P-Channel power switch for 24 V / 48 V rails
The NP36P06KDG-E1-AY: P-Channel MOSFET, 60 V drain-source, 36 A continuous drain, 29.5 mOhm Rds(on) at 10 V gate drive.
Thermal and package reality
The TO-263-3 (D²Pak) surface-mount package exposes a large copper tab on the bottom — the thermal pad. Power dissipation is rated at 1.8 W in still air (Ta) and 56 W when the tab is soldered to a sufficient board copper area (Tc).
Gate drive and switching behaviour
Input capacitance is 3100 pF at 10 V drain-source; total gate charge is 54 nC at 10 V.
