LBAT40-04LT1G from LRC, 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 | Anode | passive | Anode of the first Schottky diode in the dual common-series configuration (40 V max continuous reverse voltage, 350 mA peak forward current). |
| 2 | Cathode | passive | Cathode of the second Schottky diode (40 V max continuous reverse voltage, 350 mA peak forward current). |
| 3 | Cathode/Anode | passive | Common node joining the cathode of one diode and the anode of the other in the series configuration. |
