# 3402

**HL** · MOSFETs · SOT-23

3402 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; gate-source voltage limited to ±12 V, threshold 0.5 V min to 1.4 V max at 250 μA. |
| 2 | S | passive | Source; connects to the body diode anode, and continuous drain current is 4.5 A at 25 °C. |
| 3 | D | passive | Drain; drain-source voltage rated 30 V, continuous current 4.5 A at 25 °C and pulsed 16.4 A. |

## CAD (KiCad official)

- Symbol: `3402`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `3402-etched.step` / `3402-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `3402.step` / `3402.glb` are the bare package body.
