Mitsubishi 300mW - Died at 1A?

Interesting. But mine wasn't even below freezing - it was probably at 40 F or so (refrigerated), and that is within normal operating conditions.

Ah, we've seen this before. Condensation in the can.

But see, it couldn't even have been that. First, the humidity here is REALLY low (Arizona ) second, it wasn't even that cold. I just use it as a large heatsink, essentially (sucks away the heat to bring the ~40 degrees up to room temp.

But you may be right.

I've seen on the forum 3 LOCs die shortly after they were cooled down by either the fridge, or freezer. But obviously there is no way to be sure.

What would be a safe current for these diodes when they are in a heatsink and have a tec running?(but no air cooling)

 

[Blord]

You always need active cooling with a TEC. That thing is producing far more heat than the diode itself.
