**YFW** · MOSFETs · SOT23-3L

YFW3404MI from YFW, in a SOT23-3L. 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; absolute maximum gate-source voltage is ±20 V with a threshold VGS(th) of 1.2 V min to 2.5 V max at VDS=VGS, ID=250uA. |
| 2 | S | passive | Source; continuous source current is 5.8 A max with a body diode forward voltage of 1.2 V max at IS=1A. |
| 3 | D | passive | Drain; drain-source voltage is 30 V max with continuous drain current of 8 A at TA=25°C and pulsed drain current of 20 A. |

## CAD (KiCad official)

- Symbol: `YFW3404MI`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT23-3L (KiCad packages3D, STEP)
- 3D model files: `yfw3404mi-etched.step` / `yfw3404mi-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `yfw3404mi.step` / `yfw3404mi.glb` are the bare package body.
