SI3134KEA-TP from MCC Micro Commercial Components, in a SOT-523. 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 terminal of the N-channel MOSFET; gate threshold VGS(th) is 0.5 V min, 0.7 V typ, 1.1 V max at VDS=VGS, ID=250µA. |
| 2 | S | passive | Source terminal; body diode forward voltage VSD is 1.2 V at VGS=0V, IS=500mA. |
| 3 | D | passive | Drain terminal; drain-source breakdown voltage V(BR)DSS is 20 V minimum at VGS=0V, ID=250µA. |

## CAD (KiCad official)

- Symbol: `SI3134KEA-TP`
- Footprint: `Package_TO_SOT_SMD:SOT-523`
- 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `si3134kea-tp-etched.step` / `si3134kea-tp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `si3134kea-tp.step` / `si3134kea-tp.glb` are the bare package body.
