BAS521WT

CBI · Switching Diodes · SOD-523

BAS521WT from CBI, in a SOD-523. 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 BAS521WT high voltage switching diode; the device is rated for a 300 V reverse voltage (VR) and 225 mA continuous forward current.
2 Anode passive Anode terminal of the BAS521WT high voltage switching diode, the counterpart to the cathode on pin 1 in the SOD-523 package.

CAD (KiCad official)

  • Symbol: BAS521WT
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: bas521wt-etched.step / bas521wt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas521wt.step / bas521wt.glb are the bare package body.

Provenance
