# 3407

**HL** · MOSFETs · SOT-23

3407 from HL, 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; the absolute maximum gate-source voltage is VGS ±20 V. |
| 2 | S | passive | Source of the P-channel MOSFET; the datasheet gives no separate pin-specific limit, and the device ratings are VDS -30 V and continuous ID -4.5 A at TA=25℃ (page 1). |
| 3 | D | passive | Drain of the P-channel MOSFET; the absolute maximum drain-source voltage is VDS -30 V, with continuous drain current ID -4.5 A at TA=25℃ and -3.6 A at TA=70℃. |

## CAD (KiCad official)

- Symbol: `3407`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `3407-etched.step` / `3407-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `3407.step` / `3407.glb` are the bare package body.
