Abstract
An overvoltage protection device module includes an electrically conductive first electrode, an electrically conductive housing electrode, and a varistor member formed of a varistor material and electrically connected between the first electrode and the housing electrode. The housing electrode includes a housing end wall and a housing side wall collectively defining a housing cavity, and first and second housing members joined together at a joint. The first housing member forms a first portion of the housing side wall and the second housing member forms a second portion of the housing side wall. The varistor member is disposed in the housing cavity.
