# SK4002WA

**Shikues** · Diodes - General Purpose · SOD-123F

SK4002WA from Shikues, in a SOD-123F. 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 | K | passive | Cathode of the rectifier (reverse voltage 100 V VRRM for SK4002WA, 1 A average forward current); pin 1 on the top-view outline, polarity inferred from the symbol. |
| 2 | A | passive | Anode of the rectifier (1 A average forward current, 25 A peak surge, VF 1.1 V at 1 A); pin 2 on the top-view outline. |

## CAD (KiCad official)

- Symbol: `SK4002WA`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123F (KiCad packages3D, STEP)
- 3D model files: `sk4002wa-etched.step` / `sk4002wa-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sk4002wa.step` / `sk4002wa.glb` are the bare package body.
