diode substitution question

[b]

I am currently repairing a Thomson Tv icc7. Amongst other things, I
found a shorted diode BY13/600 in the PS. Can this be substituted with
1R 30D1 4J diode? (at least for test purposes). They are of similar
size and dimensions but I don't know their exact values.
Just curious.
regards, Ben

It will definitely be a 600V PRV rectifier and the current rating will
most likely be 1.5 or 2 A and it will be a fast recovery type. As long
as you use a device which has equal or better ratings then you will be
ok. I suggest you use a BY299 or FR206 or similar device to the specs
shown here

Use Google and search for '800v 2a fast recovery' and you will get
heaps of hits for other possibles.

oops that should read: BYT13 /600 (fast recovery diode)
