Schottky diode mu maulendo apakompyuta

Pambuyo popangidwa ndi chipangizo choyamba cha semiconductor, asayansi ambiri apambana afufuzira za katundu wa pn. Monga momwe mwadzidziwira, ichi ndi diode wamba yomwe ingakhoze kuwonetsedwa mu magetsi onse. Pa nthawi yomwe adayambitsa, idali chinthu chomwe chinapanga kusintha kwakukulu ndikusintha malingaliro onse za tsogolo lamakono. Komanso, sankasamaliranso makina opangira makina awo. Panali chithunzi cha Zenner ndi Gunn. China chinapangidwa ndi Schottky diode, Chomwe chili ndi zinthu zosangalatsa. Kugwiritsiridwa ntchito kwake pa zamagetsi sikunali kokondweretsa monga "abale" otchuka. Zapadera za chigawo ichi zidagwiritsidwa ntchito kale m'makampani apamwamba kwambiri ndipo sizinagwiritsidwe ntchito kwambiri. Chokondweretsa kwambiri ndi chakuti posachedwapa Schottky diode yakhala ikugwiritsidwa ntchito monga chinthu chofunikira kwambiri muzipangizo zamagetsi. Zimagwira pafupifupi zipangizo zonse zamagetsi: makanema, matepi ojambula, makompyuta, makompyuta, ndi zina zotero.

Zapadera za chipangizochi zikuwonetseredwa muzitsikira zochepa pa pn kulumikizana. Sichiposa 1,4 Volts. Izi zikutanthauza kuti, pafupi kwambiri ndi gawo loyenera, lomwe limagwiritsidwa ntchito powerengera. Zoona, pamtunda wa zoposa 50 volts izi zimatayika. Koma ngakhale, Schottky diode yakhala ikugwiritsidwa ntchito kwambiri m'madera ndi oplifiers. Mphamvu ya maulendowa sanadutse 15 Volts DC, yomwe inagwiritsidwa ntchito mokwanira ndi katundu wa chipangizo ichi. Akhoza kuyima muzithunzithunzi zowonjezera ngati chinthu cholepheretsa kapena kuchita nawo ntchito ya olamulira.

Kuphatikiza pa katundu wofunika ngati momwe galimoto ikugwera pansi pn kulumikizana, Schottky diode ili ndi kamtunda kakang'ono. Izi zimamulola kugwira ntchito pa maulendo apamwamba. Zomwe zimakhala "zokongola" za chinthu ichi sichimasokoneza chizindikiro cha maulendo apamwamba. Ndicho chifukwa chake zinasinthidwa ndi magetsi, makina olankhulana ndi olamulira.

Koma kuwonjezera pa makhalidwe abwino, m'pofunika kuzindikira zolephera. Ma Schottky diode ali ofunika kwambiri ngakhale kwa nthawi yochepa yowonjezera mphamvu yowonongeka kuchokera ku mtengo wovomerezeka. Izi zimabweretsa kulephera kwa mfundo. Mosiyana ndi "silicon" ya "silicon," iyo siibwerera. Kuwonongeka kwa kutenthedwa kwa mpweya kumachititsa kuti pakhale mafunde othamanga, kapena kuti "kusintha" kwa chipangizo kukhala woyendetsa.

Kulephera koyamba kumadzetsa ntchito yosakhazikika ya chipangizo chonse cha magetsi. N'zovuta kupeza ndi kuthetsa. Ponena za kuwonongeka kwa kutentha kwa mafuta, mwachitsanzo, mu mphamvu ya pulsed, izi zidzateteza chitetezo chachifupi. Pambuyo pokhala chinthu cholakwika, magetsi adzagwira ntchito bwino.

Makampani a masiku ano amapanga mphamvu zamphamvu za Schottky. Zomwe zilipo panopa zipangizo zingathe kufika ku 1.2 kA. Zomwe zimagwiritsidwa ntchito pakali pano zikufika 120 A. Zida zoterezi zili ndi machitidwe ambiri omwe alipo komanso machitidwe abwino. Zimagwiritsidwa ntchito bwino m'nyumba zamagetsi komanso zamagetsi.
