The PC817 SMD Optocoupler is a high-density mounting type photocoupler designed for effective signal isolation and switching in electronic circuits. This optocoupler integrates an infrared LED and a phototransistor in a compact dual-in-line (DIP) package, offering reliable electrical isolation between input and output. Its high isolation voltage ensures safe operation, making it suitable for both consumer and industrial electronics. The PC817 is ideal for computer terminals, system appliances, measuring instruments, registers, copiers, vending machines, and household appliances such as fan heaters, power supplies, and motor controllers.
