BSD3A031V

BORN · ESD And Surge Protection (TVS/ESD) · SOD-323

BSD3A031V from BORN, in a SOD-323. 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 of the unidirectional ESD protection diode, connected to the protected line (e.g. USB Vbus/power line) with a 3.3V reverse stand-off voltage.
2 Anode passive Anode of the unidirectional ESD protection diode, normally connected to ground.

CAD (KiCad official)

  • Symbol: BSD3A031V
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: bsd3a031v-etched.step / bsd3a031v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bsd3a031v.step / bsd3a031v.glb are the bare package body.
