In Reply to: RE: Upgrading 1N4003 diodes to Stealth 8 amp 600v. posted by Lew on August 19, 2016 at 10:23:30
I've got some Schottky diodes that are 3 amp but, only rated 100v. and I think, the 1N4003 are rated 200v. I may just order some Schottky diodes along with some upgrade ps. caps once I get inside and see what I'm dealing with. Thanks Lew!

Can some please, recommend a Schottky diode of the same or slightly higher values and physical size and package type as the 1n4003 diodes since they are so, close together on the circuit board? Thanks!
Have a look, this may fit your needs.
Both companies have great websites where you can find Schottkys or any other diodes they carry or capacitors or resistors, etc, etc, by using their on-line filters. For example, you would type in "Schottky rectifier diode" and find that they have hundreds if not thousands of different types in terms of amps and volts. Then filter for the amperage and voltage you need, and you will narrow it down to a manageable bunch of choices. If you're looking for a particular brand, Cree is good but so are most others. When it comes to voltage rating, if you are using the diodes in a bridge (4 rectifiers connected head to head and head to tail) then you usually want 2X the highest voltage that will appear. If not in a bridge, 3X is a better safety margin for voltage.
