## CAD (KiCad official)

- Symbol: `GS8M`
- Footprint: `Diode_SMD:D_SMC`
- 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
- 3D model files: `gs8m-etched.step` / `gs8m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gs8m.step` / `gs8m.glb` are the bare package body.
