BAT54AWT

Yangzhou Yangjie Elec Tech · Schottky Barrier Diodes (SBD) · SOT-323(SC-70)

BAT54AWT from Yangzhou Yangjie Elec Tech, in a SOT-323(SC-70). 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 (BAT54AWT dual common-anode configuration), rated VR 30 V and IF 200 mA continuous.
2 K2 passive Cathode of the second Schottky diode (BAT54AWT dual common-anode configuration), rated VR 30 V and IF 200 mA continuous.
3 A passive Common anode of both Schottky diodes in BAT54AWT, with VF of 0.32 V max at IFM=1mA and 0.4 V max at IFM=10mA per diode.
