The most commonly used type of MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is the
N-channel MOSFET.
Here's why:
- Higher Electron Mobility: N-channel MOSFETs generally have better performance because electrons (the charge carriers) have higher mobility than holes (used in P-channel MOSFETs). This leads to faster switching speeds and lower on-resistance, making them more efficient.
- Better Efficiency: The N-channel MOSFET typically provides lower resistance when conducting (lower R_DS(on)), which means less power loss and better overall efficiency.
- Cost-Effective: N-channel MOSFETs are cheaper and more widely available than their P-channel counterparts, so they are the default choice in most applications.
They are used in a wide range of applications like power electronics, motor control, and digital circuits.
