Lesi sihloko sihlola isimiso sokusebenza sama-TVS diode kanye nobubanzi bawo bezinhlelo zokusebenza emikhakheni efana nokuvikelwa kwe-overvoltage, ukuvikelwa kwe-ESD, nokuvikelwa kombani, okuveza inani lawo elibalulekile njengezingxenye eziyinhloko zokuvikela isifunda.

I-TVS iwavikela kanjani amasekhethi emiphumeleni yesikhashana yokudlula amandla?

Ukusebenza Isimiso: I-TVS diode isebenzisa isici sokuqhekeka kwe-avalanche ye-pn junction ngaphansi kokuchema okuhlanekezelwe. Lapho i-voltage idlula i-voltage yokuwohloka ye-TVS diode, ingena kusimo sokuqhuba bese iphambukisa yamanje emgqeni ophansi. Lesi senzo siqinisa i-overvoltage yesikhashana ibe sezingeni eliphephile, ivikela izingxenye ze-elekthronikhi ezibucayi. Ngamafuphi, i-TVS diode ingabamba ukugcwala ngokweqile kwesikhashana ibe sezingeni eliphephile phakathi nesikhathi esifushane kakhulu, inikeze ukuvikeleka okusebenzayo kwamasekhethi kagesi. Ukusabela kwayo okusheshayo nekhono eliphezulu lokumunca amandla kuyenza ibe inketho ekahle yokuvikela ugesi omningi.

Ngaphandle kokuvikela ugesi omningi, yiziphi ezinye izinto ezisetshenziswayo ama-TVS diode anazo? Ingabe zingasetshenziswa njengezingxenye zokucindezela iziphazamiso kumasekethe okucindezela umsindo?

Ama-TVS (Transient Voltage Suppressor) ama-diode anezinye izinhlelo zokusebenza ezimbalwa ngaphandle kokuvikela i-overvoltage futhi angasetshenziswa ngempela njengezingxenye zokucindezela iziphazamiso kumasekhethi okucindezela umsindo. Nazi izinhlelo zokusebenza ezimbalwa eziyinhloko nemisebenzi yama-TVS diode:

I-Anti-Electrostatic Discharge (ESD): Ama-diode e-TVS angakwazi ukumunca ngempumelelo ama-pulse wesikhashana ane-voltage ephezulu abangelwa ukukhishwa kwe-electrostatic, avikele izingxenye ze-elekthronikhi ezibucayi emonakalweni. Lokhu kubenza basetshenziswe kabanzi kumakhompiyutha, izinto zokuxhumana, izinto zikagesi zabathengi, nakweminye imikhakha.

Isivikelo Sombani: Ngamandla nemigqa yesignali, ama-diode e-TVS angasetshenziswa ukuvimbela ukuguquguquka kwesikhashana okubangelwa ukushaywa kombani, ukuvikela okokusebenza emonakalweni. Lokhu kubaluleke kakhulu kumishini yangaphandle kanye neziteshi eziyisisekelo zokuxhumana.
