MM1Z24B

ST Semtech · Zener Diodes · SOD-123

MM1Z24B 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 Zener diode, identified by the cathode line marking on the SOD-123 package. The datasheet gives no pin-level electrical limits; the 500 mW total power dissipation and 150 °C junction temperature are device ratings.
2 Anode passive Anode terminal of the Zener diode on the SOD-123 two-lead package. The datasheet gives no pin-level electrical limits for this terminal.

CAD (KiCad official)

  • Symbol: MM1Z24B
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mm1z24b-etched.step / mm1z24b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm1z24b.step / mm1z24b.glb are the bare package body.
