BAT54C-G 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 | A1 | passive | Anode of the first Schottky diode (BAT54C common-cathode configuration), 30 V max reverse voltage and 200 mA max forward continuous current. |
| 2 | A2 | passive | Anode of the second Schottky diode (BAT54C common-cathode configuration), 30 V max reverse voltage and 200 mA max forward continuous current. |
| 3 | K | passive | Common cathode of both Schottky diodes in the BAT54C (marking KL3), 30 V max DC blocking voltage. |
