## CAD (KiCad official)

- Symbol: `ES8JH`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: SMC (KiCad packages3D, STEP)
- 3D model files: `es8jh-etched.step` / `es8jh-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `es8jh.step` / `es8jh.glb` are the bare package body.
