BAT54WT

amsem · Schottky Diodes · SOT-323

BAT54WT from amsem, in a SOT-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 A passive Anode of the single Schottky diode (Figure 1, bottom-left lead); 30 V maximum DC blocking voltage, 200 mA forward continuous current.
2 NC unconnected No internal connection on the single BAT54WT (Figure 1 shows the bottom-right lead unconnected).
3 K passive Cathode of the single Schottky diode (Figure 1, top lead); 30 V maximum DC blocking voltage, 200 mA forward continuous current.

CAD (KiCad official)

  • Symbol: BAT54WT
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: bat54wt-etched.step / bat54wt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54wt.step / bat54wt.glb are the bare package body.
