BAT54-AU_R1_000A1 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 | A | passive | Anode of the single Schottky diode (30 V VRRM, 0.2 A average forward current). |
| 2 | NC | unconnected | No internal connection in the single BAT54-AU diode; the pin is unused in the package drawing. |
| 3 | K | passive | Cathode of the single Schottky diode (30 V maximum DC blocking voltage). |
