PC817 Optocoupler (Pack Of 5)

Description

1. Optical Isolation: The PC817 optocoupler provides electrical isolation between the input and output, protecting sensitive components or circuits from voltage spikes, noise, or interference.
2. Infrared Emitter (LED): The input side of the PC817 contains an infrared LED that emits light when forward-biased with a small current. This light is used to transmit signals to the output side.
3. Phototransistor: The output side of the PC817 features a phototransistor that detects the emitted infrared light and produces an electrical current in response to it. This current can be used to control or monitor another circuit.
4. High Isolation Voltage: The PC817 is designed to handle relatively high isolation voltage levels, making it suitable for applications with voltage spikes or high potential differences between input and output.
5. Compact and DIP Package: The PC817 is often available in a Dual Inline Package (DIP) with through-hole pins, which makes it easy to mount on a circuit board.
