The 11 nC total gate charge at 10 V means a small gate-driver IC or even a GPIO with a series resistor can switch it at tens of kHz without excessive drive current. Input capacitance is 190 pF at 25 V Vds — low enough that switching losses stay modest up to a few hundred kHz, but the 1 W dissipation limit in free air will be the binding constraint before the gate charge becomes one. ## SOT-223 footprint — layout and thermal reality Operating junction temperature range is -55 to 150 °C, so it handles automotive under-hood ambient and industrial enclosures without derating the voltage or current ratings at the high end.","metaTitle":"IRFL014NTRPBF MOSFET, N-Channel 55V 1.9A SOT-223, Active","metaDescription":"IRFL014NTRPBF HEXFET N-Channel MOSFET, 55V Vdss, 1.9A Id, 160mOhm Rds(on) at 10V.
