ATM3407PSA from Agertech, 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) of -1.0 V min to -2.0 V max at ID=-250µA.
2	S	passive	Source of the P-channel MOSFET; carries up to -3.7 A continuous drain current at TA=25°C.
3	D	passive	Drain, the single lead on the opposite side of the package; drain-source voltage rated at -30 V and pulsed drain current -15 A.
