Transistors sib txawv ntawm txhua tus hauv cov lej: qauv, siab tshaj plaws dissipated zog, qhib tam sim no thiab qhib qhov hluav taws xob, thiab lwm yam. Tsuas yog cov transistor uas raug xaiv yuav ua haujlwm ntev nyob rau hauv Circuit Court uas nws tau nruab.
Cov Lus Qhia
Kauj ruam 1
Lub thauj khoom ntawm cov transistor yog txuas ntawm lub zog tsheb npav thiab tus sau cov cuab yeej. Yog hais tias qhov hluav taws xob ntawm txoj kev tsheb nqaj hlau no yog qhov zoo, siv tus n-p-n transistor, thiab yog tias tsis zoo, siv lub piston p-n-p transistor. Nco ntsoov tias lub teeb liab tswj tuav mus rau lub hauv paus yuav tsum muaj tib lub polarity tib yam li kev muab cov voltage.
Kauj ruam 2
Yog hais tias tus transistor yuav khiav lag luam nyob hauv hom analog, halve qhov voltage voltage thiab muab ntau los ntawm ib nrab ntawm qhov siab thauj khoom tam sim no. Qhov no yuav yog lub hwj chim dissipated los ntawm lub cuab yeej nyob rau hauv cov xwm txheej tsis zoo tshaj plaws - thaum nws qhib raws nraim ib nrab hnub. Yog tias nws ua haujlwm hauv hom tseem ceeb, lub zog siab tshaj plaws los ntawm nws yuav tsawg dua. Txhawm rau kom paub, ntxiv cov hluav taws xob poob thoob cov transistor hauv lub xeev qhib tag nrho (feem ntau tsuas yog kaum tawm ntawm qhov hluav taws xob) los ntawm cov ntsuas cov nqi tam sim no. Raws li qhov siv hluav taws xob ntau tshaj plaws, txiav txim siab yog tias koj cov khoom siv yuav tsum ua kom sov.
Kauj ruam 3
Siv qhov siab tshaj plaws tam sim no kos los ntawm lub load raws li qhov siab tshaj plaws ntawm-lub xeev tam sim no, thiab lub zog hluav taws xob voltage raws li qhov siab tshaj tawm ntawm xeev-voltage. Cov kev txwv ntawm qhov transistor yuav tsum tshaj tus nqi nyob hauv Circuit Court, tsawg kawg ib zaug thiab ib nrab zaug.
Kauj ruam 4
Xaiv cov hloov hloov tam sim no nyob ntawm qhov sib piv ntawm cov tswj tam sim no thiab lub thauj tam sim no. Piv txwv li, yog tias qhov ntsuas no yog 50, ces lub thauj khoom tam sim no tuaj yeem dhau qhov kev tswj hwm tam sim no los ntawm tsawg kawg 50 zaug. Raws li qhov no, xaiv tus nqi ntawm cov resistor hauv puag ncig.
Kauj ruam 5
Yog hais tias tus load yog qhov inductive, txuas lub diode nyob rau hauv thaum uas tig mus nrog tus txheem polarity ntawm lub zog mov.
Kauj Ruam 6
Pom cov transistor hauv phau ntawv siv, txhua tus yam ntxwv uas dhau ntawm cov raug xaiv nrog qee cov npoo. Tsis txhob cia lub cuab yeej ua haujlwm ntawm ob lossis ntau qhov ntsuas huab tsis tseem ceeb. Muaj nruab lub transistor uas koj xaiv nyob rau hauv lub cuab yeej, cia nws ua hauj lwm rau ob peb teev, tom qab ntawd tua, tawm ntawm lub tshuab hluav taws xob hauv nws thiab ntsuas qhov ntsuas kub ntawm transistor. Nws yuav tsum tsis tshaj 50 degrees.
