Product details

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.

Frequently asked questions

Is IRFR5305TRPBF a direct replacement for IRFR5305?

The IRFR5305TRPBF is the tape-and-reel variant of the base IRFR5305. The die, package, and electrical ratings are identical; the suffix indicates the reel packaging format. No additional qualification or re-spin is needed when substituting one for the other on the BOM.

What is the Rds(on) of IRFR5305TRPBF?

Maximum on-resistance is 65 mOhm at 16 A drain current with 10 V gate-to-source drive. This is the spec to use for conduction-loss calculations at rated load.

Is IRFR5305TRPBF RoHS compliant?

Yes, the part is ROHS3 compliant, meaning it meets the EU RoHS directive with no exemptions for lead, mercury, cadmium, or other restricted substances.
