These are case neutral.



Paul - can you put this in the first post please? That way it's easy to find

It has been done. Hopefully, this will eliminate these questions in the future. :yh:

I've been gone a long time, but I saw this and I just have to have one. Are there any left, or am I too late?

To get a diode, probably. I think Rich (Lifetime17) has one he is going to put in a build. He may still have the all copper one for sale too. I have a spare diode, but it's not for sale. Sorry.

That's great, Singlemode. I had thought you all out of these diodes you planned to sell. I'm sure someone has contacted Sta by now to let him know.

I got 1 more of these 495nm diodes left i really want to push this last diode so im going to install it in a 20mm copper heatsink with a nano drive at 350ma :D

If you do, I'd keep the run time under a minute as these tend to get hot because the Vf is so high. I'd hate to hear you lost it by running it too long. Even with a 20 mm copper module the heat can't get out as fast and that current is far beyond the recommended current.

Have you seen a data sheet for the GH04955A2G ? Looking for the Vf and current rating.

Thank you, decent radiation angles for both sides, fairly low like a single mode, are they?
