4N35 - Phototransistor Optocoupler


The 4N35 is an optocoupler for general purpose applications. It contains a light emitting diode optically coupled to a phototransistor. It is packaged in a 6-pin DIP package and available in widelead spacing option and lead bend SMD option. Response time, tr, is typically 3 μs and minimum CTR is 100% at input current of 10 mA.


  • High Current Transfer Ratio (CTR: min. 100% at IF = 10 mA, VCE = 10 V)
  • Response time (tr: typ., 3 μs at VCE = 10 V, IC = 2 mA, RL = 100 Ω)
  • Input-output isolation voltage (Viso = 3550 Vrms)
  • Dual-in-line package
  • UL approved
  • CSA approved
  • IEC/EN/DIN EN 60747-5-2 approved
  • Options available:
    • Leads with 0.4" (10.16 mm)


  • I/O interfaces for computers 
  • System appliances, measuring instruments
  • Signal transmission between circuits of different potentials and impedances
