BZX84C2V4Q

Yangzhou Yangjie Elec Tech · Zener Diodes · SOT-23

BZX84C2V4Q from Yangzhou Yangjie Elec Tech, 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 Zener diode anode, shown on the page 1 internal diagram connected to the anode side of the diode symbol.
2 NC unconnected Pin 2 is shown on the page 1 diagram with no internal connection to the diode.
3 K passive Zener diode cathode, shown on the page 1 internal diagram connected to the cathode (bar) side of the diode symbol; BZX84C2V4Q has Vz 2.4V typ (2.28 to 2.56V) at 5mA.

CAD (KiCad official)

  • Symbol: BZX84C2V4Q
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bzx84c2v4q-etched.step / bzx84c2v4q-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c2v4q.step / bzx84c2v4q.glb are the bare package body.
