Hukama huri pakati peMOSFET kurongedza uye paramita, maitiro ekusarudza maFET ane akakodzera kurongedza

①Plug-in kurongedza: TO-3P, TO-247, TO-220, TO-220F, TO-251, TO-92;

②Surface mount type: TO-263, TO-252, SOP-8, SOT-23, DFN5*6, DFN3*3;

Akasiyana mafomu ekurongedza, iyo inoenderana muganho ikozvino, voltage uye kupisa kupisa mhedzisiro yeMOSFETzvichava zvakasiyana. Sumo pfupi ndeiyi inotevera.

1. TO-3P/247

TO247 ndeimwe yeanonyanya kushandiswa madiki epakeji mapakeji uye pamusoro pegomo mapakeji. 247 ndiyo serial nhamba yepakeji standard.

Ose ari maviri TO-247 package uye TO-3P package ine 3-pini inobuda. Iwo machipisi asina chinhu mukati anogona kunyatsofanana, saka mabasa uye kuita kwakafanana. Kazhinji, kupisa kwekupisa uye kugadzikana kunokanganisa zvishoma.

TO247 kazhinji isiri-insulated package. TO-247 machubhu anowanzo shandiswa mune yakakwirira-simba SIMBA. Kana yakashandiswa sechubhu yekuchinja, inomira voltage uye ikozvino ichave yakakura. Iyo inowanzoshandiswa kurongedza fomu yepakati-yakakwirira voltage uye yakakwirira-ikozvino MOSFETs. Chigadzirwa chacho chine maitiro ekukwirira kwemagetsi uye kuparara kwakasimba, uye chakakodzera kushandiswa munzvimbo dzine mhepo yepakati uye yakakura ikozvino (ikozvino pamusoro pe10A, voltage resistance value pazasi 100V) pamusoro pe120A, uye voltage resistance value iri pamusoro pe200V.

2. TO-220/220F

Kuonekwa kweaya maviri mapakeji masitayipi eMOSFETszvakafanana uye zvinogona kushandiswa zvakasiyana. Zvisinei, TO-220 ine sink yekupisa kumusana, uye kupisa kwayo kupisa kwemhepo kuri nani pane iyo ye TO-220F, uye mutengo unodhura zvakanyanya. Zvigadzirwa zviviri izvi zvepasuru zvakakodzerwa kunyorera mukati-voltage uye yakakwirira-ikozvino zvikumbiro pazasi 120A uye yakakwirira-voltage uye yakakwirira-ikozvino zvikumbiro pazasi 20A.

3. TO-251

Ichi chigadzirwa chekurongedza chinonyanya kushandiswa kuderedza mutengo uye kuderedza chigadzirwa saizi. Inonyanya kushandiswa munzvimbo dzine mhepo yepakati uye yakakwira ikozvino pazasi 60A uye yakakwira voltage pazasi 7N.

4. TO-92

Iyi pasuru inongoshandiswa kune yakaderera-voltage MOSFET (ikozvino pazasi 10A, inomira voltage pazasi 60V) uye yakakwira-voltage 1N60/65, kunyanya kuderedza mutengo.

5. TO-263

Iyo mutsauko we TO-220. Inonyanya kugadzirirwa kuvandudza kushanda kwekugadzira uye kupisa kupisa. Inotsigira yakanyanya kukwira ikozvino uye voltage. Iyo inowanzojairika mune yepakati-voltage yakakwira-ikozvino MOSFETs pazasi 150A uye pamusoro pe30V.

6. TO-252

Ndiyo imwe yemapakeji emazuva ano uye inokodzera nharaunda uko high voltage iri pazasi 7N uye yepakati voltage iri pazasi 70A.

7. SOP-8

Iri pasuru rakagadzirirwawo kuderedza mutengo uye rinowanzo zivikanwa mukati mepakati voltage MOSFETs pazasi 50A uye yakaderera voltage.MOSFETskusvika 60V.

8. SOT-23

Inokodzera kushandiswa mune imwechete-digit ikozvino uye voltage nharaunda ye60V uye pazasi. Yakakamurwa kuva marudzi maviri: vhoriyamu hombe uye vhoriyamu diki. Musiyano mukuru uri muhunhu hwakasiyana hwazvino.

Iyo iri pamusoro ndiyo yakapusa MOSFET yekurongedza nzira.
