## CAD (KiCad official)

- Symbol: `SDT30100CT`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220-3 (KiCad packages3D, STEP)
- 3D model files: `sdt30100ct-etched.step` / `sdt30100ct-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sdt30100ct.step` / `sdt30100ct.glb` are the bare package body.
