MM3Z3V0-BL

ST Semtech · Zener Diodes · SOD-323

MM3Z3V0-BL from ST Semtech, in a SOD-323. 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 of the Zener diode per the PINNING table; the datasheet gives no pin-specific limits, only the device ratings of 300 mW total power dissipation and 150 °C junction temperature.
2 Anode passive Anode of the Zener diode per the PINNING table and the '2 Anode' label on the top view; the datasheet gives no pin-specific limits, only the device ratings of 300 mW total power dissipation and 150 °C junction temperature.

CAD (KiCad official)

  • Symbol: MM3Z3V0-BL
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: mm3z3v0-bl-etched.step / mm3z3v0-bl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm3z3v0-bl.step / mm3z3v0-bl.glb are the bare package body.
