## CAD (KiCad official)

- Symbol: `MUR1660`
- Footprint: `Package_TO_SOT_THT:TO-220-2_Vertical`
- 3D model: TO-220AC (KiCad packages3D, STEP)
- 3D model files: `mur1660-etched.step` / `mur1660-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mur1660.step` / `mur1660.glb` are the bare package body.
