MMBZ9V1AL

FUXINSEMI · Zener Diodes · SOT-23

MMBZ9V1AL from FUXINSEMI, in a SOT-23. 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 K1 passive Cathode of the first Zener diode (unidirectional channel 1, 9.1 V nominal breakdown, 6.0 V working peak reverse voltage); tie to pin 2 for a single bidirectional configuration.
2 K2 passive Cathode of the second Zener diode (unidirectional channel 2, 9.1 V nominal breakdown, 6.0 V working peak reverse voltage); tie to pin 1 for a single bidirectional configuration.
3 A passive Common anode of both Zener diodes, shared by the two unidirectional channels.

  • Symbol: MMBZ9V1AL
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbz9v1al-etched.step / mmbz9v1al-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbz9v1al.step / mmbz9v1al.glb are the bare package body.
