Qhov voltage uas a Zener diode tawg nyob rau hauv lub rov qab bias mob hu ua Zener Qhov hluav taws xob. Qhov tseeb, nws yog qhov voltage uas a Zener diode yog ua haujlwm. Muaj kev lag luam Zener diode muaj Zener hluav taws xob kev ntaus nqi los ntawm 3 volts mus rau 200 volts. Tus nqi ntawm kev puas tsuaj los yog Zener voltage nyob ntawm doping.
Raws li, Zener kuj yog dab tsi?
Cov tsis kam , RZ, ib zener diode yog tus nqi ntawm impedance hla lub diode uas ua zoo li me me tsis kam nyob rau hauv series nrog lub zener . Qhov no txhais tau hais tias qhov voltage hla ib zener diode tsis nyob twj ywm zoo kawg nkaus li cov zener tam sim no txawv.
Ib sab saum toj no, dab tsi yog nominal zener voltage? Zener diodes sib txawv nyob rau hauv specifications xws li npe ua haujlwm hluav taws xob , lub zog dissipation, siab tshaj plaws rov qab tam sim no, thiab ntim. Qhov hluav taws xob Vz: ua Zener voltage hais txog qhov rov qab tawg hluav taws xob -2.4V txog li 200V; tuaj yeem nce mus txog 1 kV thaum qhov siab tshaj plaws rau cov khoom siv saum npoo av (SMD) yog li 47 V).
Ib yam li ntawd, tib neeg nug, koj txhais li cas los ntawm Zener tawg?
Cov Zener kev puas tsuaj tuaj yeem txhais tau tias yog qhov ntws ntawm electrons hla p yam khoom thaiv ntawm valence band mus rau qhov sib npaug ntawm n-hom khoom conduction band.
Yuav ua li cas zener diodes poob?
Zener diode regulator Circuit Court, Zener voltage = 12.6V). Interestingly txaus, thaum twg Zener diodes poob vim lub zog dissipation ntau dhau, lawv feem ntau poob luv es tsis qhib. A diode ua tsis tiav Nyob rau hauv no txoj kev yog nkag tau yooj yim: nws poob yuav luag xoom voltage thaum biased ob txoj kev, zoo li ib daim hlau.

Dab tsi yog qhov ntsuas ntsuas?
Kev nkag siab yog lub khoos phis tawj me me tab sis muaj zog hauv koj lub vaj huam sib luag hluav taws xob los ntawm tus kws tshaj lij hluav taws xob uas muaj ntawv tso cai, feem ntau hauv tsawg dua 30 feeb. Siv ob lub clamp-on sensors thiab 240V breaker, theSense saib cov qauv tam sim no thiab qhov hluav taws xob ib lab zaus ib thib ob los txiav txim seb koj lub zog mus qhov twg
Leej twg ua qhov ntsuas ntsuas ntsuas?
UNIT TESTING yog ib theem ntawm kev sim software uas ib tus neeg/cov khoom ntawm cov software raug kuaj. Lub hom phiaj yog los xyuas kom meej tias txhua chav ntawm lub software ua tau raws li tsim. Ib chav tsev yog qhov tsawg tshaj plaws kuaj tau ib feem ntawm ib qho software
Dab tsi yog qhov ntsuas qhov ntsuas ntau?
Ib txwm nyiam hom kev tshawb fawb tsim uas tau cuam tshuam cov txiaj ntsig-raws li kev ntsuas kev ntsuas yog kev ntsuas ntau. Kev ntsuam xyuas ntau muaj ntau yam ntawm cov cuab yeej sau cov ntaub ntawv suav nrog kev xam phaj, cov lus nug, thiab kev xeem
Dab tsi yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas thib ob?
Primary index: nyob rau hauv ib tug sequentially order file, qhov Performance index uas nws search key qhia cov sequential order ntawm cov ntaub ntawv. Kuj hu ua clustering index. Secondary index: ib qho Performance index uas nws qhov tseem ceeb tshawb nrhiav qhia qhov kev txiav txim sib txawv ntawm qhov kev txiav txim ntawm cov ntaub ntawv. Kuj hu ua non-clustering index
Dab tsi yog qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas?
Xav txog nws li no: rhiab heev yog ib qho kev ntsuas ntawm qhov hloov pauv ntawm lub koob yees duab qhov chaw saib uas tsim nyog raws li qhov muaj peev xwm tshawb pom, thiab qhov pib yog qhov ntau npaum li cas ntawm cov lus tsa suab yuav tsum tshwm sim txhawm rau txhawm rau ua rau lub tswb
