For a 100 kHz switching frequency the average gate-drive current is 8.9 mA — a standard gate-driver IC like the IR2110 or a half-bridge driver handles that without an external booster. The 2950 pF input capacitance at 25 V drain-source gives the driver a capacitive load to charge each cycle; the driver's peak current rating should exceed 1 A to keep the switching transition under 100 ns. ## Thermal envelope and package Maximum power dissipation is 140 W at the case, but the junction-to-ambient thermal resistance in the D-Pak (TO-252) surface-mount package sets the real limit — expect about 50 °C/W on a standard FR-4 footprint with 1 oz copper. ## Lifecycle and compliance ROHS3 compliant. No official second-source cross-reference is listed, but the D-Pak footprint is standard across the industry; a functional alternative would need to match the 40 V, 5.5 mOhm, and 89 nC gate charge profile.","metaTitle":"IRFR4104TRPBF N-Channel MOSFET, 40 V, 42 A, 5.5 mOhm, D-Pak","metaDescription":"IRFR4104TRPBF HEXFET N-channel MOSFET, 40 V drain-source, 42 A continuous, 5.5 mOhm Rds(on) at 10 V.
