1 • rau pem hauv ntej cov yam ntxwv
Nyob rau hauv hluav taws xob circuits, lub anode ntawm lub diode ntawm lub kub kawg, tsis zoo nyob rau hauv cov uas tsis muaj kawg, lub diode yuav ua no kev twb kev txuas, lub npe hu ua lub rau pem hauv ntej kev tsis ncaj ncees. Yuav tsum hais, thaum lub diode rau pem hauv ntej qhov hluav taws xob muaj tsawg heev, diode tseem tuaj yeem hla tsis dhau, rau pem hauv ntej tam sim no ntws los ntawm diode muaj zog heev. Tsuas yog thaum lub pa hluav taws xob tau nce mus txog qee qhov tseem ceeb (tus nqi no hu ua" tus ntsuas hluav taws xob" GE raj yog kwv yees li 0.2V, Silicon yog li 0.6V), diode conduction. Breakover diode voltages nyob twj ywm tseem ceeb tsis hloov (GE raj yog kwv yees li 0.3V, silicon raj muaj kwv yees li 0.7V), hu ua diode" siab poob" ;.
2 • rov qab tus xeeb ceem
Hauv hluav taws xob xaim hluav taws xob, qhov tsis zoo ntawm diode ntawm qhov txias kawg, qhov tsis zoo ntawm qhov kub kawg, tam sim no me me hauv diode, thiab diode hauv lub xeev ib yam li lub sijhawm no, daim ntawv txuas no, paub tias thim rov qab kev tsis ncaj ncees. Thaum lub diode yog rov qab ntxub, muaj yuav tseem yuav muaj ib tug tsis muaj zog rov qab tam sim no ntws los ntawm lub diode, lub npe hu ua to tam sim no. Thaum lub diode rov qab qhov hluav taws xob tau nce mus rau qee yam muaj nuj nqis, rov qab tam sim no nce ntau, cov diode yuav poob qhov kev coj ua ib qho kev coj ua, lub xeev no hu ua kev cuam tshuam ntawm diode Txhaj tam sim no yuav tsum tau ntau dua qhov tseem ceeb heev tam sim no ceev ntawm lub laser diode, laser mus rov qab tej yam kev mob uas tau ntsib thiab muab. Mob siab rau tam sim no ntom ntom thiab qhov kub thiab txias, thiab tsis ncaj qha rau cov txiaj ntsig. Kev ua haujlwm kub siab, qhov tseem ceeb tshaj tawm tam sim no, muaj txiaj ntsig thiab txo qis lossis txawm ua rau cov khoom tsis zoo.
