MMSZ10VCW

YONGYUTAI · Zener Diodes · SOD-123

MMSZ10VCW 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 color-band end; the Zener voltage is 10 V nominal (9.4 V min to 10.6 V max) at Izt = 5 mA, with maximum reverse current 0.2 uA at VR = 7.0 V.
2 A passive Anode, the end opposite the color band; forward voltage is 0.9 V at IF = 10 mA and power dissipation is 500 mW maximum.

CAD (KiCad official)

  • Symbol: MMSZ10VCW
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mmsz10vcw-etched.step / mmsz10vcw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmsz10vcw.step / mmsz10vcw.glb are the bare package body.
