4N39 - PHOTO SCR OPTOCOUPLER

General Description

The 4N39 is an optically coupled SCR with a Gallium Arsenide infrared emitter and a silicon photo SCR sensor.

Switching can be achieved while maintaining a high degree of isolation between triggering and load circuits.

Key Features

  • Turn On Current (IFT), 5.0 mA Typical.
  • Gate Trigger Current (IGT), 20 mA.
  • Surge Anode Current, 10 Amp.
  • Blocking Voltage, 200 VACPK.
  • Gate Trigger Voltage (VGT), 0.6 Volt.
  • Isolation Voltage, 5300 VACRMS.
  • Solid State Reliability.
  • Standard DIP Package.
  • Underwriters Lab File #E52744.
