Product details

Gate drive and switching: 20 nC total gate charge

A 100 kHz hard-switched application drawing 20 nC per cycle needs 2 mA average gate drive current — well within the capability of most driver ICs. The ±20 V gate-source rating gives headroom for ringing on long gate traces.

This makes the part suitable for under-hood automotive, downhole instrumentation, or power supplies that see sustained thermal cycling.

Package and thermal: D-Pak (TO-252) surface mount

For 45 W dissipation at the case, the board layout needs a minimum of 1 square inch of 2 oz copper on the drain plane to keep junction temperature within limits. The tape-and-reel option (TR suffix) is the standard production format; cut-tape (CT) is available for prototyping.

Frequently asked questions

What is a suitable replacement for IRFR024NTRPBF?

The IPD50R950CEAUMA1 is a different-class part (500 V, 950 mOhm, CoolMOS™ CE) and is not a functional replacement. For a drop-in alternative, look for an N-channel MOSFET in D-Pak with 55 V Vdss, 17 A Id, and 75 mOhm Rds(on) at 10 V.

Is IRFR024NTRPBF compatible with IRFR024N?

The IRFR024NTRPBF is the tape-and-reel packaged variant of the IRFR024N. The die and electrical specifications are identical — the suffix 'TRPBF' indicates tape-and-reel packaging and RoHS compliance. They are functionally compatible.
