SBAV199LT1G from onsemi, in a SOT-23-3. 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 | ANODE | passive | Anode of the first diode in the dual series pair; the datasheet gives a device reverse voltage of 70 Vdc and a forward current of 215 mAdc, with ratings stated for each diode. |
| 2 | CATHODE | passive | Cathode of the second diode in the dual series pair; the datasheet gives a device reverse voltage of 70 Vdc and a forward current of 215 mAdc, with ratings stated for each diode. |
| 3 | CATHODE/ANODE | passive | Shared common connection that joins the cathode of one diode to the anode of the other in the series configuration; the datasheet gives no separate limit for this pin. |
