Description
The Fairchild MOC3021 is a zero crossing optocoupler that provides efficient and reliable isolation between high and low voltage circuits. It consists of a GaAs infrared emitting diode and a light activated silicon bilateral switch, which enables the device to control AC loads with low power consumption. The MOC3021 is designed to operate with an input current range of 10 to 25mA, and provides isolation voltage of up to 5000V RMS.

This device is commonly used in applications where galvanic isolation is necessary to protect sensitive control electronics from high voltage spikes or surges. It is particularly useful in controlling AC loads such as motors, solenoids and heaters, where the zero crossing feature ensures smooth switching and prevents high voltage transients from damaging the load. With its compact size, high isolation voltage and low power consumption, the MOC3021 is a popular choice for designers looking for reliable and efficient optocoupler solutions
