BAV99RWT1G from onsemi, in a SOT-323. 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 | CATHODE | passive | Cathode of the first diode of the dual series pair; each diode is rated for 100 Vdc reverse voltage and 215 mAdc forward current. |
| 2 | ANODE | passive | Anode of the second diode of the dual series pair; each diode is rated for 100 Vdc reverse voltage and 215 mAdc forward current. |
| 3 | ANODE-CATHODE | passive | Common node joining the anode of one diode to the cathode of the other in the Style 10 dual series configuration; each diode is rated for 100 Vdc reverse voltage and 215 mAdc forward current. |
