Disadvantages ntawm Schottky diode

Qhov loj tshaj qhov tsis zoo ntawm Schottky diodes yog qhov rov qab tsis zoo ntawm qhov hluav taws xob tsawg thiab qhov rov qab xau tam sim no loj dhau. Piv txwv li, Schottky diodes ua los ntawm silicon thiab hlau muaj qhov siab tshaj qhov rov qab tsis zoo ntawm qhov ntsuas hluav taws xob tsuas yog 50V, thiab qhov rov qab xau tam sim no yog qhov zoo ntawm qhov kub thiab txias, uas yooj yim kom nrawm nrog qhov kub thiab txias. Hauv kev tsim qauv, kev saib xyuas yuav tsum tau them rau qhov teeb meem zais ntawm thermal runaway. Txhawm rau zam cov teeb meem saum toj no, qhov rov qab tsis zoo ntawm qhov hluav taws xob ntawm Schottky diodes hauv kev siv tiag tiag yuav tsawg dua li nws cov nqi ntsuas. Txawm li cas los xij, thev naus laus zis ntawm Schottky diodes kuj tau txhim kho, thiab cov nqi ntsuas ntawm qhov rov qab tsis zoo voltage tuaj yeem ncav cuag 200V.
