Detailed Overview
The MOC3021 is a TRIAC driven zero-crossing optocoupler, utilizing light to indirectly couple circuits and provide robust electrical isolation. The output is driven by a TRIAC, enabling it to drive loads up to 400V and conduct in both directions, making it ideal for controlling AC loads. The zero-crossing ability ensures that the TRIAC starts conducting only after the AC wave reaches 0V when the AC load is switched on, effectively preventing damage from peak voltages. Control loads by simply turning the LED on or off, or leverage PWM signals to precisely control the output voltage, thereby managing the speed/brightness of the load.
