Kwindawo yombane, iidiode zeZener zibambe isikhundla esikhethekileyo, esahlulwe ngokukwazi ukulawula amandla ombane kunye nokukhusela ukujikeleza okubuthathaka. Ngaphandle kokuqina kwazo, iidiode zeZener, njengalo naliphi na icandelo lombane, ngamanye amaxesha zinokuhlangabezana nemiba ethintela ukusebenza kwazo ngokufanelekileyo. Esi sikhokelo sibanzi sijonga kwihlabathi le-Zener diode yokulungisa iingxaki, ukuxhobisa abafundi ngolwazi kunye nobuchule bokufumanisa kunye nokusombulula iingxaki eziqhelekileyo.
Ukuchonga imiba yeDiode yeZener eqhelekileyo
Iidiode zeZener zinokubonakalisa imiba eyahlukeneyo echaphazela ukusebenza kwazo:
I-Diode evulekileyo: I-diode evulekile ibonisa ukuba akukho conductivity, okukhokelela kwisiphaluka esivulekileyo. Oku kunokubangelwa ngumonakalo womzimba okanye ukungaphumeleli kwecandelo langaphakathi.
I-Diode emfutshane: I-diode emfutshane isebenza njengefutshane ngokuthe ngqo, ivumela i-current ukuba ihambe ngokungalawulekiyo. Oku kunokubangelwa kukugqithiswa kombane okanye umonakalo womzimba.
I-Zener Breakdown Voltage (Vz) Umahluko: Ukuba i-voltage ye-Zener diode yokuqhawula i-voltage iyatenxa kwixabiso layo elichaziweyo, inokusilela ukulawula amandla ombane ngokufanelekileyo.
Ukugqithiswa kwamandla okugqithisileyo: Ukugqithisa umda wokutshatyalaliswa kwamandla e-Zener diode kunokubangela ukushisa kunye nomonakalo.
Isizukulwana Sengxolo: Iidiode zeZener zinokuzisa ingxolo kwisekethe, ngakumbi kwimisinga ephezulu.
Iindlela zokulungisa iingxaki zeZener Diode
Ukusombulula ngempumelelo imiba yeZener diode, landela la manyathelo acwangcisiweyo:
Ukuhlolwa okubonakalayo: Qalisa ngokujonga ngokubonakalayo i-Zener diode nayiphi na imiqondiso yomonakalo womzimba, njengokuqhekeka, ukuguquka kombala, okanye amanqaku okutshisa.
Ukukhangela okuqhubekayo: Sebenzisa i-multimeter ukwenza ukukhangela okuqhubekayo. I-diode evulekileyo ayiyi kubonisa ukuqhubeka, ngelixa i-diode emfutshane iya kubonisa ukuchasana kufuphi ne-zero.
Umlinganiselo wombane: Yenza umlinganiselo wombane ngapha kwe diode ye Zener kuzo zombini iimeko eziya phambili nezingasemva. Thelekisa amaxabiso alinganisiweyo kumbane wokuqhekeka ochaziweyo.
Ukubalwa kokutshatyalaliswa kwamandla: Bala ukuchithwa kwamandla usebenzisa ifomyula: Amandla = (I-Voltage × yangoku). Qinisekisa ukuba ukuchithwa kwamandla kuhlala ngaphakathi kwemida yediode.
Uhlalutyo Lwengxolo: Ukuba ingxolo iyakrokrelwa, sebenzisa i-oscilloscope ukujonga umqondiso wemveliso yesekethe. Chonga nayiphi na ingxolo okanye ukuguquguquka okuvela kwingingqi yeZener diode.
Amanyathelo okuthintela kwiMiba yeZener Diode
Ukunciphisa imiba ye-Zener diode, qwalasela la manyathelo okuthintela:
Ukhetho oluLungileyo: Khetha iidiode zeZener ezinevoltheji efanelekileyo kunye nemilinganiselo yangoku yosetyenziso.
Usetyenziso lweSinki yoBubushushu: Sebenzisa iisinki zobushushu ukuba idiode yeZener isebenza kufutshane nomda wokuchitha amandla.
Ukukhuselwa kweSekethe: Sebenzisa izixhobo zokukhusela, ezifana ne-fuses okanye i-surge arrestors, ukukhusela i-Zener diode kwiziganeko zokugqithisa.
Ubuchwephesha bokuNciphisa ingxolo: Qwalasela ubuchule bokunciphisa ingxolo, njenge-capacitor yokudibanisa okanye iisekethe zokucoca, ukunciphisa ukuveliswa kwengxolo.
Ukuqukumbela
Iidiode zeZener, ezineempawu zazo ezixabisekileyo, zisebenza njengamacandelo ayimfuneko kwiisekethe ze-elektroniki. Nangona kunjalo, ukuqonda kunye nokujongana nemiba enokubakho kubalulekile ekuqinisekiseni ukusebenza kwabo ngeyona ndlela iphezulu. Ngokulandela iindlela zokusombulula iingxaki kunye nemilinganiselo yokukhusela echazwe kwesi sikhokelo, abafundi banokufumanisa ngokufanelekileyo kwaye basombulule iingxaki ze-Zener diode, ukugcina ukuzinza nokuthembeka koyilo lwabo lwe-elektroniki.
