ST2305

STANSON Tech · MOSFETs · SOT-23

ST2305 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; gate-source voltage is rated VGSS ±12 V (absolute maximum).
2 Source passive Source of the P-channel MOSFET; continuous source current (diode conduction) is rated IS -1.6 A.
3 Drain passive Drain of the P-channel MOSFET; drain-source voltage VDSS -20 V, continuous drain current -3.5 A at TA=25°C (-2.8 A at TA=70°C), pulsed drain current -10 A.
