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. The 63 nC total gate charge at 10 V is the figure to budget in the gate-driver's peak current capability.

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.
