I worked in the discrete semiconductor industry for 30 years
(engineering, manufacturing, management) and that statement is simply
not true at all.
Zener diodes are designed to break down uniformly across the entire
junction, but most other semiconductors are not. A reverse voltage
breakdown
What kills solid state PN junctions is excessive power dissipation (heat).
You can abuse the breakdown voltage of a PN junction as long as the power
dissipated there is within the power dissipation range of the PN junction.
That's how Zener diodes work and it is why they have a power dissipation
