Ubudlelwane phakathi kokupakishwa kwe-MOSFET kunye neeparamitha, ungakhetha njani iiFET ngokupakishwa okufanelekileyo

①Iplagi yokupakisha: TO-3P, TO-247, TO-220, TO-220F, TO-251, TO-92;

② Uhlobo lokunyuka komphezulu: TO-263, TO-252, SOP-8, SOT-23, DFN5 * 6, DFN3 * 3;

Iifom zokupakisha ezahlukeneyo, umda ohambelanayo wangoku, i-voltage kunye nefuthe lokutshatyalaliswa kobushushuI-MOSFETiya kwahluka. Intshayelelo emfutshane yile ilandelayo.

1. TO-3P/247

I-TO247 yenye yeepakethe ezincinci ezisetyenziswa ngokuqhelekileyo kunye neepakethi zokunyuka komphezulu. I-247 yinombolo yesiriyali yomgangatho wephakheji.

Zombini iphakheji ye-TO-247 kunye ne-TO-3P iphakheji ine-3-pin output. Iichips ezingenanto ngaphakathi zinokufana ngokuthe ngqo, ngoko ke imisebenzi kunye nokusebenza ngokusisiseko kuyafana. Okona kuninzi, ukutshatyalaliswa kobushushu kunye nokuzinza kuchaphazeleka kancinci.

I-TO247 ngokuqhelekileyo iphakheji engafakwanga. I-TO-247 iityhubhu zisetyenziswa ngokubanzi kuMANDLA aphezulu. Ukuba isetyenziswe njengetyhubhu yokutshintsha, i-voltage yayo yokumelana kunye neyangoku iya kuba nkulu. Yifomu yokupakisha eqhele ukusetyenziswa kumbane ophakathi-phezulu kunye neeMOSFET zangoku. Imveliso ineempawu zokuxhathisa amandla ombane aphezulu kunye nokumelana nokuqhekeka okunamandla, kwaye ifanelekile ukuba isetyenziswe kwiindawo ezinombane ophakathi kunye nenkulu yangoku (ngoku ngaphezu kwe-10A, ixabiso lokumelana nombane ngaphantsi kwe-100V) ngaphezu kwe-120A, kunye nexabiso lokumelana nombane ngaphezu kwe-200V.

2. UKUYA-220/220F

Inkangeleko yezi ndlela zimbini zepakethe yeIi-MOSFETsiyafana kwaye inokusetyenziswa ngokutshintshanayo. Nangona kunjalo, i-TO-220 ine-sink yokushisa ngasemva, kwaye umphumo wayo wokutshatyalaliswa kobushushu ungcono kune-TO-220F, kwaye ixabiso libiza kakhulu. Ezi mveliso zimbini zepakethe zifanelekile kwizicelo kwi-medium-voltage kunye ne-high-current-current applications ngaphantsi kwe-120A kunye ne-high-voltage kunye ne-high-current applications ngaphantsi kwe-20A.

3. UKUYA-251

Le mveliso yokupakisha isetyenziselwa ukunciphisa iindleko kunye nokunciphisa ubungakanani bemveliso. Isetyenziswa kakhulu kwiindawo ezinevoltheji ephakathi kunye nephezulu yangoku engaphantsi kwe-60A kunye nombane ophezulu ongaphantsi kwe-7N.

4. UKUYA-92

Le phakheji isetyenziselwa kuphela i-low-voltage MOSFET (ikhoyo ngoku ingaphantsi kwe-10A, ukumelana nombane ongaphantsi kwe-60V) kunye ne-high-voltage 1N60/65, ngokukodwa ukunciphisa iindleko.

5. UKUYA-263

Kukwahluka kwe-TO-220. Ikakhulu yenzelwe ukuphucula ukusebenza kakuhle kwemveliso kunye nokutshatyalaliswa kobushushu. Ixhasa umbane ophezulu kakhulu wangoku kunye nombane. Ixhaphake kakhulu kwi-medium-voltage high-current MOSFETs ngaphantsi kwe-150A nangaphezulu kwe-30V.

6. UKUYA-252

Yenye yeepakethe eziqhelekileyo zangoku kwaye ifanelekile kwiindawo apho amandla ombane aphezulu angaphantsi kwe-7N kunye nombane ophakathi ungaphantsi kwe-70A.

7. SOP-8

Le phakheji ikwayilelwe ukunciphisa iindleko kwaye ixhaphake kakhulu kumbane ophakathi kwee-MOSFETs ngaphantsi kwe-50A kunye nombane ophantsi.Ii-MOSFETsmalunga ne-60V.

8. SOT-23

Ilungele ukusetyenziswa kwindawo enedijithi enye yangoku kunye ne-voltage ye-60V nangaphantsi. Ikwahlulwe ibe ziindidi ezimbini: umthamo omkhulu kunye nomthamo omncinci. Umahluko ophambili ulele kumaxabiso ahlukeneyo angoku.

Oku kungasentla yeyona ndlela ilula yokupakisha ye-MOSFET.
