when driving heavy inductive load (shorted transformer for example), there can be times, when maximum current thru silicon would be at the maximum voltage on it, so it can explode even with the current being say 5 times less its "explosive" value.
current limiting in such condition is useless - what one can do in that case?

I think that's V^2/R, if the resistance is high and there's a large voltage drop(V part) its a lot of heat.
The thing that confused me was not voltage at that point but the drop across it.
