A Schottky diode tseem hu ua tus cab kuj kub diode ; Nws yog semiconductor diode nrog rau kev ua haujlwm nrawm heev, tab sis qhov qis qis rau pem hauv ntej poob. Thaum ib tug flows los ntawm lub diode muaj ib tug me me voltage poob thoob plaws diode cov davhlau ya nyob twg.

Xav txog qhov no, qhov txawv ntawm Schottky diode thiab ib txwm diode yog dab tsi?

Raws li nyob rau hauv Schottky diode kev sib tshuam yog nyob rau hauv nruab nrab N hom semiconductor rau hlau phaj. Cov scottky thaiv diode muaj electrons raws li feem ntau muaj nyob rau ntawm ob sab ntawm txoj kev sib tshuam. Yog li nws yog ib qho khoom siv unipolar. Ib lo lus rau pem hauv ntej voltage poob (Vf) yog tsawg dua piv rau ib txwm PN kev sib tshuam hom diodes.

Ib yam li ntawd, lub diode ua haujlwm li cas? Lub luag haujlwm tseem ceeb. Feem ntau ua haujlwm ntawm a diode yog tso cai rau hluav taws xob tam sim no mus rau hauv ib qho kev taw qhia (hu ua cov diode rau pem hauv ntej), thaum thaiv nws nyob rau hauv qhov opposite direction (rov qab kev taw qhia). Assuch, ua diode tuaj yeem saib raws li hluav taws xob version ntawm acheck valve.

Tom qab, lo lus nug yog, dab tsi yog txhais los ntawm Schottky diode?

Cov Schottky diode (lub npe tom qab Germanphysicist Walter H. Schottky ), kuj hu ua Schottky thaiv diode los yog kub-carrier diode , yog asemiconductor diode tsim los ntawm kev sib tshuam ntawm cov asemiconductor nrog cov hlau. Nws muaj lub zog qis rau pem hauv ntej poob thiab avery ceev hloov ua haujlwm.

Dab tsi yog qhov zoo ntawm Schottky diode?

Ib qho ntawm thawj qhov zoo siv a Schottky diode dhau ib txwm diode yog lawv lowforward voltage poob. Qhov no tso cai rau ib Schottky diode toconsume tsawg voltage tshaj tus qauv diode , siv tsuas yog 0.3-0.4V hla nws cov junctions.
