# HX3407

**HX hengjiaxing** · MOSFETs · SOT-23-3L

HX3407 from HX hengjiaxing, in a SOT-23-3L. 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; gate-source voltage limited to ±20 V, threshold VGS(th) -1.0 V min to -2.2 V max at ID=-250µA. |
| 2 | S | passive | Source of the P-channel MOSFET; drain-source voltage rating is -30 V and continuous drain current is -4 A at TC=25°C. |
| 3 | D | passive | Drain of the P-channel MOSFET; VDS = -30 V, ID = -4 A continuous, pulsed drain current -16 A. |

## CAD (KiCad official)

- Symbol: `HX3407`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3L (KiCad packages3D, STEP)
- 3D model files: `hx3407-etched.step` / `hx3407-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hx3407.step` / `hx3407.glb` are the bare package body.
