Total gate charge is 29.5 nC at 10 V, with an input capacitance of 1000 pF at 25 V drain. A 29.5 nC gate charge means a 10 V gate driver delivering 1 A can switch the FET in about 30 ns — fast enough for a 100 kHz hard-switching converter, but the Miller plateau will stretch the turn-off if the gate-drive loop inductance isn't kept under 10 nH. ## Package and thermal budget Housed in a D²PAK (TO-263) surface-mount package with a single drain tab. The 110 W power dissipation at case temperature is the absolute ceiling — in a real board with 1 oz copper and minimal heatsinking, derate to about 40 W continuous before the junction hits 175°C.","metaTitle":"STB18NF25 MOSFET, N-Channel 250V 17A, AEC-Q101, D2PAK","metaDescription":"STB18NF25 N-channel MOSFET, 250V Vdss, 17A Id, 165mOhm Rds(on) at 10V.
