**STMicroelectronics** · MOSFETs · D2PAK

STB75NF20 from STMicroelectronics, in a D2PAK. 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 control input of the N-channel MOSFET, with absolute maximum gate-source voltage of ±20 V and threshold VGS(th) of 2 V min to 4 V max at ID = 250 µA. |
| 2 | D | passive | Drain terminal (also the tab) of the N-channel MOSFET, rated 200 V VDS and 75 A continuous drain current at TC = 25°C. |
| 3 | S | passive | Source terminal of the N-channel MOSFET, carrying up to 75 A continuous current at TC = 25°C. |

## CAD (KiCad official)

- Symbol: `STB75NF20`
- Footprint: `Package_TO_SOT_SMD:TO-263-2`
- 3D model: D2PAK (KiCad packages3D, STEP)
- 3D model files: `stb75nf20-etched.step` / `stb75nf20-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `stb75nf20.step` / `stb75nf20.glb` are the bare package body.
