Need help with MOSFETs on the Robin Z510 board

Good day everyone.

I’m asking for help with identifying two MOSFETs on the Robin Z510 board. They blowed up, and I’m lost part of the marking. I’m see just FDS69 on the one of them, and FDS698 on the other. There is should be 4 digits and maybe a letter (like FDS6984 or FDS6982AS). Anyone, please, help, if you can.

Both of them are FDS6982AS.
However blown MOSFETs indicate some other HW issue and simple replacing may not help.

Thank you for your help!
Yes, I understand, that replacing may not help. But first I need to replace them. There was a surge in the power network. Thank’s again!

You are welcome.

Best regards,
