BAS70KFILM

Public Made by Adom

by adom

STMicroelectronics Schottky Barrier Diodes (SBD), SOD-523. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

CAD (KiCad official)

  • Symbol: BAS70KFILM
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: bas70kfilm-etched.step / bas70kfilm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas70kfilm.step / bas70kfilm.glb are the bare package body.
