Description

The ELT302X and ELT305X series of devices each consist of a

GaAs infrared emitting diode optically coupled to a monolithic silicon

random phase photo Triac.

They are designed for interfacing between electronic controls and

power triacs to control resistive and inductive loads for 115 to 240 VAC

operations.
