5 mOhm at 10 V — the conduction-loss anchor for a P-channel switch
The UPA2735GR-E1-AX: The headline Rds(on) of 5 mOhm max at Vgs = 10 V and Id = 16 A sets the conduction loss floor — at 16 A the dissipation is 1.28 W, well inside the 2.5 W package limit at 25 °C, leaving thermal headroom for derating at elevated ambient.
Gate charge and drive voltage — sizing the gate driver
Total gate charge Qg is 195 nC at Vgs = 10 V. The drive voltage range spans 4.5 V to 10 V for Rds(on) optimisation.
Input capacitance and switching speed
Input capacitance Ciss is 6250 pF at Vds = 10 V. Combined with the Qg of 195 nC, the Miller plateau duration is typical for a 30 V P-channel in this die size.
