BAV21WT

Shikues · Switching Diodes · SOD-523

BAV21WT from Shikues, 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 BAV19WT/BAV20WT/BAV21WT diode, with reverse voltage rated up to 200 V (VR) and repetitive peak reverse voltage up to 250 V (VRRM) for the BAV21WT.
2 Anode passive Anode terminal of the diode, with average rectified forward current limited to 200 mA (IF(AV)) and forward continuous current of 400 mA (IFM).

CAD (KiCad official)

  • Symbol: BAV21WT
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: bav21wt-etched.step / bav21wt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bav21wt.step / bav21wt.glb are the bare package body.
