MM1Z2V0

ST Semtech · Zener Diodes · SOD-123

MM1Z2V0 from ST Semtech, 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 Cathode passive Cathode terminal of the silicon planar Zener diode, listed as pin 1 in the SOD-123 PINNING table; the datasheet gives total power dissipation of max. 500 mW for the device.
2 Anode passive Anode terminal of the silicon planar Zener diode, shown as pin 2 in the SOD-123 top view and symbol; the datasheet gives total power dissipation of max. 500 mW for the device.

CAD (KiCad official)

  • Symbol: MM1Z2V0
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mm1z2v0-etched.step / mm1z2v0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm1z2v0.step / mm1z2v0.glb are the bare package body.
