Diode Graveyard

In the interest of attempting to keep track, I'm starting this thread for people to post a memorial of their diodes as they die. Please include such facts as:

Type of diode

Operating current at time of death

Whether or not heatsinking was present

Type of installation (pointer, lab-style)

Driver used

Approximate number of hours before death



Hopefully after a bit of data has been added here we'll begin to get to know the real characteristics of each type of diode.

Let's see how it goes...


(I couldn't find another thread like this but if there is one out there, please let me know.)



I guess I should include mine:

All of my diodes have been driven by my own well-filtered LM317 driver.

2X PHR One at 120mA in just an Aixiz module, the other was part of a lab-style laser. The first died from overcurrent after about 25 hours, the labby died after several hundred hours at 90mA due to a bad connection.

2X LPC Both were in lab-style heatsinks. One died after about 120 hours at 275mA from a bad connection, the other died after a shard of metal broke off the inside threads of the Aixiz module and scraped the die.

1X 5.6mm 808nm 200mW diode in an Aixiz module when a pin fell off of it. It lasted about 10 hours. I can only assume this was a casualty of the extraction process that it underwent.


EDITed

4 X senkat (stonetek) red all 300mA in a Pocketpal with Jayrob's heatsink. I used the flex drive. They probably died from something shorting out. It was my first build :-[

1 X phr 125mA. In a pen style host (no extra heatsinking) with flexdrive (the diode came messed up though. 2 of the 3 pins were broken off... )

10? X Ir diodes from the Phr sleds and the lpc sleds. No heatsinking (besides the one they came in). All hooked up to 2 AA batteries. Lasted very long just got bored and threw them into my diode graveyard. They are tough diodes

? X LCC diodes. Probably died from static ;D

PHR, 150mA, No, In aixiz only, LM317
PHR, 150mA, Yes, home-lathed "pocket pal", DrLava


First one was my first violet, overheated or overcurrented, was too much of a noob to really know.
Second one was in a host, I took it apart and damaged a pin.


More to follow

Just killed this red diode from the SF-AW210 sled. Pocket Pal host w/heatsink. Daedal style driver w/o potentiometer. After checking the ohm reading on my multimeter (4.2), it should have been around 298mA's.

Edit: checked on DMM and it read 330mV (mA) at first, then settled down at 318mV. I guess I should've used a test load. My other red (SF-AW210) is doing fine at 300mA on a V4 driver.

Hehe I made a thread like this a while back...

I dont know where the pics are but I think they are in the thread... Lemme see...

EDIT: cant find it... :-/ I think it may have been like 8 months ago

Hey I like this idea. You read all over the forum how their diodes are working great at XXXmAs. You don't hear to much about the dead ones. With enough info on the dead diodes, the currant, and how long they lasted at said currant, I think some significant info can be found on longevity.

I'd move this to the General section...

Good idea! I should have started it there first. I'll try to get ahold of c0ld to move it..

I have had  

1x phr     @ 135mA 6 hours $15
2x AW210? 6x         @ 185mA 10 min run time and @170mA 1 min run time $120
1x O-Like Nichia     @ 180mA for 40 min run time $85
2x 650nm 20x Diode       @380ma ran for 1 min / @350mA ran for 2min $30

Die on me.    
Total price of $250

ALL of them where Heat Sinked and all of them used a Flexdrive v4 for the driver and all of them in my version of the pocket mini.

I lost a PHR, trying to get it into the AxiZ module. And I suspect that the 4-pin is dead too, after all the times I practiced pressing it in, then took it out by putting a nail into the window.

Several PHR diodes, but only one due to current overdose :
Lasted about 5 months in my Sonar at 160mA, average 20 minutes a week?

Bump..

just keeping it visible..

Only one PHR, at 100mA. But it was only in when I soldered it to my Rkctsr driver that it died, all 3 pins ripted off, because of abusive twisting of the pins. Price of the lost : 0$, I was supposed to receive a LPC, but the guy messed up and I received the wrong sled, that he donated me. The diode ended up crushed in my vice, from frustration. It got replaced by the original diode immediately after it died.

^I may send a few off to you.. PM me with your contact info.

I lost 1 PHR in a Dorcy Jr. with heatsink due to over powering it (~120ma) it lasted about 10 minutes and then LEDed.
I may have just lost a GGW-H20L 6x diode possibly due to uninsullated connections. Further testing is needed to determine whether its the diode or the driver. Driver was set to 220ma. This is also in a Dorcy Jr. host (as a matter of fact the very same one the PHR was in).

1 PHR @ 132.4 mA up from 125.7 mA cause I couldn't dial it back in on the new rckstr, around 10 hrs. run time.

Great name, I love it. :crackup::crackup::crackup::crackup::crackup:
