800 V CoolMOS™ — the high-voltage switching workhorse
The TO-220-3 through-hole package suits designs where the heatsink mounts directly to the tab and the board sees the mechanical load.
280 mOhm Rds(on) — conduction loss budget for 7.2 A
At 7.2 A drain current and 10 V gate drive, the maximum on-resistance is 280 mOhm. That translates to about 14.5 W conduction loss at 7.2 A — within the 101 W power dissipation limit at the case, but the junction-to-case thermal path needs a heatsink sized for the duty cycle. The 36 nC total gate charge at 10 V means the gate driver sees a moderate capacitive load; a 1 A driver switches the gate in roughly 36 ns, which keeps cross-conduction losses low in a hard-switched topology.
Temperature range and thermal design
The 101 W maximum power dissipation at the case assumes an infinite heatsink; real-world designs derate that figure per the thermal resistance of the chosen heatsink and the ambient temperature. The 3.5 V maximum gate threshold at 360 µA drain current means the device turns on reliably with a 5 V gate drive signal, though the 10 V drive voltage is needed to reach the rated on-resistance.
