BAW56-RTK

KEC Semicon · Switching Diodes · SOT-23

BAW56-RTK from KEC Semicon, 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 CATHODE 1 passive Cathode of diode 1 in the SOT-23 dual-diode package; the datasheet gives no pin-specific electrical limits.
2 CATHODE 2 passive Cathode of diode 2 in the SOT-23 dual-diode package; the datasheet gives no pin-specific electrical limits.
3 ANODE passive Common anode shared by both diodes in the SOT-23 package; the datasheet gives no pin-specific electrical limits.

CAD (KiCad official)

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