The MCT5211SR2M is an optically-isolated transistor output, photovoltaic optoisolator device designed to provide basic control functions in specified digital/analog and switching circuits. This device is designed for versatility to accommodate a variety of specific applications. It is an ideal choice for applications where optical-isolation, electrical isolation and available input voltage levels are primary requirements in a optoisolator.

The MCT5211SR2M offers superior performance, excellent safety features, easy programming and a wide variety of electrical, mechanical and optical performance characteristics.

The optoisolator\'s construction includes a light-emitting diode (LED) mounted on one side of an optically-isolated plastic package and a light-sensitive photocell with a drive transistor output all mounted on the other side. The LED and photocell are aligned in close proximity so that the LED light projects directly to the photocell. The LED\'s anode and cathode are connected directly to the photocell\'s anode and cathode, respectively. When the LED is energized, current passes through the optoisolator, and the current activates the switching element.

The MCT5211SR2M also features a built-in active output stage with an adjustable drive current. The output drive current is adjustable via a trimmer pot, allowing for further optimization of output current to match the requirements of each application. This ensures that the optoisolator can be used in a variety of applications and environments.

In addition to its superior performance, the MCT5211SR2M provides comprehensive safety features including a rapid quenching circuit and an output drive current control circuit. The quenching circuit rapidly reduces the drive current of the device when a fault is detected, ensuring that the optoisolator remains in a safe operating state at all times. The output drive current control circuit also helps in maintaining an optimal output current level, ensuring that the device is operated below its rated threshold.

The MCT5211SR2M is a highly-reliable optoisolator device, offering a wide range of physical and electrical characteristics that make it suitable for a variety of applications. The device is particularly well-suited for applications such as engineering, manufacturing and industrial control systems, where optical isolation, electrical isolation, and precise control over output drive current are key requirements.
