600 V N-channel — where it lands in a power stage
The STP28N60DM2: It comes in a TO-220-3 through-hole package, which bolts to a heatsink or chassis for thermal management.
At 160 mOhm max with 10 V gate drive, the STP28N60DM2's on-resistance is competitive for a 600 V, 21 A class part in a TO-220. The 34 nC total gate charge at 10 V means a standard gate-driver IC (e.g., 1 A peak source/sink) can switch it at 100 kHz with under 4 mA average drive current — no external booster needed. Input capacitance is 1500 pF at 100 V drain-source, which keeps the Miller plateau manageable for a simple RC gate-drive network.
Thermal budget in a real enclosure
The 170 W maximum power dissipation at case temperature assumes an infinite heatsink — in practice, a TO-220 bolted to a 5 °C/W heatsink in still air at 50 °C ambient will dissipate about 20–25 W before the junction hits 125 °C. The 21 A continuous rating at 25 °C case derates to roughly 13 A at 100 °C case (following the typical 0.65× derating for a 100 °C rise).
