Qhov txiaj ntsig tseem ceeb ntawm SBD suav nrog ob yam:
1) Vim tias Schottky barrier qhov siab yog qis dua qhov siab ntawm PN junction barrier qhov siab, rau pem hauv ntej conduction pib voltage thiab pem hauv ntej voltage poob qis dua cov PN hlws ris diode (txog 0.2V qis).
2) Vim tias SBD yog ib yam ntawm cov khoom siv hluav taws xob feem ntau, tsis muaj cov neeg nqa khoom tsawg lub neej thiab cov teeb meem rov qab los. Lub sijhawm rov qab los ntawm SBD tsuas yog lub sijhawm them nqi thiab tawm ntawm Schottky barrier capacitor, uas txawv kiag li ntawm lub sijhawm rov qab los ntawm PN junction diode. Txij li thaum tus nqi rov qab los ntawm SBD yog qhov me me, qhov kev hloov pauv ceev ceev heev thiab qhov kev hloov pauv yog qhov tshwj xeeb me me, uas yog tshwj xeeb tshaj yog haum rau cov ntawv thov ntau zaus.
Txawm li cas los xij, qhov rov qab tawg hluav taws xob ntawm SBD yog qhov tsawg vim tias qhov cuam tshuam rov qab ntawm SBD yog nyias thiab tawg yooj yim tshwm sim ntawm nws qhov chaw. Txij li thaum SBD yooj yim dua los ua kom tawg los ntawm cua sov dua PN junction diode, qhov rov qab xau tam sim no loj dua li ntawm PN junction diode.
