PJA3441 from PANJIT International, 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 limit is ±20 V, with threshold VGS(th) of -1.0 V min to -2.5 V max at ID=-250uA. |
| 2 | S | passive | Source of the P-channel MOSFET; body diode continuous forward current IS is -1.0 A max. |
| 3 | D | passive | Drain; drain-source voltage is -40 V max and continuous drain current is -3.1 A (pulsed -12.4 A). |
