BAS70T from CBI, in a SOT-523. 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 (BAS70T, marking 7C); VRRM/VR 70 V, IFM 70 mA. |
| 2 | NC | unconnected | Not connected internally in the single-diode BAS70T; the symbol shows no diode on this lead. |
| 3 | K | passive | Cathode of the single Schottky diode (BAS70T, marking 7C); VRRM/VR 70 V, IFM 70 mA. |
