RHRP3060 & RURG3060 are 30A, way too big to fit & certainly costly.
BY8C-600 is 8A & hyperfast (30 nanoseconds), also quite a bit overkill.
RL205-T is a 2A standard diode. At least it'll fit, but don't go for a standard one.
RD2004LS has marginal voltage and total overkill current.
I they're not mentioned as being switching devices then they're not. Reverse recovery times below a microsecond starts to be useful.
Look for terms like fast, superfast, ultrafast, & hyperfast. That's the order of their rated "speediness". And there's no need to go much over 1A, better to up the voltage.
How about choosing a supplier first and see if they have something useful. Being in Scandinavia you may have easy access to Elfa. Check them out if so.
