MMBZ5242B

DOWO · Zener Diodes · SOT-23

MMBZ5242B from DOWO, 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 12V zener diode (Vz 11.40-12.60V at IZT=20mA), shown as pin 1 in the SOT-23 symbol.
2 NC unconnected No internal connection; pin 2 is drawn as an unconnected pin in the SOT-23 symbol.
3 K passive Cathode of the 12V zener diode (500mW power dissipation, 0.9V forward voltage at IF=10mA), shown as pin 3 in the SOT-23 symbol.

CAD (KiCad official)

  • Symbol: MMBZ5242B
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbz5242b-etched.step / mmbz5242b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbz5242b.step / mmbz5242b.glb are the bare package body.
