The MOC3021 IC is a non-zero crossing, 6-pin Optocoupler composed of a gallium arsenide infrared emitting diode as input and a light-activated silicon bilateral switch called a TRIAC as output. It is intended for use in circuit applications that require the control of high AC power mains from a low voltage circuit while protecting or isolating the low voltage circuit from the dangers of alternating current power mains high voltage. The MOC3021 IC TRIAC driver output can provide a current that can reach 1A and its voltage can reach 400V. It is commonly used in light dimmers, fan speed controllers, motor speed controllers, and so on. An alternative option to this IC the MOC3041 Zero Cross Opto-isolator Triac Driver IC.
