MOC3021 IC – Optocoupler Traic Driver IC
The MOC3021 is a device that can drive a triac using optical isolation. It has a GaAs infrared diode that emits light and a silicon bilateral switch that acts like a triac when exposed to light. This device is meant to connect electronic controls and power triacs for controlling 115VAC resistive and inductive loads.
Features
Excellent IFT stability—IR emitting diode has low degradation.
High isolation voltage—minimum 5300 VAC RMS
Underwriters Laboratory (UL) recognized File #E90700
Peak blocking voltage: 400V-MOC3021
VDE recognized (File #94766)
