Default Dead? - 5v 800mA

O well my 445 A-140 died after i run it on 5.0 volt 800mA
How can this happen ? any1 ?

800mA doesn't seem too high. Did you have it heat sinked? What driver were you using? Any run time at all?

Default Re: Dead? - 5v 800mA

the heatsink i used is 250 gram beast and it never reached a high temp 25.C maybe 30.C

the big hole is 12 mm the smaller 1 was where i put the diode for max cooling eff. it never reached more then 30.C

Power Supply i used was a labby
well i guess i order a new diode not much to do it's just weird ...

But as i saw mine shine and i was not that satisfied about the brightness of it and as i red earlier that the 130 diode isn't that bright as the 140 i think i got a 130 instead of a 140

The 130 is plenty bright. Correct me if i am wrong laser gods but it only takes like 5% more power for the 130 to put out 1000mW's (when compared to 140). At 800mA you'll still be getting around 750-800mW of power. Power graph for 130 3x 445nm LD PIV Plot

You should of easily been able to see the beam in a dim area and the dot should of been bright enough to illuminate a dark room.

Maybe your diode got damaged by static?

yes it was bright enough to illuminate a dark room beam visible anywhay maybe it was static.
I'll order a new 1 and be even more carefull working with it , any suggestions who can provide me a new 140 ?

Default Re: Dead? - 5v 800mA

What was your power source?

Also, 5V is pretty high for 800mA. IIRC, the diode needs ~3.9-4.1V at that current.
Static is not likely.

If your power source was not clean, a spike may have damaged your diode.

well the diode still emits blue light but verry low and it still eats 650 mA @ 3.6 volt
( led driver) so i guess there was a spike when i ren it @ 5volt ( aka i blew it )

Default Re: Dead? - 5v 800mA

At 5V no way you were only pushing 800mA. Look at the V-I curves for that diode. Just because your multimeter sampled 800mA at some point in time means nothing. A fraction of a second later it could have been 1800mA and burned out the diode.

Which was it, 5V or 800mA? Because it couldn't have been both. Was it a voltage source set to 5V, or a current source set to 800mA?

Please describe your set-up.

Default Re: Dead? - 5v 800mA

Yeah, that's your problem. Look at the I-V curve of these things.

5V will give you WAY more than 1A of current. I haven't even seen a plot up to 5V. You'd be much better off with a current-source driver set to your desired current (800mA) than a voltage-source driver.
