# TF3407

**TF** · MOSFETs · SOT-23

TF3407 from TF, 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 P-channel MOSFET; gate-source voltage is rated ±20 V (VGS). |
| 2 | SOURCE | passive | Source terminal of the P-channel MOSFET; drain-source voltage is rated -30 V (VDS). |
| 3 | DRAIN | passive | Drain terminal of the P-channel MOSFET; continuous drain current is -4.1 A and pulsed drain current is -20 A (IDM). |

## CAD (KiCad official)

- Symbol: `TF3407`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `tf3407-etched.step` / `tf3407-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tf3407.step` / `tf3407.glb` are the bare package body.
