BAT54SWT-TP from MCC(Micro Commercial Components), in a SOT-323-3. 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, on the bottom-left pin of the Figure 4 series configuration (30V VR, 200mA IF). |
| 2 | K2 | passive | Cathode of the second Schottky diode, on the bottom-right pin of the Figure 4 series configuration (30V VR, 200mA IF). |
| 3 | K1/A2 | passive | Common node joining the cathode of the first diode to the anode of the second diode, on the top pin of the Figure 4 series configuration. |
