Why not just pop for a diode with the required voltage & current capability and get it over with? Some stud mount model will likely do it.
The OP asked for 220V AC to 220V DC rectification in the first place.
Second wish is 15A.
He then linked to a 1A/1000V diode.
There is no such thing (220V AC to 220V DC rectifier). Even when a diode or bridge rectifier were used with 400V/16A rating there would still not be a 220V DC there would be 310V DC.
If he truly wanted this there would be the need for DC regulation and loosing 90V with 15A would require a
1000 W regulator.
That is not something one can feed (audio) electronics with anyway.
I understand that for someone starting out with electronics this seems logical but even a basic google search will show one the basics of rectification.
