# DSK320

**FUXINSEMI** · Schottky Diodes · SOD-123

DSK320 from FUXINSEMI, in a SOD-123. 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, marked by the color band on the package; DSK320 blocks up to VRRM/VDC of 200V with 3.0A average forward current. |
| 2 | A | passive | Anode; DSK320 has a maximum forward voltage of 0.92V at 3.0A and a peak surge current of 60.0A (8.3ms half sine-wave). |

## CAD (KiCad official)

- Symbol: `DSK320`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `dsk320-etched.step` / `dsk320-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dsk320.step` / `dsk320.glb` are the bare package body.
