BZX84C43

FOSAN · Zener Diodes · SOT-23

BZX84C43 from FOSAN, 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, per the internal configuration drawing (pin 1 connects through the diode to pin 3).
2 NC unconnected No internal connection; pin 2 is shown as an unconnected terminal in the internal configuration drawing.
3 K passive Cathode of the zener diode, per the internal configuration drawing (VZ 40.0-46.0 V at IZ=2 mA for BZX84C43).

CAD (KiCad official)

  • Symbol: BZX84C43
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bzx84c43-etched.step / bzx84c43-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c43.step / bzx84c43.glb are the bare package body.

Provenance
