The PC817 is a general-purpose photocoupler, also known as an optoisolator, designed for separating two circuits. It consists of an infrared emitting diode (IRED) optically coupled to a phototransistor within a four-pin package. This configuration allows for electrical isolation between the input and output circuits.
Key electrical specifications include a maximum collector-emitter voltage of 80V and a maximum collector current of 50mA. The typical forward voltage for the input diode is 1.25V at 5mA, with a minimum current transfer ratio of 50% at 5mA. The device operates within a temperature range of -30°C to 100°C.
The PC817 is available in a through-hole mounting type, specifically a 4-DIP package with 0.300-inch (7.62mm) lead spacing. This package type is suitable for flow soldering. The optocoupler functions by activating the phototransistor when the internal LED emits light, enabling current flow between the output pins.
