BAT54TA

Diodes Incorporated · Schottky Barrier Diodes (SBD) · SOT-23

BAT54TA from Diodes Incorporated, 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 A passive Anode of the single Schottky diode (bottom-left terminal in the top-view diagram); VRRM 30 V, IO 200 mA.
2 NC unconnected Bottom-right terminal, shown with no internal connection in the BAT54TA diagram.
3 K passive Cathode of the single Schottky diode (top terminal in the top-view diagram); VRRM 30 V, IO 200 mA.

CAD (KiCad official)

  • Symbol: BAT54TA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bat54ta-etched.step / bat54ta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54ta.step / bat54ta.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (5 pp, sha256 28cfafe91b59a7f2, retrieved 2026-11-10, tier: manufacturer)
  • 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).
