    Why is the Power rating of a power MOSFET low?
    Why is the switching frequency of a power BJT low?:confused:

    This is a stupid question, no reference to anything.... what is low? power mosfets can handle a lot of power. Up to 20-30 amps or more if needed, What do you want ? a welding machine ?

    Hello,

    Take a look at the attached PDF about the difference between Mosfet and IGBT.
