55V, 17A N-channel HEXFET in DPAK — what it is and where it fits
The IRFR024NTRLPBF is an N-channel power MOSFET from the HEXFET series, rated for 55 V drain-source voltage and 17 A continuous drain current at 25 °C case temperature. It comes in a DPAK (TO-252) surface-mount package, a common footprint for medium-current switching and load management on compact PCBs. The 75 mOhm maximum on-resistance at 10 V gate drive and 10 A drain current defines the conduction loss for a typical design point. With a junction temperature range of -55 °C to 175 °C, it handles the thermal cycling found in automotive under-hood, industrial motor drives, and outdoor telecom power supplies.
75 mOhm Rds(on) — what it means for the BOM
At 10 A and 10 V gate drive, the 75 mOhm max on-resistance is within the 45 W package dissipation limit at case temperature.
Active lifecycle — no LTB risk
It is ROHS3 compliant, which covers the lead-free and RoHS exemption requirements for most commercial and industrial builds. For a BOM line that needs a proven 55 V N-channel switch in DPAK, this part is a safe selection for both new designs and ongoing production.
