Laser Diode pin out, as viewed from the back to make life simple for all.

[andyf97]

So each time I need to test a diode, I keep having to look all over for its datasheet and as these are often a little confusing so I though to start this thread. If we all populate it, it will help everyone else too.

It would be good to add a consistent title like : "445 9mm pin out and connection" so I am going to start with exactly that.

Please keep to the format as in the title and red + and black - on your photos.

P.S. Decided to add a template to make this uniform and easy to update. Just download the template, add the connections and re-upload it with the model name.

Notes, this diode has 4 notches but this does not mater if you keep your relationship to the pins only.

GREAT idea - thanks for posting this!!

Maybe it would work best to list several different configurations and the diodes that go with them. Like this. You could just copy them back to the OP when verified to be correct.

Also if someone could fact check me on the Opnext diodes. I took this off the data sheet but I don't remember the 250mW being Case/LD negative and the 170mW is listed as case neutral.



Case neutral

M140/A140/H1600 445nm
PL450/PL450B 450nm
ML520G71 300mW 635nm
ML501P73 500mW 635nm
ML520G54 110mW 635nm
HL63133DG 170mW 635nm
12X S06J 405nm
8X BDR-S03 405nm
8X BDR-203 405nm
6X GGW-H20L 405nm
4X SF-AW210 405nm
PHR-803T 405nm










Case/LD Negative

HL6388MG 250mW 635nm
HL6385DG 150mW 635
Sanyo 20mW 635nm
Sanyo 40mW 635nm
BDR-203 660nm
BDR-205 660nm
ML101J27 660nm
LPC-815(LOC) 660nm

Yep DTR, I was thinking the same too, but it takes someone to validate them. I am validating them as I test then uploading the data to be as 100% as possible with power and specs.

Hey guys, when you get this finalized I Will Add this to the wiki. Or you guys can do it.. Feel free to add stuff..

Hey chad, I was thinking the same, but better to wait until its more populated and correct, then you can take the data over. Just need to get more people contributing to the real data so feel free to promote also this thread.

Just updated the specs of the osram.

You should probably explain that the minus (negative) sign in red means the positive terminal (anode). It's visually confusing and should probably be changed to a plus sign.

good point, i will change it.
