Pc817 Photocopier Opto Isolator

PC817 Photocopier Opto Isolator is 4 pins general-purpose optocoupler of generally used as an isolator between high voltage to low voltage;Description Of PC817; PC817X Series contains an IRED optically coupled to a phototransistor. It is packaged in a 4pin DIP, available in wide-lead spacing option and SMT gullwing lead-form option. Input-output isolation voltage(rms) is 5.0kV. Collector-emitter voltage is 80V(*) and CTR is 50% to 600% at input current of 5mA. Applications.  I/O isolation for MCUs (Micro Controller Units)  Noise suppression in switching circuits  Signal transmission between circuits of different potentials and impedances
