How to choose capacitor voltage rating for ESD protection?
$color{red}{boxed{^1}}$ 195 volts is a little high due to the liberty I took when reducing the 50 MΩ resistor to 100 kΩ. I took this liberty to speed up the 150 pF charge time so that the sim result was more easily viewable. In reality, with basic charge redistribution from the 150 pF capacitor to the 10 nF capacitor, the peak voltage would …

18.4: Capacitors and Dielectrics
On the other hand, the dielectric prevents the plates of the capacitor from coming into direct contact (which would render the capacitor useless). If it has a high permittivity, it also increases the capacitance for any given voltage. The capacitance for a parallel-plate capacitor is given by: c=ϵAdc=ϵAd

Capacitive Reactance
Therefore, it can be seen from above that as the frequency applied across the 220nF capacitor increases, from 1kHz to 20kHz, its reactance value, X C decreases, from approx 723Ω to just 36Ω and this is always true as capacitive reactance, X C is inversely proportional to frequency with the current passed by the capacitor for a given voltage …
Capacitance Calculation
The capacitor has been chosen as 4700 μF to ensure that the input voltage ripples do not exceed the maximum level when duty ratio or load are changed.The output and input voltage capacitors have effect on dynamic response at the irradiation and the load variations whereas increasing these capacitors leads to the slow response.
