ABSTRACT:
A solid-state surge protection device comprises a semiconductor chip sandwiched between two electrodes. A resilient sealing member or layer comprised of a thermoplastic or thermosetting resin extends around the periphery of the device, adhering to both electrodes, so as to seal the interface region between the chip and each electrode. The resin is a flexible, dielectric material which is not disrupted by heat generated under surge conditions in the device, is environmentally inert, and preferably remains compliant under extremely cold conditions. The electrodes of the device can move together into electric-conductive contact in the event of chip destruction, or can move back into contact with the chip if separated therefrom by an arc.
