MM5Z12V

YONGYUTAI · Zener Diodes · SOD-523

MM5Z12V from YONGYUTAI, 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 MM5Z12V silicon planar Zener diode, which has a standard Zener breakdown voltage of 12 V.
2 Anode passive Anode terminal of the MM5Z12V Zener diode; the datasheet gives a maximum forward voltage VF of 0.9 V at IF = 10 mA.

CAD (KiCad official)

  • Symbol: MM5Z12V
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: mm5z12v-etched.step / mm5z12v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm5z12v.step / mm5z12v.glb are the bare package body.
