    Connecting the two diodes back to back in series, used them to replace a bidirectional transient suppressor diode that shorted in a dishwasher.

        Comments about RadioShack 3-Amp Diodes:

        Regarding the comment below about incorrect part packaged with 600 PIV rather than the proper 200 PIV part:For the most common use of this type of diode, rectification or polarity protection, the actual PIV rating is irrelevant as long as it meets or exceeds the rating of the part you actually wanted. In fact it's generally better to have an overrated part. A diode used for rectification should ideally have a PIV rating of at least 4 times the AC voltage applied.Yes, there are times when you want a specific PIV to take advantage of the avalanche effect, but you likely wouldn't be using this diode in those cases.That said, above 400 PIV most diodes do get a bit slower, but again for the intended use of this type of diode that is irrelevant. If speed is important, such as in SMPS, you want Ultra Fast diodes, such as UF4004 for low power applications.I do agree however, that what's in the package should be what the package claims.

        Could You Package The Right Parts ?

            Comments about RadioShack 3-Amp Diodes:

            The packages indicate that (2 or 3) 1N5402 diodes are enclosed. I purchased 3 packages and there was not a single 1N5402 in the bunch. 1N5402 has a PIV of 200. The 1N5406 that were enclosed in all of the packages has a PIV of 600.
