Optoisolators, also known as optocouplers, are optoelectronic devices used to isolate electrically coupled contacts. They are used to separate two circuits, allowing energy to pass through one circuit, while isolating the other from any influence of the first circuit. Optoisolators with logic output, or MID400W devices, are a family of optical isolators intended for switching and logic circuits.

MID400W devices are optoelectronic modules specifically designed for use in digital switching and logic circuits. Operating at a voltage of 5V to 15V, they provide an input/output voltage range of 10V to 24V, with current requirements of 8mA or 3.3mA. MID400W devices feature a dual-emitter LED surface on one side and a p-channel MOSFET on the other. The LED is connected to a terminal pin, whereas the MOSFET is connected via a transistor to the terminal pin, creating a close connection between the two devices. The exact operation of the MOSFET is dependent on the emitted light, and when no light is present an open circuit is maintained. When light is present, the MOSFET will close the circuit and allow current to flow.

MID400W devices are manufactured using a state-of-the-art high-efficiency process, where the optical wavelength range is minimized for greater power efficiency. This is done by reducing the emitter size and using a dichroic mirror to increase the amount of light transmitted to the MOSFET. By using this process, MID400W devices are able to achieve greater power efficiency, while maintaining their quality of performance.

MID400W devices can be used in a variety of application fields, from switching and logic circuits to PLCs and industrial automation. In switching applications, they are typically used in logic circuits, such as Boolean logic, to provide electrical isolation between two circuits. They are also used in PLCs and industrial process control systems to provide reliable, low-power electrical isolation between two or more interconnected devices.

The most common applications of MID400W devices are in automotive, aerospace, and military applications. They are used to provide reliable, low-power electrical isolation between components, while reducing crosstalk. In automotive safety systems, they are used to provide reliable, low-power electrical isolation between the circuits used to control the brakes and the accelerometer. In aerospace, they are used to provide reliable, low-power electrical isolation between the flight control systems and the flight data recorder. In military applications, they are used to provide reliable, low-power electrical isolation between the military radar system and the navigation computer.

MID400W devices offer a variety of benefits for application fields, such as reduced noise, reliability, and increased safety. They also offer higher system performance due to their high-efficiency operation. Since the part is composed of two components, the LED and the MOSFET, it can be used in a variety of ways, such as in logic and switching circuits, to provide reliable, low-power electrical isolation between two components or systems.

In summary, MID400W devices are a family of optical isolators intended for switching and logic circuits. They are designed for use in digital switching and logic circuits, providing an input/output voltage range of 10V to 24V, with current requirements of 8mA or 3.3mA. MID400W devices can be used in a variety of application fields, from switching and logic circuits to PLCs and industrial automation. They offer a variety of benefits, such as reduced noise, reliability, and increased safety, and higher system performance due to their high-efficiency operation.
