Yes diode is useful after break down because it flows current from one direction to other direction
A: Believe it or not that is the only time that it is useful
A: Most useful or actually the only time that it is useful is when it has reached its predictable reverse breakdown voltage.
zener breakdown and avalanche breakdown.
Zener breakdown is the phenomena wherein the Zener diode experiences reverse breakdown at a much lower voltage than a normal diode, which may breakdown in excess of 100 volts, depending on the type. This is useful because the Zener will hold the same voltage after breakdown, regardless of the input voltage, making them excellent for voltage controlled switches and references.
A Zener Diode will continue to show its breakdown characteristics until it gets fried...for example a 5 volt zener will get fried at a breakdown voltage of about 6 volts..this happens because of the large amount of current flowing through the small diode which unfortunately the diode cannot handle.

there is no forward breakdown voltage for any diode

Normally too higher voltage burns the diode.
The reverse breakdown voltage of the 1N4007 diode is 1000 volts.

general purpose diode with 1000V reverse breakdown.
A Germanium diode has a much lower breakdown voltage than a silicone diode.
