BAS40W-04-7-F from Diodes Incorporated, 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 (bottom-left terminal in the top view), in series with diode 2 through pin 3; VR 40 V, IFM 200 mA. |
| 2 | K2 | passive | Cathode of the second Schottky diode (bottom-right terminal in the top view); VR 40 V, IFM 200 mA. |
| 3 | K1/A2 | passive | Common node joining the cathode of diode 1 and the anode of diode 2 (single top terminal in the top view). |
