Cov qauv ntawm Diode

Lub diode yog encapsulated los ntawm ib tug PN hlws ris ntxiv rau cov coj electrode lead thiab raj plhaub.

Siv cov txheej txheem doping sib txawv, P-hom semiconductor thiab N-hom semiconductor yog tsim los ntawm tib lub semiconductor (feem ntau silicon lossis germanium) substrate los ntawm diffusion, thiab thaj chaw them nqi yog tsim los ntawm lawv qhov kev sib tshuam hu ua PN kev sib tshuam.

Cov electrode rub los ntawm thaj av P yog hu ua anode, thiab cov electrode rub los ntawm N cheeb tsam hu ua cathode. Vim hais tias ntawm unidirectional conductivity ntawm PN hlws ris, thaum lub diode qhib, tam sim no kev taw qhia yog los ntawm anode mus rau cathode los ntawm sab hauv ntawm lub raj.

Lub cim Circuit Court ntawm lub diode yog pom nyob rau hauv daim duab 1. Lub diode muaj ob lub electrodes, lub electrode tau kos los ntawm P cheeb tsam yog qhov zoo electrode, kuj hu ua anode; cov electrode rub los ntawm N cheeb tsam yog qhov tsis zoo electrode, kuj hu ua cathode. Cov kev taw qhia ntawm daim duab peb sab xub qhia txog cov kev taw qhia ntawm lub hauv ntej tam sim no, thiab cov ntawv cim ntawm lub diode yog sawv cev los ntawm VD.
