SE2302U

SINO IC · MOSFETs · SOT-323

SE2302U from SINO IC, in a SOT-323. 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; gate-source voltage is rated at ±8 V maximum, with a gate threshold of 0.6 V min to 1.2 V max at ID=250 µA.
2 S passive Source; continuous drain current is rated 2.4 A (9 A pulsed) and the maximum continuous body-diode forward current is 1.6 A.
3 D passive Drain; drain-source voltage is rated at 20 V maximum, with RDS(ON) below 60 mΩ at VGS=4.5 V.
