Indlela yokukhetha iphakheji efanelekileyo ye-MOSFET?

EqhelekileyoI-MOSFETiipakethe zezi:

① iphakheji yokufaka iplagi: TO-3P, TO-247, TO-220, TO-220F, TO-251, TO-92;

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

Iifom zephakheji ezahlukeneyo, i-MOSFET ehambelana nomda wangoku, i-voltage kunye nokutshatyalaliswa kobushushu iya kwahluka, ichazwe ngokufutshane ngezantsi.

1, TO-3P/247

I-TO247 yenye yeepakethe ezixhaphakileyo ezisetyenziswa ngokuqhelekileyo, i-surface Mount package, i-247 yinombolo yothotho lomgangatho wepakethe.

Iphakheji ye-TO-247 kunye ne-TO-3P iphakheji yi-3-pin imveliso, ngaphakathi kwe-chip engenanto (okt, umzobo wesekethe) inokufana ncam, ngoko ke umsebenzi kunye nokusebenza kuyafana, ubukhulu becala, ukuchithwa kobushushu kunye nokuzinza kuchaphazeleke kancinane. !

I-TO247 ngokubanzi ayifakwanga i-insulated, ityhubhu ye-TO-247 isetyenziswa ngokubanzi kuMANDLA wamandla aphezulu, esetyenziswa njengetyhubhu yokutshintsha, amandla ayo okumelana nombane kunye nangoku iya kuba nkulu kancinci kancinci, i-MOSFET yangoku ephezulu esetyenziswa ngokuqhelekileyo. ngohlobo lweepakethi, imveliso ine-voltage ephezulu yokumelana, ukuchasana okuphezulu kokuphuka, njl., ifanelekile kwi-medium-voltage kunye ne-high-current (ngoku ye-10A okanye ngaphezulu, ukumelana nexabiso lombane le-100V okanye ngaphantsi) kwi Ifanelekile kumbane ophakathi kunye nophezulu lwangoku (olukhoyo ngaphezu kwe-10A, ixabiso lokumelana nombane ngaphantsi kwe-100V) nangaphezulu kwe-120A, ixabiso lokumelana nombane ngaphezu kwe-200V.

2, TO-220/220F

Ezi ndlela zimbini zokupakisha zeI-MOSFETinkangeleko iphantse ifane, inokusetyenziswa ngokutshintshanayo, kodwa ngasemva kwe-TO-220 ine-sink yokushisa, umphumo wokutshatyalaliswa kobushushu ungcono kune-TO-220F, ixabiso libiza kakhulu. Ezi phakheji zimbini zifanelekile kwi-medium-voltage high-current 120A okanye ngaphantsi, i-high-voltage high-current 20A okanye izicelo ezingaphantsi.

3, UKUYA-251

Le phakheji ikakhulu yeyokunciphisa iindleko kunye nokunciphisa ubungakanani bemveliso, isetyenziswa ikakhulu kumbane ophakathi okhoyo ngoku wama-60A okanye ngaphantsi, amandla ombane aphezulu angama-7N okanye ubume obungaphantsi.

4, UKUYA-92

Iphakheji kuphela i-low-voltage MOSFET (ikhoyo ngoku ingaphantsi kwe-10A, ixabiso le-voltage ngaphantsi kwe-60V) kunye ne-high-voltage 1N60 / 65 ekusebenziseni, ngokukodwa ukunciphisa iindleko.

5, TO-263

Ngaba iyantlukwano ye-TO-220, eyilelwe ngokukodwa ukuphucula ukusebenza kakuhle kwemveliso kunye nokutshatyalaliswa kobushushu, ukuxhasa umbane ophezulu kakhulu wangoku kunye nombane, kwi-150A engezantsi, i-30V ngaphezu kombane ophakathi kunye ne-MOSFET yangoku ephezulu ixhaphake kakhulu.

6, UKUYA-252

Yenye yeephakheji eziqhelekileyo, ezifanelekileyo kumbane ophezulu ongaphantsi kwe-7N, umbane ophakathi ongaphantsi kwe-70A.

7, SOP-8

Iphakheji ikwayilelwe ukunciphisa iindleko, ngokubanzi ngaphantsi kwe-50A kumbane ophakathi, i-60V okanye kunjalo kwi-low-voltage.Ii-MOSFETszixhaphake kakhulu.

8, SOT-23

Ifanelekile kwii-A ezininzi zangoku, i-60V kunye nemeko ye-voltage elandelayo, eyahlulahlulwe kwiindidi ezimbini zomthamo omkhulu kunye nomthamo omncinci, umahluko omkhulu kukuba ixabiso langoku lihlukile.
