SQ2337ES-T1_GE3

Vishay Intertech · MOSFETs · SOT-23

SQ2337ES-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 Gate input Gate pin (pin 1) controls the MOSFET; gate-source voltage is rated at ±20 V.
2 Source passive Source pin (pin 2) carries the source connection; continuous source current (diode conduction) is rated at -3.7 A.
3 Drain passive Drain pin (pin 3) also provides the thermal connection from the package to the PC board; drain-source voltage is rated at -80 V.
