Product details

55 V, 30 A N-channel HEXFET — switching and conduction loss budget

Gate charge totals 92 nC at 10 V, which means a 1 A gate driver can charge the gate in about 92 ns — practical for switching frequencies up to the low tens of kHz before driver current becomes the limiting factor. Input capacitance is 1870 pF at 25 V drain bias.

175 °C junction — under-hood and high-ambient margin

That extra 25 °C headroom matters in under-hood motor drives, engine bay solenoid drivers, and industrial power supplies where ambient air can hit 105 °C and the junction sees the ripple. The D-Pak (TO-252) surface-mount package with a single tab for the drain connection requires a copper pad on the PCB for thermal management — the 120 W dissipation rating assumes the tab is soldered to a large copper area.

Active production — no last-time-buy pressure

ROHS3 compliant.

Frequently asked questions

What is the Rds(on) of IRLR3915TRPBF?

Maximum on-resistance is 14 mOhm at 30 A drain current with 10 V gate-to-source drive. At 5 V drive the Rds(on) will be higher — the datasheet specifies drive voltage for max Rds(on) as 5 V and 10 V.

What is the gate charge of IRLR3915TRPBF?

Total gate charge is 92 nC maximum at 10 V gate drive. This is the charge the gate driver must supply to switch the FET on; a 1 A driver can deliver 92 nC in about 92 ns.

Is IRLR3915TRPBF RoHS compliant?

Yes, it is ROHS3 compliant per the listing.
