AC-Input Lead Free General Purpose Phototransistor Optocoupler

Currently Viewing:

The HCPL-814-000E optocoupler contains a phototransistor, optically coupled to two light emitting diodes connected inverse parallel. It can operate directly by AC input current. It is packaged in a 4-pin DIP package and available in widelead spacing option and lead bend SMD option. Input-output isolation voltage is 5000 Vrms. Response time, tr, is typically 4 ms and minimum CTR is 20% at input current of 1 1 mA.



  • AC input response
  • High input-output isolation voltage (Viso = 5,000 Vrms)
  • Low collector dark current
    (ICEO: max. 10-7 A at VCE = 20 V)
  • Current transfer ratio
    (CTR: min. 20% at IF = /-1 mA, VCE = 5 V)
  • Response time
    (tr: typ. 4 us at VCE = 2 V, IC = 2 mA, RL = 100 Ohms)
  • Compact dual-in-line package
  • UL approved
  • CSA 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
    00AE = Rank Mark A
