MOC3021 Optocoupler is Triac driven a zero-crossing optocoupler. Optocoupler is made of light-emitting and light-sensing devices with no internal connection except light bean. The optoisolators allow two circuits to exchange signals without making any electrical connection. This device works on the principle that light is proportional to signal and the signal is transferred to a phototransistor. Features of MOC3021 Optocoupler:

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– 250V-MOC301XM – 400V-MOC302XM

APPLICATIONS of MOC3021

Industrial controls
Solenoid/valve controls
Traffic lights
Static AC power switch
Vending machines
Incandescent lamp dimmers
Solid state relay
Motor control
