Lead Free General Purpose Phototransistor Optocoupler

Currently Viewing:

The CNY17-3-000E optocoupler contains a light emitting diode optically coupled to a phototransistor. It is packaged in a 6-pin DIP package and available in wide-lead spacing option and lead bend SMD option. Collector-emitter voltage is above 70 V. Response time, tr, is typically 5 us and minimum CTR is 40% at input current of 10 mA.



  • High collector-emitter voltage (VCEO = 70 V)
  • High input-output isolation voltage (Viso = 5000 Vrms)
  • Current Transfer Ratio (CTR: min. 40% at IF = 10 mA, VCE = 5 V)
  • Response time (tr: typ., 5 ms at VCC = 10 V, IC = 2 mA, RL = 100 Ohms)
  • Dual-in-line package
  • UL approved
  • CSA approved
  • IEC/EN/DIN EN 60747-5-2 approved
  • Options available are:
    060E = IEC/EN/DIN EN 60747-5-2 Option
    W00E = 0.4" Lead Spacing Option
    300E = Lead Bend SMD Option
    500E = Tape and Reel Packaging Option


  • System appliances, measuring instruments
  • Signal transmission between circuits of different potentials and impedances
  • Feedback circuit in power supply
