SQ2309ES-T1_GE3

Vishay Intertech · MOSFETs · SOT-23

SQ2309ES-T1_GE3 from Vishay Intertech, 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 of the P-channel MOSFET; the absolute maximum gate-source voltage is ±20 V.
2 S passive Source of the P-channel MOSFET; the continuous source current (diode conduction) is limited to -2.6 A.
3 D passive Drain of the P-channel MOSFET, which also serves as the thermal connection from the package to the PC board; the drain-source voltage is limited to -60 V.
