Metal oxide Varistor / Zinc oxide Varistor ndiyosagwirizana ndi mzere wogwiritsa ntchito ngati semiconductor electrocnic ceramic element makamaka yopangidwa ndi zinc oxide. Amatchedwa varistor kapena mental oxide varistor (MOV), monga momwe zimakhudzira kusintha kwamagetsi. Thupi la varistor ndimapangidwe amtundu wa zinc oxide particles. Malire a mbewu pakati pa tinthu tating'onoting'ono amafanana ndi mawonekedwe amagetsi amitundu iwiri ya PN. Magetsi akamakhala ochepa malire amtunduwu amakhala pamtunda wa impedance ndipo voliyumu ikakhala yayikulu adzakhala mgulu lakuwonongeka lomwe ndi mtundu wa chida chopanda mzere.
