Njengenye yemishini eyisisekelo kakhulu emkhakheni we-semiconductor, ama-MOSFET asetshenziswa kabanzi kukho kokubili ukwakheka kwe-IC namasekethe asezingeni lebhodi. Njengamanje, ikakhulukazi emkhakheni wama-semiconductors anamandla amakhulu, izinhlobonhlobo zezinhlaka ezihlukene zama-MOSFET nazo zidlala indima engenakuthathelwa indawo. NgobaAma-MOSFET, isakhiwo esingasho ukuthi siyisethi elula futhi eyinkimbinkimbi kwelinye, elula ilula ekwakhiweni kwayo, inkimbinkimbi isekelwe ekusetshenzisweni kokucatshangelwa kwayo okujulile. Ezinsukwini zansuku zonke,I-MOSFET ukushisa kubuye kubhekwe njengesimo esivame kakhulu, isihluthulelo esidinga ukwazi izizathu ezivela lapho, futhi yiziphi izindlela ezingaxazululwa? Okulandelayo masihlangane ukuze siqonde.
I. Izimbangela zeI-MOSFET ukushisa
1, inkinga yokuklama kwesifunda. Okokuvumela i-MOSFET ukuthi isebenze esimweni se-inthanethi, hhayi esimweni sokushintsha. Lesi ngesinye sezizathu ezenza i-MOSFET ishise. Uma i-N-MOS ishintsha, i-voltage yeleveli ye-G kufanele ibe ngama-V ambalwa ngaphezu kwamandla kagesi ukuze ikhanyise ngokugcwele, futhi okuphambene kuyiqiniso ku-P-MOS. Ayivuleki ngokuphelele futhi ukwehla kwe-voltage kukhulu kakhulu okuholela ekusetshenzisweni kwamandla, i-impedance ye-DC efanayo inkulu kakhulu, ukwehla kwe-voltage kuyanda, ngakho-ke u-U * nami ngiyakhuphuka, ukulahlekelwa kusho ukushisa.
2, imvamisa iphezulu kakhulu. Ikakhulukazi kwesinye isikhathi iba nkulu kakhulu kumthamo, okuholela ekwandeni kwemvamisa, ukulahleka kwe-MOSFET ekwenyukeni, okuholela nasekushisiseni kwe-MOSFET.
3, i-current iphezulu kakhulu. Uma i-ID ingaphansi komkhawulo wamanje, izophinda ibangele ukuthi i-MOSFET ishise.
4, ukukhetha kwemodeli ye-MOSFET akulungile. Ukumelana kwangaphakathi kwe-MOSFET akucatshangelwa ngokugcwele, okuholela ekwandeni kokuphazamiseka kokushintsha.二,
Isixazululo sokukhiqiza ukushisa okukhulu kwe-MOSFET
1, Yenza umsebenzi omuhle ekwakhiweni kukasinki wokushisa we-MOSFET.
2, Faka osinki abasizayo abanele.
3, Namathisela ingcina ye-sink yokushisa.
Isikhathi sokuthumela: May-19-2024
