A usual datasheet rating for maximum allowed input current into opamps is 10 mA. Initially I thought that this is some kind of DC limit of what the clamping diodes could handle before thermal destruction. I thought that this can be exceeded if the fault is short e.g. a few ms.
However then I learned that silicon latch-up could be the issue if the input current (and thus voltage) reaches a critical level even momentarily.
But during ESD the input current can be much higher without causing permanent damage. At least this is what I assume if opamps claim an ESD rating in their datasheet.
So the question is: can the input current be exceeded for transients? And if so for what approximate duration?
