## CAD (KiCad official)

- Symbol: `BAT54SW_R1_00001`
- Footprint: `Package_TO_SOT_SMD:SOT-323_SC-70`
- 3D model: SOT-323-3 (KiCad packages3D, STEP)
- 3D model files: `bat54sw-r1-00001-etched.step` / `bat54sw-r1-00001-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bat54sw-r1-00001.step` / `bat54sw-r1-00001.glb` are the bare package body.
