BAT54CTA

Diodes Incorporated · Schottky Diodes · SOT-23-3

BAT54CTA from Diodes Incorporated, in a SOT-23-3. 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 (bottom-left pin in top view); the diode conducts to the common cathode on pin 3, with VRRM 30 V and IO 200 mA per the ratings.
2 A2 passive Anode of the second Schottky diode (bottom-right pin in top view); the diode conducts to the common cathode on pin 3, with VRRM 30 V and IO 200 mA per the ratings.
3 K passive Common cathode of both Schottky diodes (top pin in top view), reverse voltage limit VR 30 V.

CAD (KiCad official)

  • Symbol: BAT54CTA
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: bat54cta-etched.step / bat54cta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54cta.step / bat54cta.glb are the bare package body.
