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. |
