BSS84AK-VB from VBsemi Elec, in a SOT-23(TO-236). 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 of the P-channel MOSFET; gate-source voltage is rated ±20 V with a threshold of -1 to -3 V (VDS = VGS, ID = -250 µA). |
| 2 | S | passive | Source of the P-channel MOSFET, used for high-side switching; drain-source voltage is rated -60 V. |
| 3 | D | passive | Drain of the P-channel MOSFET; continuous drain current is -500 mA at TA = 25 °C and pulsed drain current is -1500 mA. |
