The PC817C with DIP-4 Optocoupler is manufactured by Youtai and is designed to provide electrical isolation between two circuits by converting electrical signals from input to output. It is a 4-pin, metal-encased optocoupler, or optically coupled isolator, with a phototransistor output and ROHS-compliant construction. It is a single channel device with a phototransistor output, and is well-suited for applications such as current sensing, motor speed control, and noise reduction. The optocoupler features a wide, 8 kV max. isolation voltage, a broad spectrum of collector-emitter voltages (6.0 to 60 V), and fast-switching response times (typical 5µs). The PC817C is RoHS compliant, and is suitable for use in a wide range of industrial, automotive, communications, and LED applications.
