Pehea e koho ai i ka pūʻolo MOSFET pono?

maʻamauMOSFETʻO nā pūʻolo:

① pūʻolo hoʻopili: TO-3P, TO-247, TO-220, TO-220F, TO-251, TO-92;

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

ʻOkoʻa nā ʻano pūʻolo like ʻole, MOSFET e pili ana i ka palena o kēia manawa, ka uila a me ka wela wela, e wehewehe pōkole ʻia ma lalo nei.

1、TO-3P/247

ʻO TO247 kekahi o nā puʻupuʻu liʻiliʻi liʻiliʻi i hoʻohana pinepine ʻia, ʻano puʻupuʻu mauna i luna, ʻo 247 ka helu serial o ka maʻamau o ka pūʻolo.

ʻO ka pūʻolo TO-247 a me ka pūʻolo TO-3P he 3-pin output, i loko o ka pahu pahu (ʻo ia hoʻi, ka diagram kaapuni) hiki ke ʻano like, no laila ua like ke ʻano o ka hana a me ka hana, ʻo ka hapa nui, hoʻopau ʻia ka wela a me ke kūpaʻa. !

ʻO TO247 ka mea maʻamau ʻaʻole insulated pūʻolo, TO-247 paipu ke hoʻohana maʻamau i ka mana kiʻekiʻe POWER, hoʻohana ʻia ma ke ʻano he paipu hoʻololi, ʻoi aku ka nui o kona kū ʻana i ka volta a me ke ʻano o kēia manawa. i ke ʻano o nā pūʻolo, ʻo ka huahana he kiʻekiʻe kūʻē i ka uila, kiʻekiʻe kūʻē i ka wāwahi, a me nā mea ʻē aʻe, kūpono no ka waena-voltage a me ka kiʻekiʻe o kēia manawa (i kēia manawa o 10A a ʻoi aku paha, kū i ka waiwai uila o 100V a i ʻole) i ka It He kūpono ia no ka uila uila a me ke kiʻekiʻe o kēia manawa (i kēia manawa ma luna o 10A, ke kumu kūʻai o ka uila ma lalo o 100V) a ma luna o 120A, ka waiwai kūʻai uila ma luna o 200V.

2、TO-220/220F

ʻO kēia mau ʻano pūʻolo ʻelua oMOSFETʻaneʻane like ka hiʻohiʻona, hiki ke hoʻohana ʻia, akā ʻoi aku ka wela o ke kua o ka TO-220, ʻoi aku ka maikaʻi o ka hopena wela ma mua o ka TO-220F, ʻoi aku ka nui o ke kumukūʻai. He kūpono kēia mau pūʻolo ʻelua no ka 120A a i ʻole ka liʻiliʻi, ka uila kiʻekiʻe kiʻekiʻe 20A a i ʻole ka liʻiliʻi.

3、TO-251

ʻO kēia puʻupuʻu ka mea nui e hōʻemi i nā kumukūʻai a hōʻemi i ka nui o ka huahana, hoʻohana nui ʻia i ka uila uila kiʻekiʻe 60A a i ʻole ka liʻiliʻi, kiʻekiʻe voltage 7N a i ʻole ka liʻiliʻi.

 

4、TO-92

ʻO ka pūʻolo haʻahaʻa haʻahaʻa MOSFET wale nō (i kēia manawa ma lalo o 10A, ka waiwai uila ma lalo o 60V) a me ka 1N60/65 kiʻekiʻe-voltage i ka hoʻohana ʻana, ʻoi loa e hoʻemi i nā kumukūʻai.

5、TO-263

He ʻano like ʻole ia o TO-220, i hoʻolālā nui ʻia e hoʻomaikaʻi i ka hana hana a me ka hoʻopau wela, e kākoʻo i ke kiʻekiʻe kiʻekiʻe o kēia manawa a me ka uila, ma ka 150A ma lalo, 30V ma luna o ka volta waena a me ka MOSFET kiʻekiʻe o kēia manawa.

6、TO-252

ʻO ia kekahi o nā puʻupuʻu koʻikoʻi, kūpono no ka uila kiʻekiʻe ma lalo o 7N, ka uila uila ma lalo o 70A kaiapuni.

7、SOP-8

Hoʻolālā ʻia ka pūʻolo e hōʻemi i nā kumukūʻai, ma lalo o 50A i ka volta waena, 60V a i ʻole i ka haʻahaʻa haʻahaʻa.MOSFETʻoi aku ka maʻamau.

8、SOT-23

He kūpono no kekahi mau A i kēia manawa, 60V a me ka ʻenehana uila e hiki mai ana, i māhele ʻia i ʻelua ʻano o ka leo nui a me ka liʻiliʻi liʻiliʻi, ʻo ka ʻokoʻa nui ka ʻokoʻa o ka waiwai o kēia manawa.
