Infineon Technologies · Schottky Barrier Diodes (SBD) · SOT-23

BAS40E6433 from Infineon Technologies, 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 A passive Anode of the single Schottky diode (VR max 40 V, IF max 120 mA).
2 NC unconnected Pin 2 is shown in the BAS40 pin diagram with no connection to the single diode.
3 K passive Cathode of the single Schottky diode (VR max 40 V, IF max 120 mA).

CAD (KiCad official)

  • Symbol: BAS40E6433
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0 mm tall, datasheet A, nominal). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: bas40e6433-etched.step / bas40e6433-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas40e6433.step / bas40e6433.glb are the bare package body.
