MM5Z4V3

CBI · Zener Diodes · SOD-523

MM5Z4V3 from CBI, 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; the datasheet rates total device dissipation at 200 mW and junction/storage temperature at -65 to +150 °C.
2 Anode passive Anode of the Zener diode; forward voltage is specified at 0.9 V maximum at IF = 10 mA.

CAD (KiCad official)

  • Symbol: MM5Z4V3
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: mm5z4v3-etched.step / mm5z4v3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm5z4v3.step / mm5z4v3.glb are the bare package body.
