Product details

The 48 W package dissipation limit at case temperature gives thermal headroom for switching frequencies where switching losses stay low.

Gate charge and input capacitance — switching speed budget

Gate charge is 20 nC at 5 V gate drive, and input capacitance is 440 pF at 25 V drain-source. These numbers are moderate — the part switches cleanly in the tens to low hundreds of kHz range without excessive gate-drive power. The ±16 V maximum gate-source voltage allows robust gate drive without worrying about oxide breakdown.

The DPAK package is widely used and stocked across distribution.

Frequently asked questions

Is IRLR120NTRLPBF a direct replacement for IRLR120N?

The IRLR120NTRLPBF is the ROHS3-compliant, tape-and-reel variant of the IRLR120N. The suffix 'TRLPBF' indicates tape-and-reel packaging and lead-free / ROHS compliance. Electrically and mechanically it is the same die in the same DPAK package, so it is a direct drop-in replacement for the non-ROHS or bulk-packaged IRLR120N.

What is the closest pin-compatible alternative to IRLR120NTRLPBF in this component family?

Within the same HEXFET® family, the IRLR120N (non-ROHS, bulk) is pin-compatible and electrically identical. For a higher-current alternative in the same DPAK footprint, the IRLR2905 (60 V, 42 A) or IRLR7843 (30 V, 161 A) are pin-compatible but have different voltage and current ratings — verify your rail voltage and load before substituting.
