Product details

P-channel power switch for 100 V rails

The IRFP9140NPBF: The 117 mOhm maximum on-resistance at 13 A with 10 V gate drive sets the conduction loss floor for a high-side load switch or a P-channel half-bridge leg.

Through-hole mounting and thermal interface

The TO-247-3 (TO-247AC) package has a large exposed metal tab — intended for screw or clip attachment to a heatsink.

Temperature range and deployment envelope

The 175 °C Tj max gives extra headroom in a sealed enclosure or high-vibration environment where heatsinking is constrained.

Frequently asked questions

What is the equivalent of IRFP9140NPBF?

No direct pin-compatible second-source is listed. The IPD50R950CEAUMA1 is a different class — N-channel, 500 V, surface-mount DPAK — and is not a functional substitute for this P-channel 100 V through-hole MOSFET.

Is IRFP9140NPBF RoHS compliant?

Yes, it carries ROHS3 compliance status.

What does the 117 mOhm Rds(on) mean for my design?

At 13 A with 10 V gate drive, the 117 mOhm max on-resistance produces about 20 W conduction loss. This sets the heatsink requirement — a TO-247 bolted to a 2–3 °C/W heatsink keeps the junction below 125 °C at that current. Derate for higher ambient or reduced airflow.
