YFW3404B

YFW · MOSFETs · SOT-23

YFW3404B from YFW, 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 limited to ±20 V, with a threshold VGS(th) of 1.2 V min, 1.5 V typ and 2.5 V max at ID=250uA.
2 S passive Source; the body diode runs from source to drain with a continuous forward current IS of 4 A max and VSD of 1.2 V max.
3 D passive Drain; drain-source voltage rating is 30 V, with continuous drain current of 5.8 A at TA=25°C and RDS(ON) of 29 mΩ typ and 38 mΩ max at VGS=10V.
