Gate charge and switching speed
The SPD03N60C3ATMA1: Total gate charge is 17 nC at 10 V Vgs. Input capacitance is 400 pF at 25 V drain-source.
Thermal and package realities
Maximum power dissipation is 38 W at case temperature Tc. The TO-252-3 package relies on the PCB copper area under the tab for heat spreading.
