## CAD (KiCad official)

- Symbol: `SC92F8372M20U`
- Footprint: `Package_SO:SOP-20_7.5x12.8mm_P1.27mm`
- 3D model: SOP-20-300mil, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 2.65 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `sc92f8372m20u-etched.step` / `sc92f8372m20u-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sc92f8372m20u.step` / `sc92f8372m20u.glb` are the bare package body.
