Nka kimwe mu bikoresho byibanze mu gice cya semiconductor, MOSFET ikoreshwa cyane mubishushanyo mbonera bya IC hamwe nubuyobozi bwurwego rwumuzunguruko. None se ni bangahe uzi kubyerekeye ibipimo bitandukanye bya MOSFET? Ninzobere muri orta na voltage MOSFETs,Olukeyazagusobanurira muburyo burambuye ibipimo bitandukanye bya MOSFETs!
VDSS ntarengwa yamazi-isoko ihangane na voltage
Umuyoboro-w-isoko-yumuvuduko iyo umuyoboro wamazi utemba ugeze ku gaciro kihariye (kuzamuka cyane) munsi yubushyuhe bwihariye hamwe n-isoko-ngufi. Umuyoboro wamazi wamazi muriki kibazo nanone witwa avalanche breakdown voltage. VDSS ifite coefficient nziza yubushyuhe. Kuri -50 ° C, VDSS igera kuri 90% yibyo kuri 25 ° C. Bitewe namafaranga asigara mubikorwa bisanzwe, impanuka ya avalanche yamashanyarazi yaBYINSHIni burigihe iruta nominal yagenwe voltage.
Urwibutso rushyushye rwa Olukey: Kugirango hamenyekane ibicuruzwa byizewe, mubihe bibi byakazi, birasabwa ko imbaraga zumurimo zitagomba kurenga 80 ~ 90% byagaciro kagenwe.
VGSS ntarengwa irembo-isoko ihangane na voltage
Yerekeza ku gaciro ka VGS mugihe impinduka zinyuranye hagati y irembo nisoko zitangiye kwiyongera cyane. Kurenza iyi voltage agaciro bizatera dielectric gusenyuka kumuryango wa oxyde oxyde, gusenya kandi bidasubirwaho.
Indangamuntu ntarengwa yamashanyarazi-isoko
Yerekeza kumurongo ntarengwa wemerewe kunyura hagati yumuyoboro nisoko iyo transistor yumurima ikora mubisanzwe. Imikorere ikora ya MOSFET ntigomba kurenza ID. Iyi parameter izagabanuka uko ubushyuhe bwihuriro bwiyongera.
IDM ntarengwa pulse yamashanyarazi-isoko
Yerekana urwego rwimikorere ya pulse igikoresho gishobora gukora. Iyi parameter izagabanuka uko ubushyuhe bwihuriro bwiyongera. Niba iyi parameter ari nto cyane, sisitemu irashobora kuba ifite ibyago byo gusenywa nubu mugihe cya OCP.
PD imbaraga nyinshi
Yerekeza kumurongo ntarengwa wamazi-isoko yamashanyarazi yemerewe atabangamiye imikorere yumurima wa transistor. Iyo ikoreshejwe, imbaraga nyazo zikoreshwa mumashanyarazi ya transistor igomba kuba munsi ya PDSM hanyuma igasiga intera runaka. Ibi bintu mubisanzwe bigenda byiyongera uko ubushyuhe bwihuza bwiyongera.
TJ, ubushyuhe bwimikorere ya TSTG hamwe nububiko bwibidukikije
Ibipimo byombi bihinduranya ubushyuhe bwubushyuhe bwemewe nigikoresho gikora nububiko. Ubu bushyuhe bwashyizweho kugirango bwuzuze byibuze ubuzima bukenewe bwibikoresho. Niba igikoresho cyemewe gukora muri ubu bushyuhe, ubuzima bwakazi buzongerwa cyane.
