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.
