## CAD (KiCad official)

- Symbol: `E1J-TD`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123FL (KiCad packages3D, STEP)
- 3D model files: `e1j-td-etched.step` / `e1j-td-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `e1j-td.step` / `e1j-td.glb` are the bare package body.
