BZT52B33

Shikues · Zener Diodes · SOD-123

BZT52B33 from Shikues, in a SOD-123. 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 passive Cathode terminal of the zener diode, labeled pin 1 on the SOD-123 outline and symbol; the datasheet gives no separate electrical limit for this pin beyond the device ratings (Ptot 500 mW, Tj/Tstg -55 to +150 °C).
2 Anode passive Anode terminal of the zener diode, labeled pin 2 on the SOD-123 outline and symbol; the datasheet gives no separate electrical limit for this pin beyond the device ratings (Ptot 500 mW, Tj/Tstg -55 to +150 °C).

CAD (KiCad official)

  • Symbol: BZT52B33
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52b33-etched.step / bzt52b33-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52b33.step / bzt52b33.glb are the bare package body.
