MM5Z12

CBI · Zener Diodes · SOD-523

MM5Z12 from CBI, in a SOD-523. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Cathode passive Cathode terminal of the Zener diode, marked as pin 1 in the SOD-523 pinning (datasheet gives no pin-specific electrical limits).
2 Anode passive Anode terminal of the Zener diode, marked as pin 2 in the SOD-523 pinning (datasheet gives no pin-specific electrical limits).

CAD (KiCad official)

  • Symbol: MM5Z12
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: mm5z12-etched.step / mm5z12-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm5z12.step / mm5z12.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: CBI datasheet (4 pp, sha256 08361ae46351a6f1, retrieved 2026-10-21, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
