PC817 Optocoupler DIP-4 Phototransistor Output – 2 Pieces

QAR 1.00/ unit

Description

The PC817 is a compact optocoupler (optoisolator) designed to provide electrical isolation between low-voltage control circuits and higher-voltage or noisy signal lines. It uses an internal infrared LED and phototransistor to transfer signals optically without direct electrical connection. This isolation protects sensitive microcontrollers and logic circuits from voltage spikes, noise, and ground loops. With a high isolation voltage of 5000Vrms , the PC817 is widely used in power supplies, switching circuits, PLC interfaces, and microcontroller isolation systems. Features • Infrared LED input for optical signal transmission • Phototransistor output for isolated switching • High isolation voltage (5000Vrms) • Low input current requirement • Wide current transfer ratio (50% to 600%) • Compact DIP-4 package • Through-hole mounting • Suitable for logic-level interfacing • Protects low-voltage circuits from high-voltage transients • Good noise immunity • Fast response for low-frequency switching • Reliable signal isolation • Ideal for microcontroller and PLC interfacing • Includes 2 pieces 3D Model • Datasheet Tutorials • All About PC817 Optocoupler
