MOC3083FR2VM optoisolators belong to the category of “Triac, SCR Output”. It’s a type of solid state optocoupler that provides electrical isolation between two separate circuits. The optocoupler isolates two electrically separate elements by using a combination of an LED and a phototransistor, which makes it suitable for applications where very high-voltage separation is needed.

Application Field

The MOC3083FR2VM optoisolator is used primarily for signal switching and control in AC loads. Widely used in the industrial automation, electric power systems, and heating/lighting control scenarios. The optoisolator is designed to work with triac or SCR type of loads to control the power supply switches and the current flow in an AC circuit. The optoisolator can be used to switch different types of loads like resistive, inductive, or capacitive.

Working Principle

The design of the MOC3083FR2VM optoisolator employs an LED, which transfers the input signal from the control circuit to a phototransistor. Upon energizing, the LED emits infrared light, which is received by the phototransistor to achieve electrical isolation between the input signal and the output load. The light generated by the LED also serves to trigger the external triac or SCR to activate the load circuit.

To summarize, the MOC3083FR2VM optoisolator provides electrical isolation between two distinct circuits permitting AC load current flow control and switching with the help of an LED and a phototransistor. The device is widely used in industrial automation, heating/lighting control, and power systems.
