AN804 - P-Channel MOSFET
AN804 Vishay Siliconix P-Channel MOSFETs, the Best Choice for High-Side Switching Historically, p-channel FETs were not considered as useful as their n-channel counterparts.
The higher resistivity of p-type silicon, resulting from its lower carrier mobility, put it at a disadvantage compared to n-type silicon.
Getting n-type performance out of p-type FETs has meant larger area geometries with correspondingly higher inter-electrode capacitances.
Consequently, a truly complementary pair
