BVSS123LT1G 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 | Gate | input | Gate control terminal; VGS is limited to ±20 Vdc continuous and ±40 Vpk non-repetitive, with VGS(th) of 1.6 to 2.6 Vdc. |
| 2 | Source | passive | Source terminal and reference for the gate and drain ratings; the datasheet gives no separate source-pin limit. |
| 3 | Drain | passive | Drain terminal; VDSS is 100 Vdc, with continuous drain current ID of 0.17 Adc and pulsed IDM of 0.68 Adc, and the package power dissipation may lower the continuous current. |
