MOC3021 - Triac Driven Optocoupler
The MOC3021 is an optically Isolated Triac Driver Device, contains a GaAs infrared emitting diode and a light activated silicon bilateral switch, which functions like a triac. This device is designed for interfacing between electronic controls and power triacs to control resistive and inductive loads for 115VAC operations.
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
