PC817 datasheet

pc817According to PC817 datasheet it 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.

PC817 features

  • 4 pin 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)
  • Lead-free and RoHS directive compliant

PC817 applications

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