BZX84C3V0

Changjing · Zener Diodes · SOT-23

BZX84C3V0 from Changjing, 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 schematic shows it connected to pin 3 through the diode, with VF 0.9 V at IF = 10 mA.
2 NC unconnected Not connected internally; the schematic shows pin 2 as an unconnected terminal.
3 K passive Cathode of the zener diode; for the BZX84C3V0 the zener voltage is 3.0 V nominal (2.8 V to 3.2 V) at IZT = 5 mA, with 300 mW maximum power dissipation.

CAD (KiCad official)

  • Symbol: BZX84C3V0
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bzx84c3v0-etched.step / bzx84c3v0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c3v0.step / bzx84c3v0.glb are the bare package body.
