BAR43S

Changjing · Schottky Diodes · SOT-23

BAR43S from Changjing, 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 A1 passive Anode of the first Schottky diode, whose cathode connects to pin 3 (series pair, BAR43S marking DA5); 30 V peak repetitive reverse voltage, 200 mA average forward current.
2 K2 passive Cathode of the second Schottky diode, whose anode connects to pin 3 (series pair); 30 V peak repetitive reverse voltage, 200 mA average forward current.
3 A2/K1 passive Common midpoint node joining the cathode of the first diode (pin 1) and the anode of the second diode (pin 2) in the series configuration.

CAD (KiCad official)

  • Symbol: BAR43S
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bar43s-etched.step / bar43s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bar43s.step / bar43s.glb are the bare package body.
