Default Ringing Mosfets

Hello Class d builders,

Can anyone recommend some power mosfets for my class D-amp.
Im using an hip4081a to dive my H-bridge and that is driving an 8ohm load at about 50W. My switching frequency is around 100kHz and i need as little ring from the mosfets as possible.

I am using some Ir510s as my Mosfets at the mo but there are so many on the market I don't know what to upgrade them to!

Thanks for your time,
Rog

Hi Rog.

The digital Panasonic XR10 use IRFIZ 24 N
and the Sony S Master STRDB 2000 use SUP18N15.


Hope it helps.

Regards
