FSS2302

FOSAN · MOSFETs · SOT-23-3L

FSS2302 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 absolute maximum, with a gate threshold of 0.55 V min, 0.78 V typ and 1.1 V max at ID=250 µA.
2 S passive Source; continuous drain current is 3.5 A at TA=25 °C and the body diode forward drop is 1.2 V max at ISD=3 A.
3 D passive Drain; drain-source voltage is rated 20 V, with 3.5 A continuous and 12 A pulsed drain current.
