Gate charge and drive budget
Total gate charge is 14 nC at 10 Vgs. For a 100 kHz switching frequency, the gate driver must supply 1.4 mA average current; at 500 kHz that rises to 7 mA, still within the capability of a standard low-side driver.
Thermal limit in the SOT-223 footprint
Maximum power dissipation is 1 W at 25°C ambient, derated to zero at 150°C junction. The SOT-223 package relies on the PCB copper pad area under the tab for heat spreading — a 1-oz copper pour of at least 300 mm² keeps the junction below 125°C at 0.8 W continuous.
