Cov ntaub ntawv tseem ceeb ntawm Diodes

Lub diode yog ib qho khoom siv hluav taws xob ua los ntawm cov khoom siv hluav taws xob (silicon, selenium, germanium, thiab lwm yam). Nws muaj unidirectional conductivity, uas yog, thaum ib tug pem hauv ntej voltage yog siv rau lub anode ntawm lub diode, lub diode yog qhib. Thaum qhov hluav taws xob rov qab siv rau lub anode thiab cathode, lub diode raug tua. Yog li ntawd, nyob rau hauv thiab tawm ntawm lub diode yog sib npaug rau lub on thiab tawm ntawm lub switch.

Diode yog ib qho ntawm cov khoom siv semiconductor thaum ntxov, thiab nws daim ntawv thov yog dav heev. Tshwj xeeb tshaj yog nyob rau hauv ntau yam hluav taws xob circuits, diodes thiab resistors, capacitors, inductors thiab lwm yam khoom yog siv rau tsim nyog kev twb kev txuas los tsim circuits nrog txawv zog, uas yuav paub rectification ntawm alternating tam sim no, nrhiav kom tau ntawm modulated signals, amplitude limiting thiab clamping, thiab fais fab mov. Kev tswj hluav taws xob thiab lwm yam haujlwm. Cov kab diode tuaj yeem pom nyob rau hauv cov xov tooj cua sib xws nrog rau hauv lwm cov khoom siv hauv tsev lossis kev tswj xyuas kev lag luam.
