BAT54S-E3-18 from Vishay Intertech, in a SOT-23-3. 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 of the dual series (BAT54S) pair, rated VRRM 30 V and IF 200 mA continuous. |
| 2 | K2 | passive | Cathode of the second Schottky diode of the BAT54S series pair, rated VRRM 30 V and IF 200 mA continuous. |
| 3 | K1/A2 | passive | Common midpoint connecting the cathode of the first diode to the anode of the second diode in the BAT54S dual serial configuration. |
