If you exceed the breakdown voltage, the dielectric or other capacitor material breaks down and it turns into a resistor and could short. I have seen some . , I usually go ~70% of the breakdown voltage. A capacitor will charge up to the supply voltage.
Or was; it probably won't be a very useful capacitor afterward. The cap will try to charge to the supply voltage. On its way to that voltage, if the voltage exceeds the voltage rating of the capacitor, the capacitor will eventually fail. At that point it will be permanently damaged. It may have even externally ruptured.
This phenomenon occurs when the electric field across a dielectric material exceeds its critical limit, leading to the breakdown of its insulating properties. In capacitors, understanding breakdown voltage is crucial, as exceeding this threshold can lead to capacitor failure or damage.
This means that the capacitor is permanently destroyed as a capacitor, even if the voltage is removed. It may test as a short circuit, or it may break down at a lower voltage next time the capacitor is used. Air spaced capacitors are usually not destroyed by high voltage but will arc over if the voltage is high enough.
Basically, when you exceed the rated voltage, as with any other rated component, the capacitor can't handle it and the dielectric will probably melt or something, and cause a short circuit between the plates. This is the only thing I can think you mean by "capacitor breakdown".
The breakdown voltage is also influenced by factors like temperature and frequency of the applied voltage. Different applications may require capacitors with specific breakdown voltages to ensure reliability and performance in electronic circuits.
