BSS123X from Shenzhen JingYang, 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 | G | input | Gate; gate-source voltage limited to ±20 V, with threshold VGS(th) 1.5 to 2.5 V at ID=250 µA and RDS(on) specified at VGS=10 V and 4.5 V. |
| 2 | S | passive | Source terminal of the N-channel MOSFET; continuous drain current is 0.17 A at TC=25℃. |
| 3 | D | passive | Drain; drain-source voltage rated 100 V, continuous current 0.17 A and pulsed current 0.68 A. |
