BAT54CFILM from STMicroelectronics, 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 (40 V VRRM, 300 mA continuous forward current), bottom-left pin in the top-view drawing. |
| 2 | A2 | passive | Anode of the second Schottky diode (40 V VRRM, 300 mA continuous forward current), bottom-right pin in the top-view drawing. |
| 3 | K | passive | Common cathode of both Schottky diodes (BAT54CFILM common cathode configuration), top pin in the top-view drawing. |
