An optoisolator is a device used to protect and isolate two circuits, typically from different power sources. It is made up of a light-emitting component, which is optically linked to a light detector. A wide range of optoisolators is available, including fiber-optic types, optocouplers and now even opto-transistors. The most common type is the MCT2EFR2M optoisolator, otherwise known as the photovoltaic transistor output optocoupler, due to its ability to combine optoelectronic devices and transistors in one package.

MCT2EFR2M optoisolators are typically used to protect sensitive loads like logic systems and microcontrollers from hazardous voltage levels that are above their supply voltage. In order to provide isolation, these devices rely on an optically isolated input and output. The input side provides the connection between the outer voltage and the optoisolator, and the output side provides a connection to the logic or load.

The working principle of an MCT2EFR2M optoisolator starts with the phototransistor on the input side, which is constantly exposed to a beam of light. The light beam generates a photocurrent which controls the base current of the transistor, allowing current to flow from the collector to the emitter. This enables the output of the optoisolator to be controlled by the input signal.

An MCT2EFR2M optoisolator is commonly used in the aerospace industry to provide a safe and reliable means of circuit control for in-flight systems. It is also used in medical applications to isolate critical circuits and to protect patients from potentially dangerous levels of power. In this field, the optoisolator is designed to fail safe, meaning that it will turn off an associated circuit in the event of any fault.

Other applications include automatic switch control, such as traffic light control, and low power signal relay. The MCT2EFR2M optoisolator is also widely used in audio, video, and communications signal switching, and in environments where temperature or noise may affect signal quality.

With its advantages of reliability, low power, and isolation, the MCT2EFR2M optoisolator is one of the most widely applied device options for isolating and safeguarding circuits. Its compact design makes it compatible with a wide range of circuit configurations, making it an excellent choice for many industries.
