Product details

5.4 nC gate charge — fast switching without a big driver

Total gate charge is 5.4 nC at 10 V. That is low enough that a standard GPIO pin with a series resistor can drive it at moderate frequency — no dedicated gate driver IC needed for sub-500 kHz switching. The 430 pF input capacitance at 10 V drain-source confirms the light load on the drive circuit.

That covers avionics bay, outdoor telecom cabinet, and engine-compartment environments. Power dissipation is limited to 1.25 W at 25°C ambient in the SOT-23 — derate above that, and keep the copper pad area generous on the PCB.

SOT-23 — reworkable, but watch the thermal pad

The SOT-23 package (TO-236 / SC-59 variant) is a three-lead surface-mount part. It reworks cleanly under hot air — the small body heats fast, and the leads are on the long sides so alignment is straightforward. No hidden thermal pad underneath, so the board copper is what pulls heat away.

Frequently asked questions

What is the Rds(on) of IRFML8244TRPBF?

The maximum Rds(on) is 24 mOhm at a drain current of 5.8 A and a gate-source voltage of 10 V. That is the on-resistance at the rated continuous current — conduction loss is I²R at that operating point.

Is IRFML8244TRPBF RoHS compliant?

Yes, it is ROHS3 compliant — no restricted substances above the threshold limits. Lead-free soldering profiles apply.

What is the drain current rating of IRFML8244TRPBF?

Continuous drain current is 5.8 A at 25°C ambient, limited by the 1.25 W power dissipation in the SOT-23 package. Derate for higher ambient temperature.

What is the gate charge of IRFML8244TRPBF?

Total gate charge is 5.4 nC at a gate voltage of 10 V. That is a light load on the gate drive — suitable for direct drive from a logic output or a small gate driver.
