# STD17NF25

**STMicroelectronics** · MOSFET · DPAK

STD17NF25 from STMicroelectronics, in a DPAK. 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 for device switching with ±20 V absolute maximum gate-source voltage and 2 to 4 V gate threshold voltage. |
| 2 | D | power_in | Drain terminal with 250 V maximum drain-source voltage rating, 17 A continuous drain current at 25°C (10 A at 100°C), 140 to 165 mΩ on-resistance, connected to metal TAB for thermal dissipation. |
| 3 | S | power_out | Source terminal providing current return path with rating supporting 10 A continuous current at 100°C junction temperature. |

## CAD (KiCad official)

- Symbol: `STD17NF25`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: DPAK (KiCad packages3D, STEP)
- 3D model files: `std17nf25-etched.step` / `std17nf25-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `std17nf25.step` / `std17nf25.glb` are the bare package body.
