540 nC gate charge — driver current budget
Total gate charge is 540 nC at 10 V. For a switching frequency of 20 kHz, the average gate drive current needed is 540 nC × 20 kHz = 10.8 mA, but the peak current during the Miller plateau determines the driver's instantaneous capability.
TO-247AC through-hole — thermal and mechanical fit
Housed in a TO-247-3 (TO-247AC) through-hole package, this part dissipates up to 520 W at the case. The through-hole leads need a drilled PCB or a heatsink with screw terminals — not a surface-mount reflow step.
