D4184-VB from VBsemi Elec, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate of the N-channel MOSFET, rated for a gate-source voltage of ±25 V (absolute maximum) with VGS = 10 V and 4.5 V used for RDS(on) specification.
2 D passive Drain of the N-channel MOSFET, rated 40 V drain-source breakdown (VGS = 0 V, ID = 250 µA) with continuous drain current of 85 A at TC = 25 °C (package limitation current 110 A).
3 S passive Source of the N-channel MOSFET, with continuous source-drain diode current IS of 110 A at TC = 25 °C and operating junction and storage temperature range of -55 °C to 150 °C.
