**hongjiacheng** · MOSFETs · SOT-23

HL3401 from hongjiacheng, 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 of the P-channel MOSFET, rated for a gate-source voltage VGS of ±12 V. |
| 2 | S | passive | Source of the P-channel MOSFET; the maximum body-diode continuous current is -4.4 A. |
| 3 | D | passive | Drain of the P-channel MOSFET, rated for VDS = -30 V, continuous drain current ID = -4.4 A and pulsed drain current IDM = -17 A. |

## CAD (KiCad official)

- Symbol: `HL3401`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `hl3401-etched.step` / `hl3401-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hl3401.step` / `hl3401.glb` are the bare package body.
