BAT54ATA

Diodes Incorporated · Schottky Diodes · SOT-23

BAT54ATA 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	K1	passive	Cathode of the first Schottky diode (bottom-left terminal in the top view); the part is rated VRRM 30 V and IO 200 mA per diode.
2	K2	passive	Cathode of the second Schottky diode (bottom-right terminal in the top view); the part is rated VRRM 30 V and IO 200 mA per diode.
3	A	passive	Common anode of both Schottky diodes (top terminal in the top view), with a maximum forward voltage of 0.8 V at IF = 100 mA.

CAD (KiCad official)

Symbol: BAT54ATA
Footprint: Package_TO_SOT_SMD:SOT-23
3D model: SOT-23 (KiCad packages3D, STEP)
3D model files: bat54ata-etched.step / bat54ata-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54ata.step / bat54ata.glb are the bare package body.
