BAT54S RFG from Taiwan Semiconductor(Taiwan Semicon), 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 (bottom-left pin in the BAT54S pin configuration drawing); 30V minimum reverse breakdown, 200mA forward continuous current. |
| 2 | K2 | passive | Cathode of the second Schottky diode (bottom-right pin in the BAT54S pin configuration drawing); 30V minimum reverse breakdown, 200mA forward continuous current. |
| 3 | K1/A2 | passive | Common center node joining the cathode of the first diode to the anode of the second diode in the series BAT54S configuration (top pin in the drawing). |
