## CAD (KiCad official)

- Symbol: `SL4041`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3 (KiCad packages3D, STEP)
- 3D model files: `sl4041-etched.step` / `sl4041-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sl4041.step` / `sl4041.glb` are the bare package body.
