FDN028N20-HXY

HXY MOSFET · MOSFETs · SOT-23-3L

FDN028N20-HXY from HXY MOSFET, 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; controls the channel, with gate-source voltage limited to ±12 V and RDS(ON) specified at VGS=4.5V and 2.5V (threshold 0.5 to 1.0 V).
2 D passive Drain; drain-source voltage rated 20 V with continuous drain current of 6 A at TA=25℃ and 15 A pulsed.
3 S passive Source; connects to the source terminal of the N-channel MOSFET and the body diode forward current is rated up to 4.5 A.
