A Zener diode yog silicon semiconductor ntaus ntawv uas tso cai rau tam sim no ntws nyob rau hauv ib tug rau pem hauv ntej los yog rov qab kev taw qhia. Cov Zener diode muaj ib tug zoo-txhais rov qab-txuag voltage, nyob rau hauv uas nws pib ua tam sim no, thiab ua hauj lwm tsis tu ncua nyob rau hauv lub rov qab-bias hom yam tsis tau puas.
Ib yam li ntawd, zener diode ua haujlwm li cas?
Zener diodes yog dav siv raws li voltage references thiab raws li shunt regulators los tswj cov voltage nyob rau hauv me me circuits. Thaum sib txuas ua ke nrog qhov sib txawv ntawm qhov voltage kom nws rov qab biased, a Zener diode ua thaum lub voltage nce mus txog qhov cov diode rov qab breakdown voltage.
Kuj Paub, Zener diode zoo li cas? Cov Zener diode coj tus cwj pwm xwb nyiam ib txwm general-purpose diode muaj ib tug silicon PN hlws ris thiab thaum biased nyob rau hauv lub tom ntej kev taw qhia, uas yog Anode zoo nrog rau nws cov Cathode, nws coj xwb. nyiam ib txwm teeb liab diode dhau qhov ntsuas tam sim no.
Raws li txoj cai, Zener diode yog dab tsi?
Cov zener diode yog a diode tsim los ua haujlwm hauv cheeb tsam tawg thiab muaj qhov tshwj xeeb tsis zoo voltage hu ua zener hluav taws xob. Nyob rau hauv qhov voltage, lub diode yuav mus rau hauv kev puas tsuaj. Qhov no yog ib yam mob uas tso cai rau tam sim no ntws thaum tuav ib tug tas li voltage nyob rau hauv lub diode.
Dab tsi yog qhov txawv ntawm diodes?
Muaj ntau hom diodes muaj rau siv nyob rau hauv electronics tsim, uas yog; ib thaub qab diode , BARITT diode , Gunn Diode , Laser diode , Lub teeb emitting diodes , Photodiode, PIN diode , PN Junction, Schottky diodes , kauj ruam rov qab diode , Qhov diode , Varactor diode thiab Zener diode.

Dab tsi yog cov ntaub ntawv yooj yim tsim los ua thiab nws ua tiav cov haujlwm no li cas?
Lub hom phiaj tseem ceeb tshaj plaws ntawm cov ntaub ntawv kaw lus yog tswj cov neeg siv cov ntaub ntawv. Qhov no suav nrog khaws cia, rov qab thiab kho cov ntaub ntawv. Qee lub tshuab ua ntaub ntawv lees txais cov ntaub ntawv khaws cia raws li cov kwj ntawm bytes uas tau sau thiab khaws cia kom zoo rau kev tshaj tawm
Daim ntawv teev kev sib pauv yog dab tsi thiab nws txoj haujlwm yog dab tsi?
Daim ntawv teev kev lag luam yog cov ntaub ntawv sib txuas ntawm txhua qhov kev hloov pauv hauv cov ntaub ntawv thaum cov ntaub ntawv tiag tiag muaj nyob rau hauv cov ntaub ntawv sib cais. Daim ntawv teev kev lag luam muaj cov ntaub ntawv txaus los tshem tawm tag nrho cov kev hloov pauv tau ua rau cov ntaub ntawv cov ntaub ntawv ua ib feem ntawm ib qho kev sib pauv
Tus neeg tua neeg OOM yog dab tsi thaum nws khiav thiab nws ua dab tsi?
OOM Killer ua haujlwm los ntawm kev tshuaj xyuas tag nrho cov txheej txheem khiav thiab muab lawv cov qhab nia phem. Cov txheej txheem uas tau qhab nia siab tshaj yog tus uas raug tua. OOM Killer muab cov qhab nia ua phem raws li ntau yam
Kev tshawb xyuas network yog dab tsi thiab nws ua li cas thiab vim li cas nws thiaj xav tau?
Network auditing yog txheej txheem uas koj lub network tau teeb tsa ob qho tib si ntawm software thiab kho vajtse. Cov txheej txheem tuaj yeem ua rau poob siab yog tias ua tiav manually, tab sis hmoov zoo qee cov cuab yeej tuaj yeem pab automate ib feem ntawm cov txheej txheem. Tus thawj coj yuav tsum paub tias lub tshuab thiab cov cuab yeej txuas nrog lub network li cas
Dab tsi yog Zener diode muab nws lub cim?
Lub cim ntawm zener diode yog qhia hauv daim duab hauv qab no. Zener diode muaj ob lub ntsiab lus: cathode thiab anode. Hauv zener diode, hluav taws xob tam sim no ntws los ntawm ob qho tib si anode mus rau cathode thiab cathode rau anode. Lub cim ntawm zener diode zoo ib yam li p-n hlws ris diode, tab sis nrog khoov npoo ntawm lub ntsug bar
