For a 100 kHz switching frequency, the average gate-drive current needed is 60 nC × 100 kHz = 6 mA — well within a standard gate-driver IC's capability. The 1720 pF input capacitance at 25 V drain-source gives a sense of the switching energy per cycle; the driver must source and sink that charge through the gate loop inductance without ringing. ## Temperature range — rated for the harsh stuff Junction temperature range is -55°C to 175°C, which puts this part in the military/industrial temperature grade. That 175°C ceiling suits engine-bay electronics, downhole tools, and avionics power stages where ambient heat pushes junction temperatures past the usual 150°C limit. ## Package and mounting Surface-mount D-Pak (TO-252) with two leads and a tab. Rework is straightforward with hot air: preheat the board to 100°C, hit the tab with 350°C air, lift when the solder flows. The tab orientation is marked by a chamfer on the package body — easy to see under magnification. ## Lifecycle — still in active production ROHS3 compliant.","metaTitle":"IRFR48ZTRPBF MOSFET N-CH 55V 42A DPAK, 11mOhm Rds(on)","metaDescription":"IRFR48ZTRPBF N-channel HEXFET MOSFET, 55V Vdss, 42A Id, 11mOhm Rds(on) at 10V.
