FS4406A

FOSAN · MOSFETs · SOP-8

FS4406A from FOSAN, in a SOP-8. 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 S passive Source of the N-channel MOSFET, tied to pins 2 and 3; the device is rated for ID 25 A at TA=25°C and BVDSS 30 V.
2 S passive Source of the N-channel MOSFET, tied to pins 1 and 3; the device is rated for ID 25 A at TA=25°C and BVDSS 30 V.
3 S passive Source of the N-channel MOSFET, tied to pins 1 and 2; the device is rated for ID 25 A at TA=25°C and BVDSS 30 V.
4 G input Gate of the N-channel MOSFET, with VGS rated ±20 V maximum and a threshold VGS(th) of 1.0 V min to 2.5 V max at ID=250 µA.
5 D passive Drain of the N-channel MOSFET, tied to pins 6, 7 and 8; the drain-source breakdown voltage is 30 V minimum.
6 D passive Drain of the N-channel MOSFET, tied to pins 5, 7 and 8; the drain-source breakdown voltage is 30 V minimum.
7 D passive Drain of the N-channel MOSFET, tied to pins 5, 6 and 8; the drain-source breakdown voltage is 30 V minimum.
8 D passive Drain of the N-channel MOSFET, tied to pins 5, 6 and 7; the drain-source breakdown voltage is 30 V minimum.
