DC-Input Multi-Channel Full-Pitch Phototransistor Optocoupler

Currently Viewing:

Broadcom ACPL-827 is a DC-input dual channel full-pitch transistor optocoupler which contains two light emitting diode optically coupled to two separate transistor. It is packaged in a 8-pin DIP package.

It is also available in wide-lead spacing option and lead bend SMD option with input-output isolation voltage at 5000 Vrms. Response time, tr, is typically 4 μs and minimum CTR is 50% at input current of 5 mA.


  • Current transfer ratio
    (CTR: min. 50% at IF = 5mA, VCE = 5V)
  • High input-output isolation voltage
    (VISO = 5,000VRMS)
  • Response time
    (tr: typ. 4μs at VCE = 2V, IC = 2mA, RL= 100¿)
  • Compact dual-in-line package
  • Safety and regulatory approvals
    - CSA
    - UL 1577
    - IEC/EN/DIN EN 60747-5-2
  • Options available are:
    W00 = 0.4" Lead Spacing Option
    300 = Lead Bend SMD Option
    500 = Tape and Reel Packaging Option
    00B = Rank Mark B
    00C = Rank Mark C
    000E = Lead Free Option
