The MCT26 optoisolator is a transistor photo-voltaic output designed to isolate circuits from one another. It is a completely self-contained optocoupler consisting of a gallium arsenide infrared LED and a silicon NPN photo-transistor. The MCT26 isolator is suitable for a wide range of applications, including protection between high-voltage and low-voltage electrical circuits, signal isolation in industrial instrumentation, protection in audio equipment and on-board control of a wide range of motor drive systems.

The optoisolator works by using a light-emitting diode (LED) to transmit light to a photo-transistor. The LED is powered by an external dc power supply, which creates the optical energy that is transferred to the photo-transistor through a light conducting medium. This optical energy causes an electrical current to flow through the photo-transistor, completing the circuit. This action results in the creation of an electrostatic field, which isolates the two circuits electrically.

The design of the MCT26 incorporates a silicon NPN transistor that responds only to light and is designed to provide excellent isolation and switching characteristics. Compared to other optocouplers the MCT26 offers both better input/output symmetry and superior crosstalk performance with minimum rise/fall times. Its wide operating range, coupled with low power consumption and compatibility with digital circuits, makes it a great choice for many applications.

The MCT26 optoisolator is ideal for applications that require electrical isolation such as medical equipment, power supplies, industrial instrumentation, consumer electronics, motor control systems, communication systems and many more. It can provide additional safety for users by preventing electric shocks, protect sensitive components from potential damage caused by electrical spikes and provide a clean signal across long distances. It can also reduce electromagnetic interference (EMI) from getting into the circuit and help reduce ground loop currents.

The MCT26 optoisolator offers excellent performance and reliability, making it a logical choice for applications requiring industrial-grade safety and performance. Its wide operating range and low power consumption make it perfect for power-sensitive applications. In addition, its compatibility with digital circuits facilitates design integration and offers easy integration into embedded systems.

The MCT26 optoisolator provides acoustic insulation between two circuits and has a low power consumption. With its robust construction and wide operating range, this optoisolator ensures reliable operation and a long service life. It is also a cost-effective solution offering a great combination of performance, cost efficiency, and safety.
