BZT52C20

hongjiacheng · Zener Diodes · SOD-123

BZT52C20 from hongjiacheng, 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, the end marked by the cathode line on the package; the zener voltage VZ of 19.0 to 21.0 V (20 V nominal) at IZT=5 mA appears in reverse bias on this pin relative to the anode.
2 A passive Anode, the end opposite the cathode line; forward voltage VF is 0.9 V at IF=10 mA and power dissipation is limited to 350 mW.

CAD (KiCad official)

  • Symbol: BZT52C20
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52c20-etched.step / bzt52c20-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52c20.step / bzt52c20.glb are the bare package body.
