MOC3023 is an optoisolator that combines a light-activated triac with infrared LED to provide isolation of the input and output. The optoisolator restricts electrical connection between input and output to only an optical connection. This isolation allows input and output circuits to float at different potentials. The optoisolator also prevents transients from the output circuit from reaching input circuit.

The MOC3023 device provides electrical isolation of up to 5 kilovolts (kV). This insulation permits input and output circuits operating at different voltage levels. The optoisolator is specifically designed for electronic scoring systems, such as bowling alley games. It is also useful for other applications, such as electronic stovetops, dimmers, and fan regulators.

In the MOC3023 optoisolator, the input is an LED that outputs an infrared signal.The light from the LED triggers a triac on the output side. A built in optistor acts as a snubber that reduces peak current flow through the triac. This optistor also prevents high current spikes.

The MOC3023 has two different versions, a standard type and a zero-cross type. The standard type turns on when the LED input is triggered and it turns off when power is removed. The zero-cross type, however, turns on at zero-crossing. This means that the LED input is triggered when the output voltage reaches the zero-volt point. This type has a better voltage delay, which means that it is better for applications that require precise timing.

The MOC3023 has a wide range of applications. It is commonly used in electronic scoring systems, such as bowling alley games, as well as dimmers and fan regulators. It can also be used in industrial loads, voltage controllers, motor controllers, and pulse modulation applications.

In summary, the MOC3023 is an optoisolator that is used to provide electrical isolation between input and output circuits. It has two versions, a standard type and a zero-cross type, which have different voltage delays. The MOC3023 is useful for industrial loads, electronic scoring systems, dimmers, fan regulators, voltage controllers, motor controllers, and pulse modulation.
