I have a 220nF capacitor in a series with my surge protection circuit.
As can be seen from my spice simulation, the capacitor gets a surge of current passing through it under fault conditions, and ideally, I don't want the capacitor to explode. From looking at capacitor datasheets, surge current and power capacities of capacitors are unclear.
How do I go about selecting a capacitor for my application?
-------Requested additional information--------
For simplicity, I have cropped the schematic to show where the capacitor is located. The Surge comes from the primary of the transformer(left) which has some leakage attached (L4 & L5). The transformer is 1:1 and has two ohms series resistance.
When the surge comes through, the output TVS clamps through the capacitor.
