BAT54S-HE3-18 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 | A1 | passive | Anode of the first Schottky diode in the dual serial (BAT54S) configuration, with a repetitive peak reverse voltage of 30 V and 200 mA forward continuous current. |
| 2 | K2 | passive | Cathode of the second Schottky diode in the dual serial (BAT54S) configuration, with a repetitive peak reverse voltage of 30 V and 200 mA forward continuous current. |
| 3 | K1/A2 | passive | Common midpoint joining the cathode of the first diode and the anode of the second diode in the series (BAT54S) configuration. |
