PC817 OPTOCOUPLER DIP

📄 Description

The PC817 Optocoupler (also known as a photocoupler) is widely used for signal isolation between different voltage sections of a circuit. It contains an infrared LED and a phototransistor housed in a 4-pin DIP package.

This makes it perfect for interfacing microcontrollers with high-voltage circuits, preventing noise and voltage spikes from damaging sensitive components.
