DESCRIPTION
The MOC3051-M and MOC3052-M consist of a AlGaAs infrared emitting diode optically coupled to a non-zero-crossing silicon
bilateral AC switch (triac). These devices isolate low voltage logic from 115 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 perfor-
mance of inductive loads.
