4N39 Datasheet (Siemens Semiconductor Group)

4N39, PHOTO SCR OPTOCOUPLER

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.

The 4N39 can be used in SCR triac and solid state relay applications where high b
