CAD (KiCad official)

  • Symbol: BAS20DW-7
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363 (KiCad packages3D, STEP)
  • 3D model files: bas20dw-7-etched.step / bas20dw-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas20dw-7.step / bas20dw-7.glb are the bare package body.
