30 V, 5 A P-Channel — load-switch and power-path fit
It comes in an 8-SOIC package and is intended for load switching, battery protection, and power-rail OR-ing in portable and industrial gear where a P-Channel simplifies the high-side drive.
56 mOhm Rds(on) — conduction loss at the BOM level
That figure sets the conduction loss floor for a 5 A load: about 1.4 W at max current, which the 2.7 W package dissipation (Ta) can handle with adequate copper area on the PCB.
6 nC gate charge — direct GPIO drive possible
Total gate charge at 4.5 V is 6 nC. That is low enough to switch from a microcontroller GPIO through a series resistor, without a dedicated gate driver IC. Input capacitance Ciss is 639 pF at 25 V drain bias, which keeps switching losses modest in the tens-of-kHz range. For higher frequencies, the gate drive source impedance matters more than the charge number alone.
