BAW56 A1

DOWO · Switching Diodes · SOT-23

BAW56 A1 from DOWO, in a SOT-23. 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 K1 passive Cathode of the first switching diode in the BAW56 (marking A1) dual common-anode pair, rated VR 70 V and IF 200 mA.
2 K2 passive Cathode of the second switching diode in the BAW56 (marking A1) dual common-anode pair, rated VR 70 V and IF 200 mA.
3 A (common) passive Common anode node of both BAW56 diodes, shown as the shared pin 3 in the package schematic.

CAD (KiCad official)

  • Symbol: BAW56 A1
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: baw56-a1-etched.step / baw56-a1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); baw56-a1.step / baw56-a1.glb are the bare package body.
