PC817 Optocoupler

PC817 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.

Features:-

• 4pin DIP package
• Double transfer mold package (Ideal for Flow Soldering)
• High collector-emitter voltage (VCEO:80V(*))
• Current transfer ratio (CTR : MIN. 50% at IF=5 mA, VCE=5V)
• Several CTR ranks available
• High isolation voltage between input and output (Viso(rms) : 5.0 kV)

Application:-

•  I/O isolation for MCUs (Micro Controller Units)
• Noise suppression in switching circuits
• Signal transmission between circuits of different potentials and impedances
