NTMFS4C290N-HXY

HXY MOSFET · MOSFETs · DFN-8(5x6)

NTMFS4C290N-HXY from HXY MOSFET, in a DFN-8(5x6). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	S	passive	Source terminal of the N-Channel MOSFET. Pins 1, 2, 3 are internally connected to the source and should be tied together on the PCB to carry the drain current (rated ID=80A @ TC=25°C).
2	S	passive	Source terminal of the N-Channel MOSFET. Internally bonded to pins 1 and 3; tie together on the PCB for full current handling.
3	S	passive	Source terminal of the N-Channel MOSFET. Internally bonded to pins 1 and 2; tie all source pins together on the PCB.
4	G	input	Gate terminal of the N-Channel MOSFET. Gate threshold VGS(TH)=1.0-2.5V (typ 1.7V); absolute maximum VGS=±20V. Drive with VGS≥4.5V for RDS(ON) ≤ 8 mΩ, or VGS=10V for RDS(ON) ≤ 6 mΩ. Total gate charge Qg≈38 nC.
5	D	passive	Drain terminal of the N-Channel MOSFET. Pins 5, 6, 7, 8 (and the exposed thermal pad) are internally connected to the drain; all must be tied together on the PCB and copper-poured for thermal dissipation (RθJA=30 °C/W). Rated V(BR)DSS ≥ 30V.
6	D	passive	Drain terminal of the N-Channel MOSFET. Internally bonded to pins 5, 7, 8 and the exposed thermal pad; tie together on the PCB.
7	D	passive	Drain terminal of the N-Channel MOSFET. Internally bonded to pins 5, 6, 8 and the exposed thermal pad; tie together on the PCB.
8	D	passive	Drain terminal of the N-Channel MOSFET. Internally bonded to pins 5, 6, 7 and the exposed thermal pad; tie together on the PCB for full-current and thermal path.
