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
