Kev soj ntsuam ntawm qhov qub Darlington

Sab hauv ntawm ib tug pa Darlington raj yog tsim los ntawm ib tug collector ntawm ob los yog ntau tshaj transistors txuas ua ke, thiab ib tug ntau ntawm emitter junctions muaj nyob nruab nrab ntawm lub hauv paus b thiab lub emitter e. Lub multimeter tuaj yeem ntsuas tau siv R x 1 kΩ lossis R × 10 kΩ cov ntaub ntawv ntawm multimeter.

Ntsuas qhov zoo thiab qhov tsis zoo kuj tseem ceeb ntawm cov electrodes ntawm Darlington raj. Nquag, tus nqi tiv thaiv rau pem hauv ntej ntawm lub collector c thiab lub hauv paus b (thaum NPN raj ntsuas, lub ntsuas dub txuas nrog lub hauv paus b; thaum ntsuas PNP raj, lub ntsuas dub txuas nrog c) thiab cov khoom siv silicon transistor yog hluav taws xob txuas nrog. Tus nqi tiv thaiv rau pem hauv ntej zoo sib xws, xws li 3 mus rau 10 kΩ, thiab tus nqi rov qab tsis muaj qhov kawg. Kev tiv thaiv pem hauv ntej ntawm lub emitter e thiab lub hauv paus b (lub meter dub txuas nrog lub hauv paus b thaum ntsuas lub NPN raj; lub ntsuas dub txuas nrog lub emitter e thaum ntsuas PNP raj) yog nruab nrab ntawm cov khoom siv c thiab cov puag b Tus nqi tiv thaiv pem hauv ntej yog 2 mus rau 3 zaug, thiab tus nqi rov qab ua haujlwm tsis kawg. Qhov tseem ceeb rau pem hauv ntej thiab thim rov qab kuj tseem ceeb ntawm tus sau c thiab emitter e yuav tsum nyob ze rau qhov tsis muaj tseeb. Yog tias qhov txiaj ntsig zoo thiab qhov tsis zoo ntawm qhov c thiab e ncej ntawm lub raj Darlington lossis qhov zoo thiab qhov tsis zoo ntawm cov ncej b thiab e, b thiab c ncej yog ze rau 0, lub raj tau tawg lawm. kev puas tsuaj. Yog hais tias qhov zoo thiab qhov tsis zoo kuj tseem ceeb ntawm b thiab e ncej ntawm Darlington raj raug ntsuas kom tsis kawg, lub raj yog qhib Circuit Court puas.
