## CAD (KiCad official)

- Symbol: `P3100SC`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
- 3D model files: `p3100sc-etched.step` / `p3100sc-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `p3100sc.step` / `p3100sc.glb` are the bare package body.
