SK420

Public Made by Adom

by adom

(DIOTEC) Schottky Barrier Diodes (SBD), DO-214AB(SMC). 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: SK420
  • Footprint: Diode_SMD:D_SMC
  • 3D model: DO-214AB(SMC) (KiCad packages3D, STEP)
  • 3D model files: sk420-etched.step / sk420-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sk420.step / sk420.glb are the bare package body.
