BAS70W from CBI, in a SOT-323. 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 | A | passive | Anode of the single Schottky diode (BAS70W, marking K73), rated for VR 70 V and IF 70 mA continuous. |
| 2 | NC | unconnected | No internal connection on the single-diode BAS70W; the symbol shows this lead unconnected. |
| 3 | K | passive | Cathode of the single Schottky diode (BAS70W, marking K73), rated for VR 70 V and IF 70 mA continuous. |
