BAV70 RFG
Taiwan Semiconductor · Switching Diodes · SOT-23
BAV70 RFG from Taiwan Semiconductor, in a SOT-23. 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 diode in the BAV70 dual common-cathode pair; the drawing shows it at the bottom-left lead, and the datasheet gives 70 V peak repetitive reverse voltage and 200 mA mean forward current per the ratings table. |
| 2 | A2 | passive | Anode of the second diode in the BAV70 dual common-cathode pair; the drawing shows it at the bottom-right lead, and the datasheet gives 70 V peak repetitive reverse voltage and 200 mA mean forward current per the ratings table. |
| 3 | K | passive | Common cathode of both BAV70 diodes; the drawing shows it at the single top lead, and the datasheet gives 70 V peak repetitive reverse voltage for the part. |
