## CAD (KiCad official)

- Symbol: `BAT48ZFILM`
- Footprint: `Diode_SMD:D_SOD-123`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `bat48zfilm-etched.step` / `bat48zfilm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bat48zfilm.step` / `bat48zfilm.glb` are the bare package body.
