Thanks for the input, Cheech.
Here's the latest:
I had time at work today to fire up my brand new Weller soldering station, and get to fiddling with this diode.
When I opened up the host, I discovered that one of the pin connections to the driver looked to have come loose. I was sure it wasn't dry when I made it.
I also took the time to make sure that all of the connections were thoroughly wet-soldered.
None of this seems to have helped. While I had it open, I inspected the window as much as I could with a pathetic magnifier. I didn't see any debris, but there is a distinctive "fog" just barely perceptible around the dot. So, I think that Cheech might be on to something, though it hasn't been long since I cleaned it.
I will take some acetone or 91% alcohol to it tomorrow.
Does anyone know whether I can get this thing a decent life span if I tune it down to below 400mA?
