MOC3021 Optocoupler Triac Driver IC
MOC-3021 is a triac driven zero-crossing optocoupler. Optocoupler is made of light-emitting and light-sensing devices with no internal connection except light bean. The opto isolators allow two circuits to exchange signals without making any electrical connection.
This device works on the principle that light is proportional to signal and signal is transferred to a phototransistor. Opto-isolators or Opto-couplers are made up of a light-emitting device, and a light-sensitive device, all wrapped up in one package, but with no electrical connection between the two, just a beam of light. The light emitter is nearly always an LED.
