Tsarin asali na mai kama zinc oxide shine farantin valve.Bawul ɗin zinc oxide an rufe shi a ƙarƙashin ƙarfin ƙarfin aiki, kuma wucewar halin yanzu yana da ƙanƙanta, gabaɗaya 10 ~ 15μA, kuma halayen da ba a taɓa gani ba na bawul ɗin zinc oxide galibi an kafa su ta layin iyaka.Wutar siffar sifarsa ta volt-ampere tana kusa da na mai kamawa.
Baya ga kyakkyawan rashin daidaituwa, masu kama zinc oxide kuma suna da fa'idodi masu zuwa:
1. Babu tazara.A ƙarƙashin aikin ƙarfin lantarki na aiki, farantin bawul ɗin zinc oxide yana daidai da insulator, wanda ba zai haifar da ƙonewa ba.Sabili da haka, yana yiwuwa a ware wutar lantarki mai aiki ba tare da jerin rata ba.Saboda babu rata, zai iya sauri amsa girgizar girgiza tare da kai mai tsayi, kuma fitarwa ba ta da jinkiri, kuma tasirin iyakancewa yana da kyau sosai.Ba wai kawai inganta amincin kariyar kayan aikin wutar lantarki ba, amma har ma yana rage yawan ƙarfin aiki akan kayan aikin wutar lantarki, ta haka ne rage ƙimar ƙimar kayan aikin wutar lantarki.
2. Babu ci gaba da gudana.Daga halayen da ke sama, ana iya ganin cewa kawai lokacin da ƙarfin lantarki da aka yi amfani da shi a kan bawul ɗin zinc oxide ya kai ƙarfin aiki na farko, "gudanarwa" yana faruwa.Bayan “Gudanarwa”, ragowar ƙarfin lantarki akan bawul ɗin zinc oxide daidai yake da na yanzu da ke gudana ta cikinsa.Ba shi da mahimmanci amma ƙimar ƙima.Lokacin da ƙarfin lantarki da aka yi amfani da shi ya faɗi ƙasa da ƙarfin aiki, yanayin "conduction" na bawul ɗin zinc oxide yana ƙare, wanda yayi daidai da insulator.Saboda haka, babu wutar lantarki freewheeling.
