BAT54A-E3-08 from Vishay Intertech, 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); diode rated VRRM 30 V, IF 200 mA continuous. |
| 2 | K2 | passive | Cathode of the second Schottky diode (BAT54A common-anode configuration); diode rated VRRM 30 V, IF 200 mA continuous. |
| 3 | A | passive | Common anode of both Schottky diodes in the BAT54A (marking L42); each diode rated VRRM 30 V, IF 200 mA continuous. |
