BAT54CFILM

STMicroelectronics · Schottky Diodes · SOT-23

BAT54CFILM from STMicroelectronics, 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 (40 V VRRM, 300 mA continuous forward current), bottom-left pin in the top-view drawing.
2 A2 passive Anode of the second Schottky diode (40 V VRRM, 300 mA continuous forward current), bottom-right pin in the top-view drawing.
3 K passive Common cathode of both Schottky diodes (BAT54CFILM common cathode configuration), top pin in the top-view drawing.

CAD (KiCad official)

  • Symbol: BAT54CFILM
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bat54cfilm-etched.step / bat54cfilm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54cfilm.step / bat54cfilm.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (15 pp, sha256 47b6e3175bbe78ae, retrieved 2026-10-03, 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).
