Ubale pakati pa ma CD a MOSFET ndi magawo, momwe mungasankhire ma FET okhala ndi ma CD oyenera

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

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

Osiyana ma CD mitundu, malire lolingana panopa, voteji ndi kutentha dissipation zotsatira zaMOSFETzidzakhala zosiyana. Mau oyamba achidule ali motere.

1. TO-3P/247

TO247 ndi imodzi mwamaphukusi ang'onoang'ono omwe amagwiritsidwa ntchito kwambiri komanso mapaketi okwera pamwamba. 247 ndiye nambala ya seriyo ya muyezo wa phukusi.

Phukusi la TO-247 ndi TO-3P lili ndi zotulutsa 3-pini. Ziphuphu zopanda kanthu mkati zimatha kukhala chimodzimodzi, kotero ntchito ndi magwiridwe antchito ndizofanana. Nthawi zambiri, kutentha kwa kutentha ndi kukhazikika kumakhudzidwa pang'ono.

TO247 nthawi zambiri ndi phukusi lopanda insulated. Machubu a TO-247 nthawi zambiri amagwiritsidwa ntchito mu MPHAMVU yamphamvu kwambiri. Ngati atagwiritsidwa ntchito ngati chubu chosinthira, mphamvu yake yopirira komanso yapano idzakhala yayikulu. Ndi mawonekedwe omwe amagwiritsidwa ntchito kwambiri pamagetsi apakatikati komanso ma MOSFET apamwamba kwambiri. The mankhwala ali ndi makhalidwe a mkulu voteji kukana ndi amphamvu kuwonongeka kukana, ndi oyenera ntchito m'malo ndi sing'anga voteji ndi lalikulu panopa (panopa pamwamba 10A, voteji kukana mtengo m'munsimu 100V) pamwamba 120A, ndi voteji kukana mtengo pamwamba 200V.

2. KUTI-220/220F

Maonekedwe a mitundu iwiri ya phukusi laZithunzi za MOSFETndizofanana ndipo zimatha kugwiritsidwa ntchito mosiyanasiyana. Komabe, TO-220 ili ndi choyatsira kutentha kumbuyo, ndipo zotsatira zake zowonongeka zimakhala zabwino kuposa za TO-220F, ndipo mtengo wake ndi wokwera mtengo kwambiri. Awiri phukusi mankhwala ndi oyenera ntchito sing'anga-voteji ndi mkulu-panopa ntchito pansipa 120A ndi mkulu-voteji ndi mkulu-panopa ntchito pansi 20A.

3. KWA-251

Choyikachochi chimagwiritsidwa ntchito makamaka kuchepetsa ndalama komanso kuchepetsa kukula kwa mankhwala. Amagwiritsidwa ntchito makamaka m'madera omwe ali ndi magetsi apakati komanso apamwamba omwe ali pansi pa 60A ndi magetsi apamwamba pansi pa 7N.

4. KWA-92

Phukusili limangogwiritsidwa ntchito pa low-voltage MOSFET (panopa pansi pa 10A, kupirira voteji pansi pa 60V) ndi high-voltage 1N60/65, makamaka kuchepetsa ndalama.

5. KWA-263

Ndi mtundu wa TO-220. Amapangidwa makamaka kuti apititse patsogolo kupanga bwino komanso kutaya kutentha. Imathandizira kwambiri zamakono komanso magetsi. Ndizofala kwambiri mu ma MOSFET apakati-voltage apamwamba-panopa pansi pa 150A ndi pamwamba pa 30V.

6. KWA-252

Ndi imodzi mwazinthu zamakono zamakono ndipo ndi yoyenera kumalo omwe magetsi apamwamba ali pansi pa 7N ndipo voteji yapakati ili pansi pa 70A.

7. SOP-8

Phukusili lapangidwanso kuti lichepetse ndalama ndipo nthawi zambiri limakhala lodziwika kwambiri pamagetsi apakatikati a MOSFETs pansi pa 50A ndi magetsi otsika.Zithunzi za MOSFETpafupifupi 60v.

8. SOT-23

Ndi yoyenera kugwiritsidwa ntchito m'malo amtundu umodzi wamakono ndi ma voltage a 60V ndi pansi. Amagawidwa m'mitundu iwiri: voliyumu yayikulu ndi voliyumu yaying'ono. Kusiyana kwakukulu kuli muzinthu zosiyanasiyana zamakono.

Zomwe zili pamwambazi ndi njira yosavuta yopangira MOSFET.
