Is there any concept in standard physics of an electromagnetic
equivalent to a black hole?

I observe that in a hydrogen atom the electromagnetic force is ~10^40
stronger than the gravitational force. Also, a proton is ~10^40 too low
in mass to be a gravitational black hole. Therefore if there were an
electromagnetic equivalent to a black hole, a proton would seem to have
the right properties to be one would it not?
