It would help if we knew what wavelength of diode it is, but i suppose i will just rattle off what i know.

While holding the diode so the back of the can faces you with the uninsulated(grounded pin) at the bottom

RED & IR- Right insulated is (+) and bottom case pin is (-)
VIOLET- Right insulated is (+) and Left insulated is (-)

All I know is that it was Laser Diode out of a dvd rewriter, it was the Red One because it scrapped the IR one from the drive. Anyways all of the pins are uninsulated.

They won't all be uninsulated - all but one is likely to have a plastic section around the base of the pins. Is it a round, 5.6mm diode? Can you perhaps send a pic? If you look on the stickies in the appropriate areas, there are diagrams showing the pin configurations of all common diodes.

Have you tryed typing in the search box "diode pin out" why don'y you try that I just did and found all the info you could ever want ;)

Yeah, i assumed thats what kind of diode he would have, he seems alittle new to be messing with things like c-mounts and TO-3's
Your assumption was a bit risky. I didn't mean c-mount or TO-3. Standard TO-18 diodes also has different pinouts. For example, diodes from pointers (also easily available for beginners and as common as these from optical drives I think) - they usually have anode on the casing.

Yeah i suppose it was :undecided:

Thanks for setting me straight
