DMG3420U-HXY

HXY MOSFET · MOSFETs · SOT-23

DMG3420U-HXY from HXY MOSFET, 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 terminal of the N-channel MOSFET; the datasheet gives the gate-source voltage limit as ±12 V and specifies RDS(ON) at VGS = 2.5 V and 4.5 V.
2 D passive Drain terminal; the datasheet limits drain-source voltage to 20 V and continuous drain current to 6 A at TA = 25℃ (3.6 A at TA = 70℃), with 15 A pulsed.
3 S passive Source terminal; the datasheet gives a diode forward current rating of 4.5 A and specifies the body diode forward voltage at IS = 1 A (1.2 V max).
