Schottky diode yog Schottky diode, tseem hu ua Schottky barrier diode (SBD), uas yog lub zog qis, ultra-high-speed semiconductor ntaus ntawv. Qhov tseem ceeb tshaj plaws yog tias lub sij hawm rov qab rov qab yog luv heev (raws li me me li ob peb nanoseconds), thiab rau pem hauv ntej ntawm voltage poob tsuas yog hais txog 0.4V. Nws yog tsuas yog siv raws li high-frequency, low-voltage, loj tam sim no rectifier diode, free wheeling diode, tiv thaiv diode, thiab kuj siv raws li rectifier diode thiab me me teeb liab nrhiav diode nyob rau hauv microwave kev sib txuas lus thiab lwm yam circuits. Nws yog ib txwm muaj nyob rau hauv kev sib txuas lus fais fab mov thiab zaus converter.
Ib daim ntawv thov raug yog hais tias nyob rau hauv lub switching Circuit Court ntawm lub bipolar transistor BJT, lub Shockley diode yog txuas nrog rau BJT kom clamp, yog li ntawd lub transistor yog tiag tiag nyob rau hauv ib tug heev ze ntawm lub xeev nyob rau hauv lub xeev, yog li txhim kho lub switching ceev ntawm lub transistor. transistor. Txoj kev no yog cov txheej txheem siv hauv TTL sab hauv circuits ntawm cov digital ICs xws li 74LS, 74als, thiab 74As.
Cov yam ntxwv loj tshaj plaws ntawm Schottky diode yog tias qhov hluav taws xob rau pem hauv ntej poob VF yog qhov me me. Nyob rau hauv tib lub tam sim no, nws cov pem hauv ntej voltage poob yog tsawg dua. Tsis tas li ntawd, nws lub sijhawm rov qab los yog luv luv. Nws kuj muaj qee qhov tsis zoo: qhov kev tiv thaiv hluav taws xob yog qhov tsawg, thiab cov xau tam sim no loj dua me ntsis. Kev txiav txim siab dav dav yuav tsum tau ua thaum xaiv.
