LBAS40-04LT1G

LRC · Schottky Diodes · SOT-23

LBAS40-04LT1G from LRC, 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 Anode passive Anode terminal of the BAS40-04 double (series) Schottky diode; the device has a maximum continuous forward current of 120 mA and a continuous reverse voltage of 40 V.
2 Cathode passive Cathode terminal of the BAS40-04 double (series) Schottky diode; the device has a maximum continuous forward current of 120 mA and a continuous reverse voltage of 40 V.
3 Cathode/Anode passive Internal junction pin of the BAS40-04 double diode, connecting the cathode of one diode to the anode of the other, per the datasheet pin label.

CAD (KiCad official)

  • Symbol: LBAS40-04LT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: lbas40-04lt1g-etched.step / lbas40-04lt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lbas40-04lt1g.step / lbas40-04lt1g.glb are the bare package body.

Provenance

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

  • Datasheet: LRC datasheet (4 pp, sha256 011c395a9fad0dcd, retrieved 2026-10-20, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
