SP2102CT3

Siliup · MOSFETs · SOT-323

SP2102CT3 from Siliup, 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 limited to ±10 V absolute maximum, with threshold VGS(th) of 0.5 V min to 1 V max at ID=250µA.
2 S passive Source; continuous drain current is 1.8 A (pulsed 7.2 A) from drain to this pin.
3 D passive Drain; drain-source voltage is rated at 20 V maximum (BVDSS 20 V min at ID=250µA) with RDS(on) of 60 mΩ typ at VGS=4.5 V.
