Why is an N-channel MOSFET preferred over a P-channel MOSFET?

Why is an N-channel MOSFET preferred over a P-channel MOSFET? Correct Answer Because it allows fast switching

  • The mobility of electrons, which are carriers in the case of an n-channel device, is greater than that of holes, which are the carriers in the p-channel device.
  • Thus an n-channel device is faster than a p-channel device.
  • The N-channel transistor has lower on-resistance and gate capacitance for the same die area.
