Breakdown voltage is the voltage at which the insulating dielectric material between the capacitor plates breaks down and conducts electricity.

In series: Breakdown voltage = 2 * Vb
(but only if the capacitances are equal!)

In parallel: Breakdown voltage = Vb

...where Vb is the breakdown voltage of the capacitor, and assuming Vb is the same for both capacitors.
