BAT54WFILM from STMicroelectronics, in a SOT-323. 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 (40 V VRRM, 300 mA continuous forward current), drawn at the bottom-left pad in the top view. |
| 2 | NC | unconnected | Bottom-right pad in the top-view drawing; it has no connection to the single diode symbol. |
| 3 | K | passive | Cathode of the single Schottky diode (40 V VRRM, 300 mA continuous forward current), drawn at the top pad in the top view. |
