    MOSFET Output Optocouplers

    MOSFET output optocouplers, also known as optically coupled MOSFETs (OCMOSFETs), are a type of optocoupler that utilises a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) as the output device instead of a traditional phototransistor.

    Benefits of MOSFET Output Optocouplers:

    • Higher Output Current - enables them to drive larger loads such as relays, motors, and solenoid valves directly, eliminating the need for additional driver transistors.
    • AC/DC Compatibility
    • Faster Switching Speeds - MOSFETs can potentially offer faster switching speeds compared to phototransistors, which can be beneficial in high-frequency applications.

    In summary, MOSFET output optocouplers offer a compelling option when you need an optocoupler to handle higher currents, control AC signals, or achieve faster switching speeds. They are particularly valuable in applications involving driving power loads and high-frequency signal transmission.
