Product details

Gate charge and switching speed — the driver budget

Total gate charge is 270 nC at 10 V, with an input capacitance of 10150 pF at 25 V drain-source. That Qg tells you the gate-driver current needed for a target frequency: at 100 kHz switching, the average gate current is 27 mA, well within a standard driver's capability. The 6 V and 10 V drive voltage levels let you trade Rds(on) against gate-drive loss — 10 V gives the lowest on-resistance, 6 V reduces driver dissipation at the cost of higher Rds(on).

D2Pak rework — the tab is the thermal path

The TO-263-3 (D2Pak) surface-mount package has a large exposed drain tab that carries the bulk of the heat. The 290 W power dissipation rating at case temperature assumes the tab is soldered to a substantial copper pour — a two-layer board with a small pad will derate that figure significantly. Rework: the tab's thermal mass means a hot-air station needs a preheat plate under the board to avoid lifting the pad when the tab wets.

ROHS3 compliant. No official successor or second-source cross-reference is listed, so the BOM relies on this single source — budget for a qualified alternate if dual-sourcing is required.
