## Materials and finish

As the datasheet states them (page.json `metadata.appearance`; the 3D model's colours follow it).

| Part | Material | Colour / plating | Datasheet says | Page |
|---|---|---|---|---|
| contacts |  | tin | ● Terminals: Tin plated leads, solderable per J-STD￾002 and JESD22-B102 ● Polarity:Color band denotes cathode end | 1 |

## CAD (KiCad official)

- Symbol: `GR3D`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: SMC (KiCad packages3D, STEP)
- 3D model files: `gr3d-etched.step` / `gr3d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gr3d.step` / `gr3d.glb` are the bare package body.
