# 3400Q

**HL** · MOSFETs · SOT-89-3L

3400Q from HL, in a SOT-89-3L. 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 ±12 V, threshold 0.5 V min, 0.9 V typ, 1.4 V max at 250 µA. |
| 2 | D | passive | Drain, also connected to the exposed tab; drain-source voltage 30 V max, continuous drain current 7.0 A at TA=25 °C. |
| 3 | S | passive | Source; body diode continuous forward current 7.0 A max and forward voltage 1.2 V max. |

## CAD (KiCad official)

- Symbol: `3400Q`
- Footprint: `Package_TO_SOT_SMD:SOT-89-3`
- 3D model: SOT-89-3L (KiCad packages3D, STEP)
- 3D model files: `3400q-etched.step` / `3400q-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `3400q.step` / `3400q.glb` are the bare package body.
