## CAD (KiCad official)

- Symbol: `PMM1W5V6`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `pmm1w5v6-etched.step` / `pmm1w5v6-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pmm1w5v6.step` / `pmm1w5v6.glb` are the bare package body.
