Advantages

a) It is a voltage controlled device so easy to drive.

b) Requires negligible power to hold it in the ON state.

c) The gate drive circuitry is less complex & less costly.

d) Fast switching speed.

e) No additional Circuit is required for commutation.

f) No secondary breakdown

g) Small Size and less expensive.

Disadvantages

a) The on state voltage across a power MOSFET is high. Therefore the on-state power dissipation is very high, as compared to that of a power transistor.

b) Power MOSFETs need special care while handling otherwise they can damaged due to static electricity.
