BAV99Q-7-F from Diodes Incorporated, 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 (left diode in the top-view internal schematic); series-connected to pin 3, with VRRM 75 V and IFM 300 mA continuous forward current. |
| 2 | K2 | passive | Cathode of the second diode (right diode in the top-view internal schematic); series-connected to pin 3, with VRRM 75 V and IFM 300 mA continuous forward current. |
| 3 | K1/A2 | passive | Common node joining the cathode of the first diode and the anode of the second diode (single top terminal in the internal schematic). |
