Lub nruab hnub ci lub thawv ua haujlwm ua ke nrog cov khoom sib txuas, nruab hnub ci lub thawv uas yuav tsum muaj kev yoog kom haum rau ib puag ncig. Hauv kev hais txog qhov kub thiab txias, tus qauv tam sim no yog -40 ℃ ~ 85 ℃. Qhov kev sib tshuam kub ntawm lub diode yuav cuam tshuam rau qhov tam sim no to hauv nws lub xeev. Feem ntau hais lus, hnub ci hlws ris lub thawv txeej tam sim no yuav ob npaug rau txhua kaum qib ntawm qhov kub nce. Yog li no, hnub ci hlaws ris lub thawv nws yog qhov tsim nyog rau lub diode' s rated hlws ris kub tshaj yuav tsum siab dua qhov tseeb hlws ris kub tshaj thaum siv. Piv txwv li, 2AP1 hom germanium diode, lub hnub ci lub thawv yog qhov thim rov qab tam sim no yog 250uA ntawm 25, qhov kub siab yuav nce mus txog 35, qhov hloov hluav taws xob tam sim no yuav nce mus rau 500uA, thiab lwm yam, lub hnub ci lub thawv ntawm 75, nws qhov hluav taws xob rov qab tau mus txog 8mA, lub hnub ci kev sib txuas lub thawv tsis tsuas yog ploj Txoj kev ua haujlwm tsis tuaj yeem yuav ua rau cov kab hlau ua kom sov thiab ua rau nws puas.
Qhov ntsuas kub qhov tseeb tiag tiag tuaj yeem ntsuas los ntawm cov hauv qab no: muab cov khoom sib xyaw rau hauv 75 degree qhov cub kom txog thaum nws sov sov, lub hnub ci lub thawv hla dhau qhov luv luv-tam sim no ntawm cov feem hauv cov diode, lub hnub ci lub thawv thiab ntsuas qhov saum npoo. qhov kub ntawm lub diode tom qab thermal stability (piv txwv li, 1h), raws li cov qauv hauv qab no Xam xyuas qhov tseeb qhov ntsuas kub: Tj=Tcase + R * U * I, lub hnub ci lub thawv uas R yog lub thermal tiv qhov co, muab los ntawm lub chaw tsim khoom diode, Tcase yog qhov kub saum npoo ntawm diode (ntsuas nrog lub ntsuas cua), lub hnub ci lub thawv thiab U yog qhov ntsuas hluav taws xob hla ntawm diode (ntsuas ntsuas tus nqi), Kuv yog cov khoom tiv thaiv luv-Circuit Court tam sim no. Lub xam Tj tsis tuaj yeem siab tshaj qhov ntsuas kub ntawm qhov ntsuas ntawm cov diode cov ntaub ntawv siv.
Cov txheej txheem los ntsuas seb qhov kev sib tshuam ntawm qhov kub ntawm lub diode puas tsim nyog lossis tsis yog raws li hauv qab no: cov khoom tivthaiv tag nrho yog ua kom sov li 75 ° C, lub hnub ci hlws ris lub thawv thiab tom qab thim rov qab tam sim no ntawm Isc tau thov rau 1h, hnub ci hlws ris lub thawv qhov kub ntawm txoj kev hla dej ntawm kev ntsuas yuav tsum qis dua qhov siab tshaj qhov ua haujlwm kub. Tom qab ntawd nce cov khoom nkag rov qab tam sim no rau 1.25 zaug Isc rau 1h, hnub ci hlaus ris lub thawv thiab cov bypass diode yuav tsum tsis txhob poob.
