DESCRIPTION
The 4N39 is an optically coupled SCR with a Gal-
lium 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 blocking voltages and low input current
sensitivity are required.
