The insulation material used in solid-state relays has defects known as internal voids. This allows for localized ionization, the process by which an atom gains a negative or positive charge by losing or gaining electrons when a high voltage rating is applied. As a result, the dielectric strength of the insulation material can breakdown, thus reducing the isolation rating of the device. This process is known as partial discharge (PD), and is applicable to most solid-state relays.
