Abstract
Integrated device having GDT and MOV functionalities. In some embodiments, an electrical device can include a first layer and a second layer joined with an interface, with each having an outer surface and an inner surface, such that the inner surfaces of the first and second layers define a sealed chamber therebetween. The electrical device can further include an outer electrode implemented on the outer surface of each of the first and second layers, and an inner electrode implemented on the inner surface of each of the first and second layers. The first layer can include a metal oxide material such that the first outer electrode, the first layer, and the first inner electrode provide a metal oxide varistor (MOV) functionality, and the first inner electrode, the second inner electrode, and the sealed chamber provide a gas discharge tube (GDT) functionality.
