BAT54SW from hongjiacheng, in a SOT-323. 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 BAT54SW series pair (30V VR, 200mA IF(AV) rating); pin 1 of the SOT-323 function diagram. |
| 2 | K2 | passive | Cathode of the second Schottky diode in the BAT54SW series pair (30V VR, 200mA IF(AV) rating); pin 2 of the SOT-323 function diagram. |
| 3 | K1/A2 | passive | Common midpoint joining the cathode of the first diode and the anode of the second diode in the BAT54SW series configuration; pin 3 of the SOT-323 function diagram. |
