BZB84-C6V2

Nexperia · Zener Diodes · SOT-23

BZB84-C6V2 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, which shares a common anode with diode 2 on pin 3; the datasheet gives no separate pin-level voltage or current limit, only the device ratings (Ptot 300 mW at Tamb ≤ 25 °C) and that pins 1 and 2 are the soldering points for Rth(j-sp).
2 cathode (diode 2) passive Cathode of Zener diode 2, which shares a common anode with diode 1 on pin 3 (dual common anode configuration); the datasheet gives no separate pin-level limit, and pin 2 is one of the two soldering points for Rth(j-sp).
3 common anode passive Common anode shared by both Zener diodes, giving the dual common anode configuration of the BZB84 series; the datasheet gives no separate pin-level limit for this pin.

CAD (KiCad official)

  • Symbol: BZB84-C6V2
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bzb84-c6v2-etched.step / bzb84-c6v2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzb84-c6v2.step / bzb84-c6v2.glb are the bare package body.
