BAV70T from Changjing, 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 | A1 | passive | Anode of diode 1 in the BAV70T dual common-cathode switching diode (VR 85 V, IF 75 mA per the maximum ratings). |
| 2 | A2 | passive | Anode of diode 2 in the BAV70T dual common-cathode switching diode (VR 85 V, IF 75 mA per the maximum ratings). |
| 3 | K | passive | Common cathode of both diodes in the BAV70T (marking JJ), joined internally to both diode cathodes. |
