# SK4004WA

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

SK4004WA 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 | 1 | passive | Terminal labelled 1 in the top view of the 2-lead SOD-123FL outline; the datasheet does not state whether it is the anode or the cathode, and the diode symbol orientation on page 1 is the only polarity cue. The SK4004WA is rated 400 V repetitive peak reverse voltage and 1 A average forward current at Ta = 65 °C. |
| 2 | 2 | passive | Terminal labelled 2 in the top view of the 2-lead SOD-123FL outline; the datasheet does not state whether it is the anode or the cathode, and the diode symbol orientation on page 1 is the only polarity cue. The SK4004WA is rated 400 V repetitive peak reverse voltage and 1 A average forward current at Ta = 65 °C. |

## CAD (KiCad official)

- Symbol: `SK4004WA`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123F (KiCad packages3D, STEP)
- 3D model files: `sk4004wa-etched.step` / `sk4004wa-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sk4004wa.step` / `sk4004wa.glb` are the bare package body.
