MM5Z9V1T1G

onsemi · Zener Diodes · SOD-523

MM5Z9V1T1G from onsemi, in a SOD-523. 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, marked by the polarity band on the SOD-523 package (Style 1: PIN 1 CATHODE).
2 Anode passive Anode of the Zener diode, the terminal opposite the cathode (Style 1: PIN 2 ANODE).

CAD (KiCad official)

  • Symbol: MM5Z9V1T1G
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: mm5z9v1t1g-etched.step / mm5z9v1t1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm5z9v1t1g.step / mm5z9v1t1g.glb are the bare package body.
