Description

The MOC3051 is an electronic component model in the Triac & SCR Output Optocouplers product category. It consists of a GaAs infrared LED optically coupled to a non-Zero-crossing silicon bilateral AC switch (triac). This component is designed to isolate low voltage logic from 115 and 240 Vac lines, providing random phase control of high-current triacs or thyristors. It also features greatly enhanced static dv/dt capability to ensure stable switching performance of inductive loads.
