## CAD (KiCad official)

- Symbol: `1PS70SB84`
- Footprint: `Package_TO_SOT_SMD:SOT-323_SC-70`
- 3D model: SOT-323 (KiCad packages3D, STEP)
- 3D model files: `1ps70sb84-etched.step` / `1ps70sb84-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `1ps70sb84.step` / `1ps70sb84.glb` are the bare package body.
