## CAD (KiCad official)

- Symbol: `STP6NK90Z`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220 (KiCad packages3D, STEP)
- 3D model files: `stp6nk90z-etched.step` / `stp6nk90z-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `stp6nk90z.step` / `stp6nk90z.glb` are the bare package body.
