Is there a big difference between these 2 diodes?

[NeedsMoreFlux]

I'm trying to figure out why the axial diode blew out another chip that I still have not been able to identify.

These are both 1n5819.

I pulled one like this(which I believe was a 1n5819):

and replaced it with one like this(off ebay):



I checked and did not find any shorts/bridging from the new solder joints.

And now I am trying to figure out what this 8 legged, SOIC 8/Sop 8 AN3102 chip is, since that appears to be a chinese number.

If anyone knows what that AN3102 number means or is replaced with, I will be forever in your debt. And I have a big box of spare parts if you ever need anything.

Thank You!

5817 is only rate at 20V, 5819 is rated at 40V so you should never go with lower Voltage than the original.

Oops, haha. I don't know how that happened. I clicked on a 5819, at least I think I did!

But yah, thanks. I was reading up on those different diode numbers.

I did order 5819's off ebay, and after soldering it in-it blew another chip!
