Semudziyo wekudzivirira, machubhu eTVS anogona kudzivirira zvinobudirira kuparara kwemagetsi uye kudzivirira maseketi.Paunenge uchisarudza TVS machubhu, kutarisisa kunofanirwa kubhadharwa kune avo akakodzera paramita, zvikasadaro matambudziko asingatarisirwe anogona kuitika.VRWM, VBR, Vc, Ipp, Cd zvakakosha paramita yeESD/TVS sarudzo yemuchina.
Tsanangudzo:
VBR: Iyo poindi iyo inodonha voltage @ IT - TVS ipapo inova yakaderera impedance
VRWM: Chengetedza magetsi - TVS iri muchimiro chisiri-conductive panguva ino
VC: Clamping voltage @ Ipp - Clamping voltage ingangoita 1.3 * VBR
VF: Forward conduction voltage @ IF - Forward voltage drop
ID: Reverse Leakage Current @ VRWM
IT: Yedza ikozvino yekudonha voltage
IPP: Kuputika kwepamusoro ikozvino
IF: Forward conduction ikozvino
Kana iyo pulse peak ikozvino IPP ine nguva ye20mS inoyerera kuburikidza neTVS, iyo pulse voltage inosungirirwa neESD kudzivirira mudziyo, uye yakanyanya peak voltage inoitika kumigumo yese iVC.VC uye IPP inoratidza kuwedzera kudzvinyirira kugona kweTVS.(Ongorora: VC ndiyo voltage inopihwa neiyo diode munzvimbo yakachekwa, kureva, voltage kuburikidza neTVS panguva yeESD impulse state.Iyo haigone kuve yakakura kupfuura inobvumirwa muganhu voltage yedunhu rakachengetedzwa, kana zvisina kudaro mudziyo unotarisana nenjodzi yekukuvara.).
Maximum Reverse Leakage Current @ VRWM
VRWM inoratidza kuti pasi peID yakataurwa, kukosha kwevoltage kumativi ese eTVS mudziyo inove iyo yakanyanya kureverse inoshanda voltage.Kazhinji VRWM=(0.8~0.9) VBR.Pane iyi voltage, kushandiswa kwesimba kwechigadzirwa kudiki kwazvo.(Cherechedza: Pakusarudza mhando, Vrwm haifanire kunge yakaderera pane yakajairika kushanda voltage yemudziyo wakadzivirirwa kana wedunhu. Kazhinji, VopONUmidziyo inowanzo 12V, uye TVS chubhu inowanzosarudzwa kudzora VC pakati pe14V ne16V.
Iyo voltage iyo iyo TVS transistor inopfuura iyo yakatsanangurwa bvunzo ikozvino Iyo, inova yakanyorwa voltage inoratidza conduction yeTVS transistor, kureva, kubva panguva ino zvichienda mberi, mudziyo unopinda kuparara kweavalanche.VBR ndiyo idiki yekuputsa voltage yeTVS, uye pa25 ℃, TVS haizosangana nemavhairasi pazasi pemagetsi aya.Kana TVS ichiyerera neyakatsanangurwa 1mA yazvino (IR), voltage inoiswa pamatanda maviri eTVS ndiyo shoma yayo yekuputsa voltage VBR.Kuti zvizadzise chiyero chepasi rose cheIEC61000-4-2, maTVS diode anofanirwa kubata hushoma hwe8kV (contact) uye 15kV (mhepo) ESD zvinokonzeresa.Vamwe vanogadzira semiconductor vakashandisa yakakwirira maitiro ekupikisa zviyero pane zvigadzirwa zvavo.Kune mamwe maapplication emudziyo anotakurika ane zvakakosha zvinodiwa, vagadziri vanogona kusarudza zvishandiso zvinoenderana nezvavanoda.
Zviri pamusoro apa ipfupi pfupiso yeInokosha Parameters yeTVS Selection, inogona kushandiswa sereferensi.Kambani yedu ine yakasimba tekinoroji timu uye inogona kupa nyanzvi tekinoroji masevhisi kune vatengi.Parizvino, kambani yedu ine zvigadzirwa zvakasiyana-siyana: zvakangwaraonu, kutaurirana optical module, optical fiber module, sfp optical module, olt midziyo, Ethernet switch uye zvimwe network michina.Kana uchida, unogona kuzvinzwisisa zvakadzama.
