## CAD (KiCad official)

- Symbol: `PJE8405_R1_00001`
- Footprint: `Package_TO_SOT_SMD:SOT-523`
- 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `pje8405-r1-00001-etched.step` / `pje8405-r1-00001-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pje8405-r1-00001.step` / `pje8405-r1-00001.glb` are the bare package body.
