PC817C DIP-4 Optocoupler

The PC817 is an optocoupler that electrically isolates input and output circuits. It consists of an infrared LED and a phototransistor in a single package. When the LED is activated, the phototransistor conducts, allowing signal transmission with electrical isolation, commonly used in power supply circuits and signal isolation applications.
