MMBZ5226B

hongjiacheng · Zener Diodes · SOT-23

MMBZ5226B from hongjiacheng, 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 A passive Anode of the Zener diode; the function diagram shows the diode arrow starting at pin 1.
2 NC unconnected No connection; pin 2 is shown unconnected in the function diagram.
3 K passive Cathode of the Zener diode (3.3V nominal VZ at IZT=20mA for MMBZ5226B, 3.14V min to 3.47V max); power dissipation 300mW.

CAD (KiCad official)

  • Symbol: MMBZ5226B
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbz5226b-etched.step / mmbz5226b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbz5226b.step / mmbz5226b.glb are the bare package body.
