Question PQFN 5X6mm Packaged N channel Power Mosfet in ClassD ...

Hello ladies and gentlemen ...

First sorry for the faulty english ...

Today by mistake I stumbeld uppon IRFH5020 from international rectifier.
It is presented to be a very fast and powerful yet very small packaged Power Mosfet.

It's main caracteristics are:

Vds = 200V
Rds(on) = 55mOhm
Id = 43A
Qg = 36nC
Qsw = 13nC
Ciss = 2290pF

Internal Diode:

Vsd = 1.3V
Trr = 49nS
Qrr = 97nC
di/dt = 500A/uS

This data was taken from it's datasheet:
http://www.irf.com/product-info/data...rfh5020pbf.pdf

And now the million dollar question:

Can this be used for Class D with good results?

The package beeing surface mount brings a lot of advantages concidering class D PCB requirements.

So ... what is youre opinion Diy'ers?

Best Regards,

Savu Silviu
