The PC817 is a general-purpose photocoupler, also known as an optocoupler or optoisolator, designed for separating two circuits. It consists of an infrared emitting diode (IRED) optically coupled to a phototransistor. This configuration allows for electrical isolation between the input and output.
Key electrical specifications include a maximum collector-emitter voltage of 80V and a maximum collector current of 50mA. The input diode has a typical forward voltage of 1.25V. The device operates with a cut-off frequency of 80 kHz, a rise time of 18µs, and a fall time of 18µs. The phototransistor is of the NPN type.
This optocoupler is available in a 4-DIP through-hole package, with a 0.300-inch (7.62mm) lead spacing. It is suitable for applications requiring electrical isolation. The operating temperature range is from -30°C to +100°C.
The PC817 is commonly used in various electronic circuits where signal isolation is necessary, preventing high voltages or noise from affecting sensitive control circuitry.
