BAT54AFILM from STMicroelectronics, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K1 | passive | Cathode of diode 1 of the common-anode pair; blocks up to VRRM = 40 V reverse and conducts up to IF = 300 mA continuous forward current (IFSM = 1.25 A, 10 ms surge). |
| 2 | K2 | passive | Cathode of diode 2 of the common-anode pair; blocks up to VRRM = 40 V reverse and conducts up to IF = 300 mA continuous forward current (IFSM = 1.25 A, 10 ms surge). |
| 3 | A | passive | Common anode terminal shared by both Schottky diodes, carrying the combined forward current with VF up to 900 mV typical at IF = 100 mA. |
