# SK3134K

**Shikues** · MOSFETs · SOT-723

SK3134K from Shikues, in a SOT-723. 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 | GATE | input | MOSFET gate terminal; the datasheet gives a typical gate-source voltage rating of ±12 V (VGS), and the part is specified for low logic level gate drive. |
| 2 | SOURCE | passive | MOSFET source terminal; the body-diode forward voltage VSD is specified at 1.2 V max (IS = 0.15 A, VGS = 0 V). |
| 3 | DRAIN | passive | MOSFET drain terminal; the drain-source voltage rating is 20 V and the continuous drain current is 0.75 A (note 1: surface mounted on FR4 at minimum recommended pad size). |

## CAD (KiCad official)

- Symbol: `SK3134K`
- Footprint: `Package_TO_SOT_SMD:SOT-723`
- 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 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: `sk3134k-etched.step` / `sk3134k-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sk3134k.step` / `sk3134k.glb` are the bare package body.
