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.
