DO2309A

DOINGTER · MOSFETs · SOT-23

DO2309A from DOINGTER, 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 V to -2.5 V.
2 D passive Drain; drain-source voltage -60 V max, continuous drain current -2 A at TA=25℃ and pulsed -8 A.
3 S passive Source of the P-channel MOSFET; the body diode is connected from drain to source, with continuous diode current -2 A.
