PT4800F Working Principle

A phototransistor is a type of transistor which is designed to respond to light signals. Unlike regular transistors, which respond to electrical signals, phototransistors are designed to be activated by the presence of light. The PT4800F operates using the principle of photoconduction, which is the conversion of light into an electrical current. When the device is exposed to a light signal, its base-emitter junction becomes forward-biased, which in turn activates the transistor and allows a current to flow through. This basic principle has been adopted in many sensing applications and provides a reliable and effective means of light detection.
