BSS84W from Yangzhou Yangjie Elec Tech, 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 | G | input | Gate; gate-source voltage is limited to ±20 V absolute maximum, with threshold VGS(th) of -0.9 V min, -1.4 V typ, -2.0 V max at ID=-250μA. |
| 2 | S | passive | Source; continuous body-diode current IS is -0.17 A max and drain-source voltage rating is -60 V. |
| 3 | D | passive | Drain; continuous drain current is -0.17 A at TA=25℃ (-0.14 A at 70℃), pulsed 0.68 A, with VDS rated -60 V. |
