Ho na le mefuta e mengata ea li-parameter tse kholoMOSFET, e nang le DC ea hajoale, li-parameter tsa hajoale tsa AC le meeli ea moeli, empa ts'ebeliso e akaretsang e hloka feela ho tsotella lintlha tse latelang tsa mantlha: boemo ba ho lutla ha mohloli oa hona joale oa IDSS pinch-off voltage Up, transconductance gm, leakage source breakdown voltage BUDS, matla a maholo a tahlehelo ea PDSM le mohloli o moholo oa ho lutla IDSM ea hajoale.
1.Saturated leakage source ea hona joale
IDSS ea hajoale ea mohloli oa drainage e bolela matla a metsi a tsoang hekeng ea UGS = 0 e mateanong kapa mofuta oa ho fokotseha ha liheke tsa MOSFET.
2. Clip-off voltage
Pinch-off voltage UP e bolela motlakase o sebetsang oa heke e mateanong a mateano kapa mofuta oa depletion e insulated layer gate.MOSFETseo se etsa hore drain-source e khaotsoe feela. Fumana hore na IDSS le UP li bolela'ng.
3. Bulela voltage
Motlakase oa ho bulela UT o bolela motlakase o sebetsang oa heke ho MOSFET e matlafalitsoeng e le hore khokahanyo ea mohloli oa drainage e sa tsoa buloa. Fumana hore na UT e bolela eng.
4.Tsela-tataiso
Transguide gm e sebelisetsoa ho bontša bokhoni ba motlakase oa mohloli oa heke ho laola motlakase oa metsi, ke hore, karo-karolelano pakeng tsa phetoho ea motlakase oa metsi le phetoho ea motlakase oa mohloli oa heke.
5, tahlehelo e kholo ea matla a tlhahisor
Boholo ba tahlehelo ea matla le eona ke ea paramethara ea moeli, e bolelang matla a mangata a tahlehelo ea mohloli o ka lumelloang ha ts'ebetso e etsoa.MOSFETe tloaelehile ebile ha e amehe. Ha re sebelisa MOSFET, tahlehelo ea eona ea ts'ebetso e lokela ho ba tlase ho feta PDSM le boleng bo itseng.
6、Maximum leakage source ea hona joale
IDSM, e leng palo e phahameng ka ho fetesisa ea mohlodi wa drainage, le yona ke paramethara e lekanyeditsweng, ho bolelang hore boholo ba jwale bo dumelletsweng ho feta pakeng tsa moedi le mohlodi wa MOSFET nakong ya tshebetso e tlwaelehileng, mme ha ya lokela ho fetiswa ha MOSFET e sebetsa.
olukey e se e le e 'ngoe ea li-agents tse ntseng li hola ka potlako Asia ka nts'etsopele ea 'maraka e sebetsang le kopanyo e sebetsang ea lisebelisoa,' me ho ba moemeli oa bohlokoa ka ho fetisisa lefatšeng ke sepheo se tloaelehileng sa olukey.
