PC817

PC817 is a 4 Pin optocoupler, consists of an Infrared Emitting Diode (IRED) & photo transistor, which enables it optically connected but electrically insulated. PC817 is also known as an optocoupler / optoisolator. It consists of Infrared Emitting Diode (IRED). This IRED is coupled to a photo transistor optically and not electrically. It is closed in a four (4) pin package. This package is usually available in two different forms. The first one is wide lead (Pb) spacing option and the second one is SMT gullwing lead form option.
