MOC3041 IC – Zero-Cross Optoisolator Triac Driver IC
The MOC3041, MOC3042, and MOC3043 devices consist of gallium arsenide infrared emitting diodes optically coupled to a monolithic silicon detector performing the function of a Zero Voltage Crossing bilateral Triac driver. They are designed for use with a triac in the interface of logic systems to equipment powered from 115 Vac lines, such as solid-state relays, industrial controls, motors, solenoids, and consumer appliances, etc. The MOC3041 is a Zero-Crossing TRIAC driven Optocoupler. Meaning it has an Infra-red Light Emitting Diode (LED) inside it coupled with a TRIAC. When the LED is triggered the TRIAC is also turned on. An optoisolator like MOC3041 is normally used to control another external switching device like a TRIAC, MOSFET or SCR which in turn will control an AC or DC load. The TRIAC present inside the MOC3041 can provide up to 1A peak current which is high enough to trigger an external switch. The TRIAC by itself should not be used to switch loads without an external switch.
