P-channel power switch in a D-Pak
The IRFR5305TRPBF is a P-Channel enhancement-mode MOSFET from Infineon's HEXFET® series, housed in a D-Pak (TO-252) surface-mount package.
Total gate charge is 63 nC at 10 V — a 10 V gate-drive rail is needed to hit the rated Rds(on). Input capacitance is 1200 pF at 25 V Vds. The ±20 V Vgs(max) rating gives margin for gate-drive overshoot in hard-switched topologies.
Thermal and mechanical fit
The D-Pak (TO-252) footprint shares the same land pattern as the standard DPAK, so a board already laid out for an N-channel DPAK can accept this P-channel part with only a gate-drive polarity change.
It is ROHS3 compliant.
