CAD (KiCad official)

  • Symbol: BAS21VD
  • Footprint: Package_SO:TSOP-6_1.65x3.05mm_P0.95mm
  • 3D model: TSOP6 (KiCad packages3D, STEP)
  • 3D model files: bas21vd-etched.step / bas21vd-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas21vd.step / bas21vd.glb are the bare package body.
