The MOC3051M, MOC3052M and MOC3053M consist of a GaAs

infrared emitting diode optically coupled to a non−zero− crossing

silicon bilateral AC switch (triac). These devices isolate low voltage

logic from 115 VAC and 240 VAC lines to provide random phase

control of high current triacs or thyristors. These devices feature

greatly enhanced static dv/dt capability to ensure stable switching

performance of inductive loads.

Features

• Excellent IFT Stability—IR Emitting Diode Has Low Degradation

• 600 V Peak Blocking Voltage
