Do you know this for sure? What are the physics involved? If I exceed Imax, 
the bond wires will start to melt or something?

This is not for any particular project, just something I recently bumped 
into -- but it bothers me that I don't understand why it happens and that I 
can't find the answer either on the 'net or in my transistor books.
