BAT54A_R1_00301 from PANJIT International, 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 (BAT54A common-anode configuration, Fig.15 top view); 30 V peak repetitive reverse voltage, 0.2 A average forward current. |
| 2 | K2 | passive | Cathode of the second Schottky diode (BAT54A common-anode configuration, Fig.15 top view); 30 V peak repetitive reverse voltage, 0.2 A average forward current. |
| 3 | A | passive | Common anode of both Schottky diodes (BAT54A, Fig.15 top view); 30 V peak repetitive reverse voltage, 0.2 A average forward current per the datasheet. |
