PC817 Description

Short technical summary and product information.

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. This configuration allows for electrical isolation between circuits.

 

The PC817 operates with 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 at 5mA. The device exhibits a cut-off frequency of 80 kHz, with rise and fall times of 18µs each. The collector-emitter saturation voltage is typically between 0.1V and 0.2V under specific conditions.

 

This photocoupler is available in a 4-DIP package with a lead spacing of 7.62mm, suitable for through-hole mounting. It can also be found in SMT gullwing lead form options. The operating temperature range is from -30°C to +100°C, with a storage temperature range of -55°C to +120°C. The maximum collector dissipation is 200mW.

 

The PC817 is commonly used in applications requiring electrical isolation. Its design allows the phototransistor's base to activate when the LED emits light, controlling the output. The device is typically configured in a common-emitter setup.
