    The phototransistor can be viewed as a photodiode whose output current is fed into the base of a conventional transistor. These photodiode-amplifier combinations are put together to overcome the major limitation of photodiodes: unity gain. The typical gain of a phototransistor can range from 100 to over 1500. Many applications …

  • Photodiode/Phototransistor Application Circuit

    Working Explanation. This circuit works such that photoresistor, at first, will detect light. The base of the phototransistor is exposed to the environment. Thus, the photons from light strikes onto the base of the photoresistor. When there is no light, a signal is produced by the phototransistor that will trigger the 2N2222 transistor.
