| Mar 28, 2023 at 13:16 | comment | added | greybeard | And my take is: Why bother where I expect things like temperature and variance of instance parameters to dominate? While I wouldn't know about ageing of semiconductors beyond Arrhenius, I expect device/specimen history (has seen non-destructive ESD, breakdowns with limited current - you name it) to play a significant role. | |
| Mar 28, 2023 at 13:02 | comment | added | James Strieter | @greybeard Forgive my ignorance, but I'm not sure how this article speaks to the time stability of leakage current. Another way to ask the question is, "Are the statistics of SCR leakage current stationary?" | |

| Mar 26, 2023 at 12:58 | comment | added | James Strieter | @greybeard sorry for the delayed reply. I am trying to find out if I measure leakage as 10 mA (or whatever) at the factory, is leakage likely to stay roughly the same for at least 2 years? | |
| Mar 23, 2023 at 12:01 | comment | added | greybeard | For a sum of rated voltages of 7.2 kV, a nominal voltage of 6.6 kV is what I call uncomfortably close: consider 10% over-voltage, and the split being uneven about 15%. For leakage current, take a somewhat comprehensive datasheet and look for graphs involving it, and table entries stating both min and max. | |
