MMSZ8V2CW

YONGYUTAI · Zener Diodes · SOD-123

MMSZ8V2CW from YONGYUTAI, in a SOD-123. 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 K passive Cathode, the end marked with the color band; the Zener voltage is 8.2V nominal (7.7V min, 8.7V max) at 5mA.
2 A passive Anode, the end opposite the color band; forward voltage is 0.9V at IF=10mA.

CAD (KiCad official)

  • Symbol: MMSZ8V2CW
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mmsz8v2cw-etched.step / mmsz8v2cw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmsz8v2cw.step / mmsz8v2cw.glb are the bare package body.
