BAR43SFILM

STMicroelectronics · Schottky Diodes · SOT-23-3L

BAR43SFILM from STMicroelectronics, in a SOT-23-3L. 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/K2 passive Internal series mid-point tying the anode of one BAR43 Schottky die (A1) to the cathode of the second die (K2); this is the top-left lead of the SOT23-3L outline for the BAR43SFILM 'series' variant, per Figure on page 1.
2 A2 passive Anode of the second (outer) BAR43 Schottky diode in the series pair; bottom-left lead of the SOT23-3L outline for BAR43SFILM, per Figure on page 1.
3 K1 passive Cathode of the first (outer) BAR43 Schottky diode in the series pair; single right-side lead of the SOT23-3L outline for BAR43SFILM, per Figure on page 1.

CAD (KiCad official)

  • Symbol: BAR43SFILM
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: bar43sfilm-etched.step / bar43sfilm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bar43sfilm.step / bar43sfilm.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (7 pp, sha256 e965d2b77f22fd7d, retrieved 2026-09-29, 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).
