Iimpawu zokusetyenziswa kweTVS transient voltage suppression diode principle TVS transistor

I-TVS-Ifutshane kwiDiode ye-Voltage Suppressor Diode. I-TV sisixhobo sokukhusela i-voltage ethintela ukugqithiswa kwamandla ngendlela ye-diode. Xa izibonda ezimbini ze-TVS ziphantsi kothuso oluguqukayo oludlulayo olunamandla amakhulu, inokuguqula i-impedance ephezulu phakathi kweepali ezimbini ibe yi-impedance ephantsi ngesantya se-10-12 imizuzwana, ifunxa ukuya kuthi ga kwii-kilowatts ezininzi zamandla otyando, kwaye ibambe intambo. amandla ombane phakathi kweepali ezimbini ngexabiso elimisiweyo, ekhusela ngokufanelekileyo amacandelo achanekileyo kwiisekethe zombane kumonakalo obangelwe kukubethwa ngumoya. Kuyilo lwemodyuli ye-SFP ebonakalayo,OLTizixhobo, Ethernettshintshakunye nezinye iimveliso zenethiwekhi, zihlala zisetyenziswa njengezixhobo ezikhuselayo zokukhusela iimveliso kunye nokufunxa umbane ongatshintshiyo.
Iimbonakalo:
(1) Isantya sokuphendula ngokukhawuleza (1ps);
(2) Amandla adlulayo aphezulu;
(3) Ukuvuza okuphantsi kombane;
(4) Ukutenxa kumbane omncinci wokucanda (5%);
(5) Isakhono esinamandla sokubamba, njl.njl;
(6) Isakhono esinamandla sokumelana nokunyuka kunye nokucinezela i-voltage.
Zisetyenziswa ngokubanzi kwiingqondiwena, imodyuli yonxibelelwano yamehlo, imodyuli yefiber ebonakalayo, imodyuli ye-sfp optical,oltizixhobo, Ethernettshintsha, inkqubo yekhompyutha, izixhobo zokunxibelelana, umbane we-AC / DC, i-automobile, i-ballast ye-elektroniki, izixhobo zasekhaya, izixhobo (i-watt hour meter), RS232/422/423/485, I/O, LAN, ISDN, ADSL, USB, MP3, I-PDAS, i-GPS, i-CDMA, i-GSM, ukukhuselwa kwekhamera yedijithali, imowudi eqhelekileyo / imowudi eyahlukileyo yokukhusela i-RF coupling / IC drive ifumana ukukhuselwa, ukunyanzeliswa kwe-motor electromagnetic interference, igalelo lomsindo / ividiyo, inzwa / ukuhanjiswa, isiphaluka solawulo lwemizi-mveliso, i-relay, i-contactor ingxolo yokucinezela, kunye neminye imimandla. Ngokodidi, lunokwahlulwa lube ngamanqaku amabini alandelayo:
(1) Ngokutsho kwepolarity, inokwahlulwa ibe ziindidi ezintathu: i-unipolar ne-bipolar;
(2) Ngokwenjongo: inokwahlulwa ibe zizixhobo ezisetyenziselwa iinjongo eziqhelekileyo ezifanelekileyo kwiisekethe ezahlukahlukeneyo kunye nezixhobo ezikhethekileyo ezifanelekileyo kwiisekethe ezikhethekileyo. Ngokomzekelo, izikhuseli ezahlukeneyo ze-AC voltage, i-4-20mA izikhuseli zangoku, izikhuseli zedatha yedatha, izikhuseli ze-cable coaxial, izikhuseli zefowuni, njl.
(3) Ngokuhambelana nokupakishwa kunye nesakhiwo sangaphakathi, sinokwahlulwa sibe yi-axial lead diode, i-TVS ye-inline arrays ezimbini (ezilungele ukukhuselwa kwemigca emininzi), uhlobo lwe-patch, uhlobo lwemodyuli, kunye nohlobo lwemodyuli yamandla aphezulu.
I-TVS inokudityaniswa ngokuhambelana nomgca kwaye ingasetyenziselwa ukunyanzeliswa kokunyuka ngokukhawuleza. Ngaphantsi kweemeko eziqhelekileyo zokusebenza, i-TVS ibonisa i-impedance state ephezulu kumacandelo akhuselweyo, angachaphazeli ukusebenza okuqhelekileyo komgca. Xa i-pulse overvoltage engaqhelekanga idlula i-voltage yayo yokuphuka, i-TVS iyatshintsha ukusuka kwi-impedance state ephezulu ukuya kwi-impedance ephantsi. Umzila we-impedance ophantsi unikezelwa ukuguqula ukuhamba kwangoku ngokukhawuleza kumacandelo akhuselweyo kwi-diode ye-TVS, kwaye i-surge yangoku ikhutshwe ngokukhawuleza kwi-tube ye-TVS, ngelixa inciphisa ngokuchanekileyo i-voltage kwinqanaba elikhuselekileyo, Xa ukugqithisa okungaqhelekanga kulahleka, i-TVS ngokukhawuleza ubuyela kwimeko ephezulu yokuxhathisa.
Oku ngasentla kushwankathelo olufutshane lweTVS Transient Voltage Suppression Diode Principle and Application Characteristics TVS Tube, enokusebenza njengereferensi kumntu wonke. Inkampani yethu ineqela lobugcisa elomeleleyo kwaye inokubonelela ngeenkonzo zobugcisa kubathengi. Okwangoku, inkampani yethu ineemveliso ezahlukeneyo: ezikrelekrelewena, imodyuli yonxibelelwano yamehlo, imodyuli yefiber ebonakalayo, imodyuli ye-sfp optical,oltizixhobo, Ethernettshintshakunye nezinye izixhobo zenethiwekhi. Ukuba ufuna, unokuba nokuqonda okunzulu.
