FDN339AN-SL

Slkor SLKORMICRO Elec · MOSFETs · SOT-23

FDN339AN-SL from Slkor SLKORMICRO Elec, 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 G input Gate; gate-source voltage is rated ±10 V maximum, with threshold VGS(th) of 0.4 V min to 1.5 V max at ID=250 µA.
2 S passive Source; continuous diode forward current is rated 3 A and the source-drain forward voltage is 1.2 V max at Is=3.0 A.
3 D passive Drain; drain-source voltage is rated 20 V, continuous drain current 3 A, and pulsed drain current 20 A, with RDS(on) of 35 mΩ max at VGS=4.5 V.
