Cov yam ntxwv ntawm Silicon Carbide Schottky Barrier Diode (SBD)

Cov yam ntxwv ntawm Silicon Carbide Schottky Barrier Diode (SBD)

SiC SBDs (Schottky barrier diodes) nrog lub zog tawg ntawm 600V (ntau tshaj qhov txwv sab sauv ntawm silicon SBDs) thiab saum toj no tau yooj yim tau. Piv nrog silicon FRD (ceev rov qab diode), SiC SBD muaj ntau qhov rov qab rov qab tam sim no thiab lub sijhawm rov qab los, yog li txo qis rov qab poob thiab suab nrov. Tsis tas li ntawd, tsis zoo li silicon FRDs, cov yam ntxwv no tsis hloov pauv tseem ceeb hauv qhov ntsuas kub tam sim no thiab kev ua haujlwm. SiC SBD tso cai rau cov neeg tsim qauv los txhim kho kev ua haujlwm zoo, txo tus nqi thiab qhov loj ntawm cov dab dej kub, nce kev hloov zaus kom txo qhov loj thiab tus nqi ntawm cov khoom sib nqus, thiab lwm yam.

SiC-SBD tau siv ntau ntxiv hauv cov khoom siv hluav taws xob hloov hluav taws xob (PFCs) thiab cov txuas txuas txuas txuas ntxiv hauv kev hloov cov khoom siv hluav taws xob. Cov ntawv thov niaj hnub no suav nrog cua txias, hnub ci cua txias, hluav taws xob tsheb chargers, khoom siv hauv tsev, thiab lwm yam.

ROHM tam sim no SiC SBD lineup suav nrog 600V thiab 1200V; Qhov ntsuas tam sim no yog 5A txog 40A. Lub 1700V ntaus ntawv tab tom tsim.

Cov txiaj ntsig ntawm SiC hauv semiconductors

Raws li kev lag luam rau cov khoom siv hluav taws xob thiab cov logic boards txuas ntxiv mus, cov kev tsis txaus ntawm cov tsoos silicon tau dhau los ua qhov tseem ceeb. Yog li ntawd, cov neeg tsim qauv thiab cov chaw tsim khoom tau tshawb nrhiav txoj hauv kev zoo dua thiab ntse dua los tsim cov khoom tseem ceeb no. Silicon carbide yog qhov zoo li no. Vim nws qhov loj bandgap dav thiab zoo heev thermal conductivity, piv rau cov tsoos silicon technology, silicon carbide technology yuav muab ob qho tib si yam ntxwv tseem ceeb ntawm high zaus thiab siab. Ntxiv mus, silicon carbide chips ntawm tib lub specifications tsuas yog ib feem kaum ntawm silicon chips. Tsis tas li ntawd, nyob rau hauv daim ntawv thov raws li cov cuab yeej siv silicon carbide, tsawg dua cov cua kub dissipation thiab cov khoom siv me me ua rau muaj kev txo qis hauv tag nrho qhov loj ntawm lub cuab yeej.

Yog li ntawd, silicon carbide fais fab semiconductors sawv tawm ntawm cov zoo tib yam silicon semiconductors thiab muaj dav daim ntawv thov kev cia siab nyob rau hauv teb xws li hluav taws xob fais fab, optoelectronics, thiab microwave kev sib txuas lus.
