it is the dark current of the phototransistor: Iceo=(l+hFE)Icbo. In this formula: Lcbo--the saturated current between the collector electrode and base electrode;hFE--the DC amplification coefficient of the common-emitter. The phototransistor has the higher sensitivity than the photosensitive diode.   (View)
