# FDN358P

**UMW** · MOSFETs · SOT-23

FDN358P from UMW, in a SOT-23. 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 terminal of the P-channel MOSFET; gate-source voltage is rated ±20 V (VGSS) and the gate threshold VGS(th) is specified between -1 V and -3 V. |
| 2 | S | passive | SOURCE terminal of the P-channel MOSFET; the maximum continuous drain-source diode forward current is -0.42 A (IS). |
| 3 | D | passive | DRAIN terminal of the P-channel MOSFET; drain-source voltage is rated -30 V (VDSS) with continuous drain current of -1.5 A. |

## CAD (KiCad official)

- Symbol: `FDN358P`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `fdn358p-etched.step` / `fdn358p-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `fdn358p.step` / `fdn358p.glb` are the bare package body.
