| Nov 5, 2010 at 5:46 | comment | added | Connor Wolf | In most dual TO-220 packages, not only are the diodes thermally coupled together, they are generally both on the same die (e.g. made from the same chunk of silicon, in the same manufacturing run). This means they typically have very closely matching characteristics, which is why it works. | |

| Nov 4, 2010 at 18:04 | comment | added | Nick T | @Kor: Don't diodes usually fail closed? True, it might "open" given enough power, but I'd think it would of taken something else out by then. | |

| Nov 4, 2010 at 3:42 | comment | added | Kortuk | I have a professor who does this often, he will take 1000 diodes, literally, and measure their VI curve. Then he will strain them to have a very precise match. He sorts them into matching bins. Then he keeps them heat-sinking together. | |
