BAV70T-MS from MSKSEMI, 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 the first diode in the BAV70T-MS common-cathode dual (marking JJ); rated 85 V reverse voltage and 75 mA forward current. |
| 2 | A2 | passive | Anode of the second diode in the BAV70T-MS common-cathode dual; rated 85 V reverse voltage and 75 mA forward current. |
| 3 | K | passive | Common cathode of both diodes, joined internally at pin 3 in the BAV70T-MS symbol. |
