## CAD (KiCad official)

- Symbol: `PTVS26VP1UP`
- Footprint: `Diode_SMD:D_SOD-128`
- 3D model: SOD-128 (KiCad packages3D, STEP)
- 3D model files: `ptvs26vp1up-etched.step` / `ptvs26vp1up-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ptvs26vp1up.step` / `ptvs26vp1up.glb` are the bare package body.
