At 1.9 A and 160 mOhm, the conduction loss is about 580 mW — within the 1 W power dissipation limit at 25 °C ambient, but the SOT-223's thermal resistance means the PCB copper area under the tab sets the real current ceiling. 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.
