FSS2301

FOSAN · MOSFETs · SOT-23-3L

FSS2301 from FOSAN, 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 G input Gate; gate-source voltage is limited to ±10 V and the gate threshold voltage VGS(th) is -0.4 V min, -0.6 V typ, -1 V max at ID = -250 µA.
2 S passive Source; drain current is rated -3 A continuous and -18 A pulsed at TA = 25 °C.
3 D passive Drain; drain-source voltage is rated -20 V (BVDSS), with RDS(ON) of 81 mΩ typ at ID = -3 A, VGS = -4.5 V.
