Toasted my first diode.

Well, I guess if everyone will toast n diodes in their life, I can now look forward to only n-1 .

As a friend of mine says, you can't learn anything without breaking something.

I ordered 5 diodes from senkat, within an hour of receiving i had toasted one..... I was putting it directly in a flashlight and while focusing i twisted too much and the positive and negative pins touched..... $30 down the drain....

Popped mine out of the socket that it was mounted in - out & in - maybe 10 milliseconds. Toasted. Now I solder them ALL. So far, only one cooked. Second one going strong. I was watching the spot on CLOUDS last night!

I fried one the same way. It must have come loose for just a millisecond. Turned it on and poof! Bright flash, then LED.

I will also solder them from now on.

Wow, you all have some catching up to do...I have ruined about 20 so far.. ;D And all for varying reasons, even a couple on purpose...I had to see how hard I could drive them. Like xanatos and roSSco, I ruined a few before I realized it was the socket causing the problem. So I solder everything since that happened.

yep ive killed 4, one from getting plastic on the window them my circuit giving to much power and killing it, two from giving them 250ma or suposidly but i never measured so i prob gave it like 400ma nowing my luck, one from it reflecting back into it from the lense i was using, didnt know that would break it.

...lazer... ;D ;D ;D

If the + and - touched, it shouldn't kill the diode, as to the diode it just looks like the current was turned off! More likely you simply burned it out with no driver.

That's exactly how I fried this one.  It was lasing, the leads shorted for millisecond, and when it flashed back on it was just an LED.

Why would touching the pins together, with or without current kill it?

Without current touching is fine. With current, you have to take in to account the transient response of the voltage regulator. It takes some time for the circuit to recover from sudden changes in the load (such as momentarily shorting the LD leads). During the recovery time, the voltage/current can spike in the output.
