SZMMSZ13T1G

onsemi · Zener Diodes · SOD-123

SZMMSZ13T1G from onsemi, 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; the cathode is indicated by the polarity band on the package.
2 ANODE passive Anode terminal of the Zener diode, opposite the cathode polarity band.

CAD (KiCad official)

  • Symbol: SZMMSZ13T1G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: szmmsz13t1g-etched.step / szmmsz13t1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); szmmsz13t1g.step / szmmsz13t1g.glb are the bare package body.
