PC817 Optocoupler / Opto-Isolator IC - DIP
The PC817 is a single-channel photocoupler (optocoupler) that electrically isolates two circuits. It contains an infrared LED on the input side and a phototransistor on the output side. When current flows through the LED, it produces infrared light that turns on the phototransistor, transferring the signal without a direct electrical connection.
The PC817 is commonly used for signal isolation between high- and low-voltage circuits , such as microcontroller interfaces, power supplies, relay drivers, and industrial control circuits. It is typically available in a 4-pin DIP package .
