BAS40-05T

Changjing · Schottky Barrier Diodes (SBD) · SOT-523

BAS40-05T from Changjing, in a SOT-523. 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 first Schottky diode (40 V VRRM, 200 mA continuous forward current), pin 1 of the SOT-523 package.
2 A2 passive Anode of second Schottky diode (40 V VRRM, 200 mA continuous forward current), pin 2 of the SOT-523 package.
3 K passive Common cathode of both Schottky diodes (BAS40-05T, marking 45), pin 3 of the SOT-523 package.

CAD (KiCad official)

  • Symbol: BAS40-05T
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: bas40-05t-etched.step / bas40-05t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas40-05t.step / bas40-05t.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Changjing datasheet (4 pp, sha256 f5a8c7e012bc6ff5, retrieved 2026-11-04, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
