EDZVT2R18B

Public Made by Adom

by adom

ROHM Semicon Zener Diodes, 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: EDZVT2R18B
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: edzvt2r18b-etched.step / edzvt2r18b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); edzvt2r18b.step / edzvt2r18b.glb are the bare package body.
