Need help - Fet replacement Alpine MRV1505

[silversweden]

Hello!
Two of the DC-DC drive Fets is smoked in my Alpine MRV-1505 amp

MTAJ30N06E is the part number.
Cant find this part anywhere, here is a datasheet.

What Fet could i replace those with? Some IRF maybe?
There must be parts with much better specifications since this
is an quite old amp.

I know to look for Max voltage and Max DC/Peak Current.
What more Important specs should i look at compared from
the datasheet?

Im not so familiar with Fets so some help finding a good
replacement would be nice.
The Fets (6 of them paralelled) are driven by a IC.

The Outputs read OK so i cant get why two of the Drive Fets
smoked, maybe its no fault and they smoked from overheating?

I use IRFIZ44Ns (note the second I) when I need fully encapsulated power supply FETs.

Look for broken solder connections in the drive circuit (IC to FET). Do this for both banks of FETs in the power supply.
