## CAD (KiCad official)

- Symbol: `RF05VA2STR`
- Footprint: `Diode_SMD:D_SOD-323F`
- 3D model: SOD-323FL (KiCad packages3D, STEP)
- 3D model files: `rf05va2str-etched.step` / `rf05va2str-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `rf05va2str.step` / `rf05va2str.glb` are the bare package body.
