Gate drive and switching budget
The NP15P04SLG-E1-AY: NP15P04SLG--AY gate threshold voltage is 2.5 V max at 250 µA drain current, and the recommended drive voltage spans 4.5 V to 10 V. Total gate charge is 23 nC at 10 V, and input capacitance is 1100 pF at 10 V drain-source.
Thermal limits and package reality
Maximum junction temperature is 175 °C, with power dissipation rated at 1.2 W in still air at the tab (ambient) and 30 W when the case is held at 25 °C — the DPak tab must be soldered to a sufficient copper area on the PCB to keep the junction below the derating curve.
