ST2305A

STANSON Tech · MOSFETs · SOT-23-3L

ST2305A from STANSON Tech, in a SOT-23-3L. 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 VGSS is limited to ±12 V.
2 Source passive Source of the P-channel MOSFET; continuous source (diode conduction) current IS is rated at -1.6 A.
3 Drain passive Drain of the P-channel MOSFET; continuous drain current ID is -3.5 A at TA=25℃ (-2.8 A at TA=70℃) with drain-source voltage VDSS of -20 V.
