TBAT54

TOSHIBA · Schottky Diodes · SOT-23-3

TBAT54 from TOSHIBA, 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 A passive Anode of the single Schottky diode (VR 30 V, IO 200 mA, IFM 300 mA max).
2 NC unconnected No internal connection (N.C.).
3 K passive Cathode of the single Schottky diode (VR 30 V, IO 200 mA, IFM 300 mA max).

CAD (KiCad official)

  • Symbol: TBAT54
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: tbat54-etched.step / tbat54-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tbat54.step / tbat54.glb are the bare package body.
