  • Conbined tubular metal oxide varistor and gas discharge tube
    Patent number: 11043317
    Abstract: Provided herein are protection devices having a tubular ceramic part and a tubular metal oxide varistor (MOV) electrically coupled in series or parallel. In some embodiments, the tubular ceramic part is connected between a first electrode and a second electrode, and the tubular MOV is connected between the second electrode and a third electrode. In some embodiments, the tubular ceramic part and the tubular MOV have a same or similar shape and/or outer circumference. The protection device further includes an enclosure surrounding the tubular ceramic part and the tubular MOV, wherein the first electrode, the second electrode, and the third electrode each have leads extending outside the enclosure. In some embodiments, the tubular MOV includes a central cavity aligned with a central cavity of the tubular ceramic part, wherein the central cavity of the tubular MOV MOV and the central cavity of the tubular ceramic part contain an inert gas.
