AD-BAT54A

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

AD-BAT54A from Changjing, 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 (AD-BAT54A common-anode pair), with 30 V maximum DC blocking voltage VR.
2 K2 passive Cathode of the second Schottky diode (AD-BAT54A common-anode pair), with 30 V maximum DC blocking voltage VR.
3 A passive Common anode of both Schottky diodes, with 200 mA maximum forward continuous current per the datasheet rating.
