Bridge Rectifier help

[bones]

Hi, I have a blown bridge rectifier, it is a kbpc8-02 which is an 8amp 200v unit. My question is can I use a kbpc8-08 instead ? This is an 8amp 800v unit, does it work like capacitors in that as long as the voltage rating is higher it will work ok or is the voltage rating critical with bridge rectifiers?

I probably should of said that the bridge itself is is just sending 9.9volts to a 5volt voltage regulator and the ac input voltage is no more than 11v

It should be fine.
Sometimes higher voltage versions of semiconductors have lower current ratings, or more losses, but they all look the same for that range.

Thanks John, for some reason the higher rating one is cheaper than the original.

As John said should be fine , Just a ' Smoothing unit ' basically. The caps will be higher rating no no issues there its not like your overloading it.

Just to add, I recently rebuilt my Defender cocktail power supply using uprated voltage and amp rectifiers and all working fine.
