MM1Z27V

YONGYUTAI · Zener Diodes · SOD-123

MM1Z27V 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 by the color band; the Zener (reverse breakdown) voltage of the MM1Z27V is 25.1 V min to 28.9 V max at Izt = 2 mA.
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.

CAD (KiCad official)

  • Symbol: MM1Z27V
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mm1z27v-etched.step / mm1z27v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm1z27v.step / mm1z27v.glb are the bare package body.
