Public Made by Adom

by adom

SMC(Sangdest Microelectronicstronic (Nanjing)) Schottky Barrier Diodes (SBD), SMC(DO-214AB). 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: SK520
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: sk520-etched.step / sk520-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sk520.step / sk520.glb are the bare package body.
