Description

The MOC3081M, MOC3082M and MOC3083M devices

consist of a GaAs infrared emitting diode optically

coupled to a monolithic silicon detector performing the

function of a zero voltage crossing bilateral triac driver.

They are designed for use with a discrete power triac in

the interface of logic systems to equipment powered

from 240 VAC lines, such as solid-state relays, industrial

controls, motors, solenoids and consumer appliances,

etc.
