UZinc onide Surge Bourners ngumvikeli osekhulile kakhulu ngokumelene namandla amakhulu emhlabeni. Njengoba ukumelana kwe-ZOSA kwenziwa amafilimu we-zinc oxide. UZinc onide SurgeMbhobhoInezimpawu ezinhle ze-voltage-ampere njengoba iqhathaniswa nabakwa-SIC, i-voltage futhi i-flow yamanje isezingeni eliphakeme kakhulu lapho i-ZOSA isebenza ngaphansi kwamandla ajwayelekile, ngoba inani le-ZOSA likhona lapho i-ZOSA ikhathazekile! Izimpawu ezingezona ezilayini. Ngaleso sikhathi uma kwenzeka kubandela ukukhululeka kwamandla kagesi ngamandla amakhulu, ngakho-ke lokho kukhawulela ukulimala kwezidingo zokuhambisa nokuguqulwa.
