# FDN337N-GK

**GOODWORK** · MOSFETs · SOT-23

FDN337N-GK from GOODWORK, 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 | GATE | input | Gate terminal of the N-channel MOSFET, rated for a gate-source voltage VGS of ±12 V, and used as a voltage-controlled small-signal switch. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET, the reference for VGS and for the drain current ratings (continuous ID 5.8 A, pulsed IDM 30 A). |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET, rated for a drain-source voltage VDS of 30 V with 5.8 A continuous drain current. |

## CAD (KiCad official)

- Symbol: `FDN337N-GK`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `fdn337n-gk-etched.step` / `fdn337n-gk-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `fdn337n-gk.step` / `fdn337n-gk.glb` are the bare package body.
