## CAD (KiCad official)

- Symbol: `PESDU2481D1F`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `pesdu2481d1f-etched.step` / `pesdu2481d1f-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pesdu2481d1f.step` / `pesdu2481d1f.glb` are the bare package body.
