TLP521-4GB is an integrated circuit which is known as phototransistor .The phototransistor is a semiconductor device that is able to sense light levels and alter the current flowing between emitter and collector according to the level of light it receives. Phototransistors and photodiodes can both be used for sensing light, but phototransistor is more sensitive in view of the gain provided by the fact that it is a bipolar transistor. This makes phototransistors more suitable in a number of applications.
