Product details

Through-hole IPAK — thermal and mounting

Housed in the TO-251AA (IPAK) package with short leads, this is a through-hole part intended for board-level mounting where a surface-mount reflow profile is not available or where the PCB requires mechanical retention.

Gate drive and switching parameters

The gate threshold voltage is specified at 4 V maximum with 250 µA drain current; the recommended drive voltage for minimum on-resistance is 10 V. Input capacitance is 1200 pF at 25 V drain-source — a moderate capacitance that keeps gate-drive losses manageable at switching frequencies typical of load-switch or low-side P-Channel applications. The maximum gate-source voltage is ±20 V, so a 10 V drive rail leaves margin.

Frequently asked questions

Is IRFU5305PBF RoHS compliant?

Yes, it is ROHS3 compliant, meeting the current EU restriction directive.

Can IRFU5305PBF replace IRFU5305?

The IRFU5305PBF is the lead-free (PbF) suffix variant of the original IRFU5305. The electrical ratings — 55 V Vdss, 31 A Id, 65 mOhm Rds(on) — are identical, and the package (IPAK TO-251AA) is the same. The PBF suffix indicates ROHS3 compliance; it is a drop-in replacement for the non-PBF version in designs requiring lead-free assembly.
