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 applica-
tions where high blocking voltages and low input
current sensitivity are required.
