Nkigikoresho cyo gukingira, imiyoboro ya TVS irashobora gukumira neza gusenyuka kwa electrostatike no kurinda imirongo.Mugihe uhitamo imiyoboro ya TVS, hagomba kwitonderwa ibipimo bijyanye, bitabaye ibyo ibibazo bitunguranye bishobora kubaho.VRWM, VBR, Vc, Ipp, Cd nibintu byingenzi muguhitamo ibikoresho bya ESD / TVS
Ibisobanuro:
VBR: Ingingo aho gusenyuka voltage @ IT - TVS ihita iba impedance nkeya
VRWM: Komeza voltage - TVS iri mumikorere idahwitse muriki cyiciro
VC: Clamping voltage @ Ipp - Clamping voltage ni 1.3 * VBR
VF: Imbere yo gutwara voltage @ NIBA - Imbere ya voltage igabanuka
ID: Guhindura imyuka igezweho @ VRWM
IT: Ikizamini kigezweho cyo gusenyuka voltage
IPP: Impanuka yo hejuru
NIBA: Imbere yo kuyobora
Iyo impanuka yimpanuka ya IPP ifite igihe kingana na 20mS inyura muri TVS, imbaraga za pulse zomekwa nigikoresho cyo gukingira ESD, kandi n’umuvuduko ntarengwa w’impanuka uboneka ku mpande zombi ni VC.VC na IPP byerekana ubushobozi bwo guhagarika TVS.(Icyitonderwa: VC ni voltage itangwa na diode muburyo bwo guhagarikwa, ni ukuvuga, voltage ikoresheje TVS mugihe cya ESD impulse.Ntishobora kuba irenze imipaka yemewe ya voltage yumuzunguruko urinzwe, bitabaye ibyo igikoresho gihura ningaruka zo kwangirika.).
Ntarengwa Isubira inyuma @ VRWM
VRWM yerekana ko munsi yindangamuntu yagenwe, agaciro ka voltage kumpande zombi zigikoresho cya TVS gihinduka nini ya voltage ikora.Mubisanzwe VRWM = (0.8 ~ 0.9) VBR.Kuri iyi voltage, ingufu zikoreshwa nigikoresho ni nto cyane..ONUibikoresho mubisanzwe ni 12V, kandi umuyoboro wa TVS muri rusange watoranijwe kugenzura VC hagati ya 14V na 16V.
Umuvuduko aho transistor ya TVS itambutsa ikizamini cyerekanwe It, nicyo kimenyetso cyerekana voltage yerekana itwara rya transistor ya TVS, ni ukuvuga, guhera iyi ngingo, igikoresho cyinjira mumashanyarazi.VBR ni ntoya yamashanyarazi ya TVS, kandi kuri 25 ℃, TVS ntizigera ibona inkangu munsi yiyi voltage.Iyo TVS inyuze muri 1mA yagenwe (IR), voltage ikoreshwa kumpande ebyiri za TVS niyo ntoya yameneka ya voltage VBR.Kugirango wuzuze ibipimo mpuzamahanga bya IEC61000-4-2, diode ya TVS igomba kuba ishobora gukemura byibuze 8kV (contact) na 15kV (ikirere) ESD.Bamwe mu bakora inganda za semiconductor bakoresheje ibipimo bihanitse byo kurwanya ibicuruzwa byabo.Kubikoresho bimwe byimukanwa byimikorere hamwe nibisabwa byihariye, abashushanya barashobora guhitamo ibikoresho ukurikije ibyo bakeneye.
Ibyavuzwe haruguru ni incamake yerekana Ibyingenzi Byingenzi byo Guhitamo TVS, bishobora gukoreshwa nkibisobanuro.Isosiyete yacu ifite itsinda rikomeye rya tekiniki kandi irashobora gutanga serivisi tekinike yumwuga kubakiriya.Kugeza ubu, isosiyete yacu ifite ibicuruzwa bitandukanye: bifite ubwengeonu, itumanaho rya optique module, optique ya fibre optique, sfp optique module, ibikoresho bya olt, Ethernet ihindura nibindi bikoresho byurusobe.Niba ukeneye, urashobora kubyumva byimbitse.
