Photodiodes yog siv rau hauv cov khoom siv hluav taws xob siv hluav taws xobxws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv kho mob thiab cov khoom siv rau cov chaw taws teeb tswj infrared siv los tswj cov khoom siv los ntawm TV mus rau cov cua txias.. Rau ntau daim ntawv thov xws li photodiodes lossis photoconductors yuav raug siv.
Dab tsi yog qhov tseem ceeb ntawm photodiode?
Photodiodes yog siv rau hauv cim paub circuits Photodiodes yog siv rau kev ntsuas tseeb ntawm kev siv lub teeb hauv kev tshawb fawb thiab kev lag luam. Photodiodes sai dua thiab nyuaj dua li ib txwm PN hlws ris diode thiab yog li nquag siv rau kev tswj teeb pom kev zoo thiab kev sib txuas lus kho qhov muag.
Cov ntawv thov twg tuaj yeem siv phototransistors thiab photodiodes?
Cov ntawv thov tseem ceeb ntawm photodiodes yog nyob rau hauv hnub ci cell, lub teeb sensor, thiab lwm yam. Cov ntawv thov tseem ceeb ntawm Phototransistors yog IR receiver circuit, LASER detector, Counter, etc.
Yuav ua li cas lub photodiode ua haujlwm?
Photodiode ua haujlwm hauv reverse bias condition Rov qab voltages yog plotted raws X axis hauv volts thiab rov qab tam sim no yog plotted raws Y-axis hauv microampere. Rov qab tam sim no tsis nyob ntawm qhov rov qab voltage. Thaum tsis muaj lub teeb illumination, rov qab tam sim no yuav luag xoom.
Photodiodes qhia nws siv thiab muab nws lub cim dab tsi?
Lub cim ntawm photodiode zoo ib yam li ib txwm p-n hlws ris diode tshwj tsis yog tias nws muaj cov xub tawm tsam lub diode. Cov xub ntaus lub diode sawv cev lub teeb lossis photons. Lub photodiode muaj ob lub davhlau ya nyob twg: lub cathode thiab anode.
