BZX84C3V9LT1G

onsemi · Zener Diodes · SOT-23

BZX84C3V9LT1G from onsemi, 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 Anode passive Anode of the Zener diode (Style 8 pin 1); the Zener breakdown voltage is specified from anode to cathode.
2 NC unconnected No connection (Style 8 pin 2); the datasheet assigns no electrical function to this pin.
3 Cathode passive Cathode of the Zener diode (Style 8 pin 3), identified on the package by the polarity band.

CAD (KiCad official)

  • Symbol: BZX84C3V9LT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bzx84c3v9lt1g-etched.step / bzx84c3v9lt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84c3v9lt1g.step / bzx84c3v9lt1g.glb are the bare package body.
