Diode Identification

I have a diode which I can't seem to find any information on. I've tried all the usual sites and no-one seems to have any matching part numbers.

Its from a LCD monitor power supply - from the recifier circuit (as far as I can tell) - its was connected to a 400V cap which is also blown if that helps any.

On the diode: GP20-06 F51

The logo is a wavy F in a circle.The only company I can find which has a similiar logo is frontier electronics, but they dont make diodes.

Any info would be appreciated.

After some more searching - I found another frontier electronics company

Industrial rectifier by Fairchild. Crosses to an NTE5806, 600PRV-3amp

I'd guess it'll be a fast recovery diode ( maybe 2 amps ? ) with 600V rating.

If that was a 400 volt electrolytic capacitor, and the diode is "small", that likely places the diode on the line-voltage side of the power supply. That makes things a lot easier. It doesnt have to be particularly fast. Just able to handle 2 times 1.414 times the line voltage. So a plain old 1N4007 should work fine.

If it was like a 0.05uF 400 volt capacitor, and the diode is "bigger", like a typical 3-amp diode, then it's more likely on the high-frequency side of the PS. Then you'll need a faster diode. There are tons of them around, check out the 1N51xx line.
