BAV99LT3G from onsemi, 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 | ANODE | passive | Anode of the first diode in the dual series pair; each diode is rated for 100 V reverse voltage and 215 mA forward current (Maximum Ratings, page 1). |
| 2 | CATHODE | passive | Cathode of the second diode in the dual series pair; each diode is rated for 100 V reverse voltage and 215 mA forward current (Maximum Ratings, page 1). |
| 3 | CATHODE-ANODE | passive | Common junction connecting the cathode of one diode to the anode of the other in the series pair; per-diode limits are 100 V reverse and 215 mA forward (Maximum Ratings, page 1). |
