BAS20DW-7 from Diodes Incorporated, in a SOT-363. 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 diode 1, connected internally to the bottom-left pin of the top-view schematic; each diode is rated 200 V VRRM (BAS20DW). |
| 2 | NC | unconnected | Bottom-middle pin, shown with no internal connection in the schematic. |
| 3 | A2 | passive | Anode of diode 2, connected internally to the bottom-right pin of the top-view schematic; each diode is rated 200 V VRRM (BAS20DW). |
| 4 | C2 | passive | Cathode of diode 2, connected internally to the top-right pin of the top-view schematic. |
| 5 | NC | unconnected | Top-middle pin, shown with no internal connection in the schematic. |
| 6 | C1 | passive | Cathode of diode 1, connected internally to the top-left pin of the top-view schematic. |
