Yes those are the extreme circumstances I was talking about. Regardless no matter the specs, there is fixed a voltage between the entry and exit of the semiconductors which will determine the amount of energy it will sustain at any time. That amount of energy is way, way inferior to the energy contained in the chemical bonds, so the chemicals should not react. But there is always an epsilon risk of them reacting and the bigger the total amount of energy it sustains over time the higher that epsilon is of course.
