Qhov zoo ntawm Schottky diode

SBD muaj qhov zoo ntawm kev hloov pauv ntau zaus thiab qis rau pem hauv ntej, tab sis nws qhov rov qab tawg qhov hluav taws xob yog qhov qis, feem ntau tsis siab tshaj 60V, thiab qhov siab tshaj plaws tsuas yog txog 100V, uas txwv nws cov ntawv thov ntau yam. Piv txwv li, lub freewheeling diode ntawm lub hwj chim switching ntaus ntawv nyob rau hauv switching fais fab mov (SMPS) thiab lub hwj chim yam kho (PFC) Circuit Court, high-frequency rectifier diode ntawm ntau tshaj 100V rau transformer theem nrab, 600V-1.2kV high-speed diode nyob rau hauv RCD tsis Circuit Court, thiab 600V diode rau PFC boost, tsuas yog ceev rov qab epitaxial diode (FRED) thiab ultra-ceev rov qab diode (UFRD) yog siv. Lub sijhawm rov qab los ntawm Trr ntawm UFRD kuj yog ntau tshaj 20ns, uas tsis tuaj yeem ua tau raws li qhov xav tau ntawm 1MHz mus rau 3MHz SMPS hauv thaj chaw xws li chaw nres tsheb. Txawm hais tias SMPS nrog lub zog hloov ntawm 100kHz, vim qhov loj conduction poob thiab hloov pauv ntawm UFRD, lub plhaub siab kub thiab qhov xav tau rau lub tshuab hluav taws xob loj, qhov ntim thiab qhov hnyav ntawm SMPS tau nce, uas tsis nyob rau hauv txoj kab nrog txoj kev loj hlob. trend of miniaturization thiab thinness. Yog li ntawd, txoj kev loj hlob ntawm high voltage SBD saum toj no 100V yeej ib txwm yog cov ntsiab lus ntawm kev tshawb fawb thiab kev tsom xam. Nyob rau hauv xyoo tas los no, SBD tau ua tiav kev vam meej, 150V thiab 200V high-voltage SBDs tau teev tseg, thiab ntau dua 1kV SBDs ua los ntawm cov ntaub ntawv tshiab kuj tau tsim ua tiav, yog li txhaj tshuaj tshiab thiab tseem ceeb rau hauv nws daim ntawv thov.
