    Hari,

    Thanks for the question.
    In general the advantages of MOSFETs are that they have a faster switching speed. The bipolar is a device that is current controlled and as such the switching speed depends very much on the driver strength, whereas the MOSFET is a simpler voltage controlled device and the gates generally switch much faster. In addition the bipolar devices have a much longer turn off or current tail vs a MOSFET.

    Best Regards
