The PC817 Optocoupler is a high-density mounting type photocoupler widely used for signal isolation and switching applications in electronic circuits. It integrates an infrared LED and a phototransistor in a compact dual-in-line (DIP) package, providing electrical isolation between input and output while enabling reliable signal transmission.

This optocoupler is commonly used in computer terminals, system appliances, measuring instruments, registers, copiers, vending machines, and household electrical appliances such as fan heaters, power supplies, and motor controllers. With a high isolation voltage of 5300Vrms, it ensures safety and stable performance in both consumer and industrial electronics.

Features:

• High current transfer ratio (CTR: Min. 50% at IF = 5mA, Vce = 5V)

• High isolation voltage between input and output (Viso: 5300Vrms)

• Compact dual-in-line (DIP) package for easy PCB mounting

• Reliable signal isolation and switching

• Widely used in consumer and industrial electronics
