BAV99WTQ from Yangzhou Yangjie Elec Tech, in a SOT-323(SC-70). 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 (D1), whose cathode connects internally to pin 3; the datasheet gives VBR 100V and IFAV 150mA with a single diode loaded. |
| 2 | K2 | passive | Cathode of the second diode (D2), whose anode connects internally to pin 3; the datasheet gives VBR 100V and IFAV 150mA with a single diode loaded. |
| 3 | K1/A2 | passive | Common junction between the cathode of D1 and the anode of D2 in the series pair; the datasheet gives VBR 100V and IFAV 150mA with a single diode loaded. |
