BZX84C22

MDD（Microdiode Electronics） · Zener Diodes · SOT-23

BZX84C22 from MDD（Microdiode Electronics）, 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 page 1 symbol shows the diode arrow pointing from pin 1 toward pin 3.
2 NC unconnected No connection; the page 1 symbol draws pin 2 as an open terminal with no link to the diode.
3 K passive Cathode of the Zener diode; for BZX84C22, VZ is 22 V nominal (20.8 to 23.3 V) at IZT = 5 mA.

CAD (KiCad official)

  • Symbol: BZX84C22
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bzx84c22-etched.step / bzx84c22-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c22.step / bzx84c22.glb are the bare package body.
