BZT52C43

FOSAN · Zener Diodes · SOD-123

BZT52C43 from FOSAN, 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 K passive Cathode (marked − in the symbol on page 1); the zener voltage VZ for BZT52C43 is 40.0 V min to 46.0 V max at IZT=5mA, and total dissipation is 500 mW at Ta=25℃.
2 A passive Anode (marked + in the symbol on page 1); forward voltage VF is 0.9 V at IF=10mA, and junction and storage temperature is 150℃ and -65 to +150℃.

  • Symbol: BZT52C43
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52c43-etched.step / bzt52c43-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52c43.step / bzt52c43.glb are the bare package body.
