LBAT54SWT1G from LRC, 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 | ANODE | passive | Anode terminal of the first diode in the dual series Schottky configuration, with the device rated for 30 V reverse voltage and 200 mA DC forward current. |
| 2 | CATHODE | passive | Cathode terminal of the second diode in the dual series Schottky configuration, with the device rated for 30 V reverse voltage and 200 mA DC forward current. |
| 3 | CATHODE/ANODE | passive | Common internal junction between the two series Schottky diodes, connecting the cathode of one diode to the anode of the other. |
