MM5Z11

CBI · Zener Diodes · SOD-523

MM5Z11 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 terminal of the MM5Z11 Zener diode; the datasheet gives no pin-level electrical limits, and the device total dissipation is rated at 200 mW.
2 Anode passive Anode terminal of the MM5Z11 Zener diode; the datasheet gives no pin-level electrical limits, and the device total dissipation is rated at 200 mW.

CAD (KiCad official)

  • Symbol: MM5Z11
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: mm5z11-etched.step / mm5z11-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm5z11.step / mm5z11.glb are the bare package body.
