ST2301A

STANSON Tech · MOSFETs · SOT-23

ST2301A from STANSON Tech, 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 Gate input Gate of the P-channel MOSFET; the datasheet rates the gate-source voltage VGSS at ±12 V.
2 Source passive Source of the P-channel MOSFET; the datasheet rates the continuous source (diode conduction) current IS at -1.6 A.
3 Drain passive Drain of the P-channel MOSFET; the datasheet rates the drain-source voltage VDSS at -20 V, continuous drain current ID at -3.2 A (TA=25℃), and pulsed drain current IDM at -10 A.
