Photo Transistor

A transistor optocoupler is a device that combines two components, a transistor and an optocoupler. It is a device composed of a light emitting diode, a photosensitive triode and a transistor. The transistor optocoupler has isolation properties and amplification functions, and can be used to isolate high-voltage circuits from low-voltage circuits, or used to realize functions such as photoelectric control.
