75 V, 82 A N-channel HEXFET in D2PAK
The 13 mOhm maximum on-resistance at 43 A with a 10 V gate drive keeps conduction losses manageable in high-current switching circuits — think DC-DC converters, motor drives, battery management, and automotive load switching.
175 °C junction — the real thermal headroom
That 175 °C Tj max is the absolute limit — not a continuous operating target — but it gives margin for transient overloads in high-ambient environments like under-hood automotive, industrial motor compartments, or sealed power supplies. The 230 W power dissipation at Tc is a package-level number; real dissipation depends on the board's ability to sink heat from the D2PAK tab.
Gate charge and input capacitance — the switching cost
For new designs or ongoing production, the supply channel is stable through standard distribution.
