Phototransistors are light-sensitive semiconductor devices that convert optical signals into electrical currents. They are based on the principle of a conventional transistor, but with light serving as the control variable. In this respect, the function of a transistor is combined with that of photodiodes. Their fast response time and high sensitivity make phototransistors an efficient solution for numerous applications.

Phototransistors are often used in highly dynamic systems for radiation detection, as well as in security systems, counting systems or in lighting control. They also play a central role in communication and measurement technology.
