BZT52C9V1

hongjiacheng · Zener Diodes · SOD-123

BZT52C9V1 from hongjiacheng, in a SOD-123. 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 K passive Cathode. Marked by the cathode band on the package body. Reverse-biased with respect to the anode; conducts at the Zener voltage VZ (nom. 9.1 V) when reverse current reaches IZT=5 mA.
2 A passive Anode. Forward-conducting terminal; VF = 0.9 V @ IF = 10 mA. Return path for the Zener regulation current.

CAD (KiCad official)

  • Symbol: BZT52C9V1
  • Footprint: Diode_SMD:D_SOD-123
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52c9v1-etched.step / bzt52c9v1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52c9v1.step / bzt52c9v1.glb are the bare package body.

Provenance

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

  • Datasheet: hongjiacheng datasheet (4 pp, sha256 1e58426ecb363e87, 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).
