BZB84-C56

Nexperia · Zener Diodes · SOT-23

BZB84-C56 from Nexperia, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K1 passive Cathode of Zener diode 1. Reverse breakdown to the common anode (pin 3) at Vz ≈ 54.9-57.1 V (Iz = 2 mA). Forward voltage ≤0.9 V at IF = 10 mA; max forward current 200 mA.
2 K2 passive Cathode of Zener diode 2. Reverse breakdown to the common anode (pin 3) at Vz ≈ 54.9-57.1 V (Iz = 2 mA). Forward voltage ≤0.9 V at IF = 10 mA; max forward current 200 mA.
3 A passive Common anode shared by both Zener diodes (dual common-anode topology). Serves as the return node for the two independent Zener/forward diode paths on pins 1 and 2.

CAD (KiCad official)

  • Symbol: BZB84-C56
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bzb84-c56-etched.step / bzb84-c56-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzb84-c56.step / bzb84-c56.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Nexperia datasheet (14 pp, sha256 d909f500a84da6be, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
