CZRF5V1B-HF

Public Made by Adom

by adom

Comchip Zener Diodes, SOD-323F. 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: CZRF5V1B-HF
  • Footprint: Diode_SMD:D_SOD-323F
  • 3D model: SOD-323F (KiCad packages3D, STEP)
  • 3D model files: czrf5v1b-hf-etched.step / czrf5v1b-hf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); czrf5v1b-hf.step / czrf5v1b-hf.glb are the bare package body.
