# DSK24L

**Leiditech** · Schottky Barrier Diodes (SBD) · SOD-123FL

DSK24L from Leiditech, in a SOD-123FL. 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, the end marked by the color band on the SOD-123FL Schottky rectifier (2.0 A average rectified current, DSK24L rated 40 V repetitive peak reverse). |
| 2 | A | passive | Anode of the SOD-123FL Schottky rectifier, opposite the color-banded cathode end. |

## CAD (KiCad official)

- Symbol: `DSK24L`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `dsk24l-etched.step` / `dsk24l-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dsk24l.step` / `dsk24l.glb` are the bare package body.
