DESCRIPTION
The IL400 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 IL400 can be used in SCR triac and solid
state relay applications where high blocking voltages
and low input current sensitivity are required.
