YFW2302B

YFW · MOSFETs · SOT-23

YFW2302B 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 ±12 V, with threshold VGS(th) of 0.52 to 0.9 V at ID=250 µA.
2 S passive Source; body-diode continuous current up to 3.0 A and drain-source voltage rating of 20 V.
3 D passive Drain; continuous current 3.2 A at TA=25°C (pulsed 14 A) with VDS rating of 20 V.
