DESCRIPTION
The IL400 is an optically coupled SCR with a Gal-
lium Arsenide infrared emitter and a silicon photo
SCR sensor. Switching can be achieved while main-
taining a high degree of isolation between triggering
and load circuits. The IL400 can be used in SCR
triac and solid state relay applications where high
blocking voltages and low input current sensitivity
are required.
