schottky diodes

Schottky diode, tseem hu ua barrier diode, yog ib hom hluav taws xob tivthaiv uas tau siv dav hauv ntau yam khoom siv hluav taws xob. Nws yog lub npe hu ua Walter H. Schottky, uas nrhiav tau qhov tshwm sim nyob rau hauv cov hlau-semiconductor junctions nyob ib ncig ntawm 1938. Schottky diodes muaj ib tug tshwj xeeb cov cuab yeej uas ua rau lawv muab ceev hloov ceev, tsis tshua muaj voltage poob thiab high efficiency.

Lub ntsiab feature ntawm ib tug Schottky diode yog hais tias nws muaj ib tug tsawg pem hauv ntej voltage poob. Qhov no txhais tau hais tias nws tuaj yeem ua haujlwm tam sim no tau zoo dua li tus qauv diode, uas yog ib qho tseem ceeb hauv kev siv ntau zaus. Tsis tas li ntawd, Schottky diodes muaj lub sij hawm rov qab sai heev, ua rau lawv zoo tagnrho rau siv hauv rectifiers thiab lwm yam khoom siv hluav taws xob.

Schottky diode siv cov hlau-semiconductor hlws ris los tsim lub zog thaiv ntawm cov hlau thiab cov khoom siv semiconductor. Qhov kev thaiv no tiv thaiv kev ntws ntawm cov hluav taws xob los ntawm cov hlau mus rau cov khoom siv semiconductor, tso cai rau lub diode ua ib txoj hauv kev rau hluav taws xob tam sim no. Thaum qhov hluav taws xob tau siv thoob plaws lub diode, cov khoom siv hluav taws xob tau yooj yim los ntawm cov khoom siv hluav taws xob mus rau cov hlau, tab sis tsis nyob rau hauv qhov sib txawv.

Schottky diodes feem ntau yog siv rau hauv lub zog hloov hluav taws xob, tshwj xeeb hauv cov khoom siv hluav taws xob hloov pauv (SMPS) thiab DC-rau-DC converters. Lawv kuj tau siv nyob rau hauv high-speed logic circuits, voltage clamp thiab surge tiv thaiv pab kiag li lawm, thiab voltage multipliers.

Hauv kev xaus, Schottky diode yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no. Nws qhov qis qis rau pem hauv ntej poob qis thiab lub sijhawm rov qab sai sai tau ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob ntau. Nrog nws cov kev ua haujlwm siab thiab kev hloov pauv ceev, Schottky diode tseem yog ib feem tseem ceeb ntawm cov cuab yeej siv niaj hnub no.
