MOC3021 Triac drive Optoisolator pinout, working, examples
MOC3021 is a non-zero crossing based optoisolator consists of gallium arsenide infrared emitting diodes, optically coupled to a silicon-based triac. Optocoupler has multiple types and every type has almost the same operating functionality, but sometimes its internal structure makes it different from another optocoupler. There is also a TRIAC based optocoupler known as MOC3021. It … Read more
