BAS40WT-05 from Yangzhou Yangjie Elec Tech, in a SOT-323(SC-70). 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 (the datasheet pin diagram shows pins 1 and 2 as the two outer terminals of the dual diode); VRRM/VR 40 V, IFM 200 mA. |
| 2 | A2 | passive | Anode of the second Schottky diode (outer terminal of the dual diode); VRRM/VR 40 V, IFM 200 mA. |
| 3 | K (common) | passive | Common cathode node joining both diodes in the BAS40WT-05 (marking code 45); VR 40 V. |
