PC817 Optocoupler is 4 pins general-purpose optocoupler of generally used as an isolator between high voltage to low voltage.

Features:

• 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
