Kuongororwa kweParameter uye kuyerwa kweMOSFETs

Kune akawanda marudzi makuru ma parameters eMOSFET, iyo ine DC yazvino, AC yazvino paramita uye miganhu paramita, asi iyo yakajairika application inongoda kuve nehanya neanotevera maparamita: saturation mamiriro eiyo leakage sosi ikozvino IDSS pinch-off voltage Kumusoro, transconductance gm, leakage source breakdown voltage BUDS, iyo yakakura kurasikirwa inoburitsa simba PDSM uye yakakura leakage sosi yazvino IDSM.

1.Saturated leakage source current

Iyo saturated drain-source yazvino IDSS inoreva iyo drain-source ikozvino pagedhi voltage UGS = 0 mujunction kana depletion rudzi insulated-layer gedhi MOSFETs.

2. Clip-off voltage

Iyo pinch-off voltage UP zvinoreva gedhi remagetsi rinoshanda pajunction kana depletion type insulated layer gedhi.MOSFETizvo zvinoita kuti drain-source ingogurwa. Ona kuti IDSS neUP zvinorevei chaizvo.

3, Batidza voltage

Iyo yekutendeuka-on voltage UT inoreva gedhi remagetsi rinoshanda magetsi mune yakasimbiswa insulated-gedhi MOSFET kuitira kuti iyo drain-source yekubatanidza ingobatidzwa. Ona kuti UT inorevei chaizvo.

4.Cross-guidance

Iyo transguide gm inoshandiswa kuratidza kugona kwegedhi sosi voltage kudzora kudonhedza ikozvino, ndiko kuti, chiyero pakati pekuchinja kweiyo drain ikozvino uye shanduko yegedhi source voltage.

5, Yakanyanya kurasikirwa yekubuda simbar

Yakanyanya kurasikirwa inoburitsa simba zvakare ndeyeyemuganho paramende, zvinoreva iyo yakanyanya kudonha-sosi kurasikirwa simba iro rinogona kubvumidzwa kana kuita kweiyo.MOSFETzvakajairika uye hazvibatike. Kana isu tikashandisa MOSFET, kurasikirwa kwayo kwekushanda kunofanira kunge kwakaderera pane PDSM uye imwe kukosha.

6、Maximum leakage source ikozvino

Iyo yakanyanya drain-source ikozvino, IDSM, zvakare inodzikamisa parameter, zvinoreva iyo yakanyanya ikozvino inotenderwa kupfuura pakati pekudonhedza uye kunobva MOSFET panguva yekushanda kwakajairika, uye haifanirwe kudarika kana MOSFET iri kushanda.

olukey yave imwe yeakanakisa uye inokurumidza kukura vamiririri muAsia kuburikidza neanoshanda musika kusimudzira uye inobudirira kubatanidza zviwanikwa, uye kuve mumiriri akakosha kwazvo munyika ndicho chinangwa chakajairwa che olukey.
