The solid-state nature of the mosfet ensures a much longer operational lifespan with no physical wear. An n channel p channel mosfet configuration represents one of the most fundamental and widely used arrangements in modern power electronics and switching applications.
Effective Thermal Management Strategies for N-Channel and P-Channel MOSFETs
Conversely, a p-channel mosfet conducts when a negative gate-to-source voltage is applied, which is typically easier to achieve for low-side switching. Because the p-channel device typically has a lower electron mobility compared to its n-channel counterpart, it may exhibit higher resistance.
Furthermore, when configured correctly, these components exhibit a very low on-state resistance, which drastically reduces heat generation and energy dissipation. A lower Rds(on) value indicates better efficiency, as it minimizes the voltage drop and heat generation across the device during operation.

By arranging four mosfets into an H pattern, the system can reverse the polarity of the load voltage, allowing a motor to spin forward or backward.
