BZT52B27

BORN · Zener Diodes · SOD-123

BZT52B27 from BORN, 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 by the color band; the 27 V (26.46-27.54 V at IZT=2 mA) Zener voltage appears here, with max reverse current 0.1 uA at VR=18.9 V.
2 A passive Anode of the Zener diode; device power dissipation is 500 mW max and junction temperature is 150 °C max.

CAD (KiCad official)

  • Symbol: BZT52B27
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52b27-etched.step / bzt52b27-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52b27.step / bzt52b27.glb are the bare package body.
