Momwe mungasankhire phukusi loyenera la MOSFET?

WambaMOSFETphukusi ndi:

① Phukusi la pulagi: TO-3P, TO-247, TO-220, TO-220F, TO-251, TO-92;

② pamwamba phiri: TO-263, TO-252, SOP-8, SOT-23, DFN5 * 6, DFN3 * 3;

Mitundu yosiyanasiyana yamaphukusi, MOSFET yofanana ndi malire apano, kutayika kwamagetsi ndi kutentha kudzakhala kosiyana, kufotokozedwa mwachidule pansipa.

1, TO-3P/247

TO247 ndi imodzi mwamaphukusi ang'onoang'ono omwe amagwiritsidwa ntchito kwambiri, mtundu wa phukusi lapamwamba, 247 ndiye nambala ya seriyo ya phukusi.

Phukusi la TO-247 ndi phukusi la TO-3P ndizotulutsa 3-pini, mkati mwa chip chopanda kanthu (ie, chithunzi chozungulira) chikhoza kukhala chimodzimodzi, kotero ntchito ndi ntchito ndizofanana, makamaka, kutaya kutentha ndi kukhazikika kumakhudzidwa pang'ono. !

TO247 nthawi zambiri imakhala yopanda insulated phukusi, TO-247 chubu nthawi zambiri imagwiritsidwa ntchito mu MPHAMVU yamphamvu kwambiri, yomwe imagwiritsidwa ntchito ngati chubu chosinthira, mphamvu yake yoyimilira komanso yapano idzakhala yayikulu pang'ono yamagetsi apamwamba kwambiri, MOSFET omwe amagwiritsidwa ntchito nthawi zambiri. mu mawonekedwe a phukusi, mankhwala ali mkulu kupirira voteji, mkulu kukana kuwonongeka, etc., ndi oyenera sing'anga-voteji ndi mkulu-pano (panopa 10A kapena kuposa, kupirira voteji mtengo wa 100V kapena zochepa) mu Iwo. ndi oyenera sing'anga voteji ndi mkulu panopa (panopa pamwamba 10A, voteji kukana mtengo pansi 100V) ndi pamwamba 120A, voteji kukana mtengo pamwamba 200V.

2, TO-220/220F

Izi ziwiri phukusi masitaelo aMOSFETmaonekedwe ali pafupifupi ofanana, angagwiritsidwe ntchito mosiyana, koma kumbuyo kwa TO-220 kuli ndi kutentha kwa kutentha, kutentha kwa kutentha kumakhala bwino kuposa TO-220F, mtengo wake ndi wokwera mtengo kwambiri. Maphukusi awiriwa ndi oyenera sing'anga-voltage mkulu-current 120A kapena zochepa, high-voltage mkulu-panopa 20A kapena zochepa ntchito.

3, TO-251

Phukusili makamaka kuchepetsa ndalama ndi kuchepetsa mankhwala kukula, makamaka ntchito sing'anga voteji mkulu panopa 60A kapena zochepa, mkulu voteji 7N kapena zochepa chilengedwe.

 

4, KWA-92

Phukusili ndi MOSFET yotsika kwambiri (yomwe ili pansi pa 10A, mtengo wamagetsi pansi pa 60V) ndi 1N60/65 yapamwamba kwambiri pakugwiritsa ntchito, makamaka kuchepetsa ndalama.

5, TO-263

Ndi mtundu wa TO-220, womwe umapangidwa makamaka kuti upititse patsogolo kupanga bwino komanso kutayika kwa kutentha, kuthandizira kwambiri pakalipano komanso magetsi, mu 150A pansipa, 30V pamwamba pamagetsi apakatikati ndi MOSFET yaposachedwa ndiyofala kwambiri.

6, TO-252

Ndi imodzi mwamaphukusi ambiri, oyenera voteji yapamwamba pansipa 7N, sing'anga voteji pansipa 70A chilengedwe.

7, SOP-8

Phukusili lapangidwanso kuti lichepetse ndalama, nthawi zambiri pansi pa 50A mumagetsi apakatikati, 60V kapena kupitilira apo mumagetsi otsika.Zithunzi za MOSFETndizofala kwambiri.

8, SOT-23

Oyenera angapo A panopa, 60V ndi zotsatirazi voteji chilengedwe, amene amagawidwa mu mitundu iwiri ya voliyumu lalikulu ndi voliyumu yaing'ono, kusiyana kwakukulu ndi kuti mtengo panopa ndi osiyana.
