**Littelfuse** · TVS Diodes · SOD-123FL

SMF6.0A from Littelfuse, in a SOD-123FL. Symbol, footprint and 3D model are the ones used on Adom board designs (KiCad official libraries). Pin functions are extracted from the manufacturer datasheet with page references.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode; the color band denotes the cathode (uni-directional parts). [datasheet p.5] |
| 2 | A | passive | Anode; the terminal opposite the color band. [datasheet p.5] |

## CAD

- Symbol: `smf6-0a` (source library `Device:D_Zener_Filled`)
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model path in footprint: `${KICAD10_3DMODEL_DIR}/Diode_SMD.3dshapes/D_SOD-123F.step`
- 3D files: `smf6-0a-etched.step` / `smf6-0a-etched.glb` carry the MPN etch as a separate `Adom.LaserEtch` part; `smf6-0a.step` / `smf6-0a.glb` are the bare model.
- EAGLE/Fusion library: `smf6-0a.lbr` (adom-lbr)
