## CAD (KiCad official)

- Symbol: `ER1Q-LTP`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: DO-214AA(SMB) (KiCad packages3D, STEP)
- 3D model files: `er1q-ltp-etched.step` / `er1q-ltp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `er1q-ltp.step` / `er1q-ltp.glb` are the bare package body.
