The MOC3021 is a Triac Driven Optoisolator designed for controlling AC loads. It integrates a zero-crossing TRIAC driver, which ensures that the TRIAC begins conduction only when the AC wave reaches 0V. This feature helps prevent direct peak voltages from damaging the load.
Key electrical specifications include a typical LED forward voltage of 1.15V at 15mA and a maximum TRIAC output terminal voltage of 400V. The TRIAC can handle a peak output current of 1A. This optoisolator is available in a 6-pin PDIP package.
Its zero-crossing ability and TRIAC output make it suitable for controlling high-voltage AC loads through digital controllers like microprocessors or microcontrollers. Applications include dimming lights or controlling the speed of AC motors. The MOC3021 is typically used to switch a power TRIAC, which then drives the load, due to the optocoupler's limited current rating.
The maximum TRIAC output terminal voltage is 400V.
