MMSZ4711T1G

onsemi · Zener Diodes · SOD-123

MMSZ4711T1G 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, identified on the package by the polarity band (SOD-123 Style 1: pin 1 = Cathode).
2 Anode passive Anode terminal of the Zener diode, opposite the cathode (polarity band) side (SOD-123 Style 1: pin 2 = Anode).

CAD (KiCad official)

  • Symbol: MMSZ4711T1G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mmsz4711t1g-etched.step / mmsz4711t1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmsz4711t1g.step / mmsz4711t1g.glb are the bare package body.
