BZB84-B2V4

Nexperia · Zener Diodes · SOT-23

BZB84-B2V4 from Nexperia, 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 cathode (diode 1) passive Cathode of Zener diode 1 in the dual common-anode BZB84 device; the datasheet gives no separate limit for this pin.
2 cathode (diode 2) passive Cathode of Zener diode 2 in the dual common-anode BZB84 device; the datasheet gives no separate limit for this pin.
3 common anode passive Common anode shared by both Zener diodes, giving the dual common-anode configuration.

CAD (KiCad official)

  • Symbol: BZB84-B2V4
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bzb84-b2v4-etched.step / bzb84-b2v4-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzb84-b2v4.step / bzb84-b2v4.glb are the bare package body.
