# YFW50N10AD

**YFW** · MOSFETs · TO-252

YFW50N10AD from YFW, 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; gate-source voltage is rated at ±20 V maximum, with a threshold of 1 V to 3 V at ID = 250 µA. |
| 2 | D | passive | Drain, also the exposed tab; drain-source voltage is rated at 100 V and continuous drain current at 50 A. |
| 3 | S | passive | Source; connects to the body diode and carries the 50 A continuous drain current return. |

## CAD (KiCad official)

- Symbol: `YFW50N10AD`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `yfw50n10ad-etched.step` / `yfw50n10ad-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `yfw50n10ad.step` / `yfw50n10ad.glb` are the bare package body.
