Monga chipangizo chotetezera, machubu a TVS amatha kuteteza kuwonongeka kwa electrostatic ndikuteteza mabwalo. Posankha machubu a TVS, chidwi chiyenera kulipidwa pazigawo zawo zoyenera, mwinamwake mavuto osayembekezereka angachitike. VRWM, VBR, Vc, Ipp, Cd ndi magawo ofunikira pakusankha kwa chipangizo cha ESD/TVS
Kufotokozera:
VBR: Pomwe kugwa kwamagetsi @ IT - TVS nthawi yomweyo imakhala yotsika
VRWM: Sungani mphamvu yamagetsi - TVS ili m'malo osayendetsa panthawiyi
VC: Voltage ya Clamping @ Ipp - Voltage ya Clamping ndi pafupifupi 1.3 * VBR
VF: Forward conduction voltage @ IF - Forward voltage drop
ID: Reverse Leakage Current @ VRWM
IT: Yesani mphamvu yamagetsi yakugwa
IPP: Kuphulika kwakukulu pakali pano
IF: Forward conduction current
Pamene nsonga yapamwamba ya IPP yomwe ili ndi nthawi ya 20mS imayenda kudzera pa TVS, mphamvu yamagetsi imatsekedwa ndi chipangizo chotetezera cha ESD, ndipo mphamvu yapamwamba kwambiri yomwe imapezeka pamapeto onse awiri ndi VC. VC ndi IPP zikuwonetsa kuthekera kwapang'onopang'ono kwa TVS. (Zindikirani: VC ndi voteji yoperekedwa ndi diode pamalo odulidwa, ndiye kuti, voteji kudzera pa TVS panthawi ya ESD. Sichingakhale chachikulu kuposa malire ovomerezeka a dera lotetezedwa, apo ayi chipangizocho chimayang'anizana ndi chiopsezo cha kuwonongeka.).
Maximum Reverse Leakage Current @ VRWM
VRWM ikuwonetsa kuti pansi pa ID yomwe yatchulidwa, mtengo wamagetsi kumapeto onse a chipangizo cha TVS umakhala mphamvu yayikulu yosinthira. Nthawi zambiri VRWM=(0.8~0.9) VBR. Pamagetsi awa, kugwiritsa ntchito mphamvu kwa chipangizocho kumakhala kochepa kwambiri. (Zindikirani: Posankha mtundu, Vrwm sayenera kukhala yotsika kuposa mphamvu yanthawi zonse yogwira ntchito ya chipangizo chotetezedwa kapena dera. Nthawi zambiri, VopONUZida nthawi zambiri zimakhala 12V, ndipo chubu cha TVS nthawi zambiri chimasankhidwa kuti chiwongolere VC pakati pa 14V ndi 16V.
Mpweya umene transistor ya TVS imadutsa mayeso omwe atchulidwa panopa Iwo, omwe ndi chizindikiro cha voteji chosonyeza kuyendetsa kwa transistor ya TVS, mwachitsanzo, kuyambira pano, chipangizocho chimalowa kuwonongeka kwa chigumukire. VBR ndiye voteji yocheperako ya TVS, ndipo pa 25 ℃, TVS sikhala ndi mafunde otsika pansi pamagetsi awa. Pamene TVS ikuyenda kudzera pa 1mA panopa (IR), magetsi ogwiritsidwa ntchito pamitengo iwiri ya TVS ndi VBR yake yochepa yowonongeka. Kuti mukwaniritse mulingo wapadziko lonse wa IEC61000-4-2, ma diode a TVS akuyenera kuthana ndi zovuta za 8kV (contact) ndi 15kV (mpweya) ESD. Opanga ena a semiconductor agwiritsa ntchito miyezo yapamwamba yokana pazogulitsa zawo. Pazida zina zonyamulika zokhala ndi zofunikira zapadera, opanga amatha kusankha zida malinga ndi zosowa zawo.
Zomwe zili pamwambazi ndizofotokozera mwachidule Zofunikira Zofunikira za Kusankhidwa kwa TVS, zomwe zingagwiritsidwe ntchito ngati zofotokozera. Kampani yathu ili ndi gulu lolimba laukadaulo ndipo imatha kupereka chithandizo chaukadaulo kwa makasitomala. Pakadali pano, kampani yathu ili ndi mitundu yosiyanasiyana: yanzeruinu, gawo lolumikizana la kuwala, gawo la kuwala kwa fiber, sfp optical module,oltzida, Efanetikusinthandi zida zina zamaneti. Ngati mukufunikira, mukhoza kuwamvetsa mozama.
