Tohu transistors - he aha te mea te reira? Types, tawhā me ngā āhuatanga o transistors, tohu

mahi te transistor rite te wähanga matua o tetahi circuitry. Ko ia he ahua o whakapakari kī. Ko te pūtake o tenei pūrere Semiconductor ko te takawai germanium ranei karaihe. He unipolar me pourua nga transistors me, runga i, mara, me te pourua. kitea ratou e rua ngā momo o te momo kawe ia - whakamua me whakamuri. No te tīmata, reo irirangi amateur te raruraru matua, ko te aronga o te whakawaehere me wetemuna o enei āhuatanga. I roto i tēnei tuhinga ka titiro tatou ki nga momo matua o ngā pūkete, me te tātari e rua hua kāinga me te ke, e te tikanga transistors tohu.

momo o te tuhi

Manufacturers transistors whakamahi rua ngā momo matua o te whakamunatanga - he waehere tae me te tapanga. Heoi, e kore te kotahi e kore te atu e kore e whai paerewa ōrite. Ia otaota hoki e hua pūrere Semiconductor (transistors, te p, p zener, a na i runga i. D.), faaohipa i tona waehere me te tae waehere. Ka taea e Te whakatau transistors o tetahi rōpū me te momo hua e tipu rerekē, me te e tapaina ratou rerekē. Ranei hurihia: he rerekē nga mea timatanga, a ka tirohia ki a ratou - ōrite. I roto i ngā take pēnei, ki te wehewehe i waenganui i a ratou anake i runga i te āhuatanga atu. Hei tauira, te roa o te ritenga atu kitenga tae kaituku, me te tango rānei (ranei mua) mata. Tohu FETs he kahore rerekē i te tūtohu i ētahi atu pūrere. Ko ki ngā āhuatanga Semiconductor o te take mai ke te taua āhuatanga: whakamahia ia kaiwhakanao ratou iku'anga momo.

Transistors i KT-26 casing

A feruri e te transistors tohu hua motu. Ko tino rongonui i roto i ngā kaiwhakanao Semiconductor tenei momo o te whare. He he hanga porotakaroa ki te taha bevelled, e toru whakatau puta i te turanga o raro. I roto i tenei take, faaohipahia te reira i te parau tumu o te whakauru tohu me te kei ngā tohu waehere, me te tae. I runga i te turanga o runga he tae-ira, te tikanga rōpū transistor, me te taha ki te topetope - waehere tohu tae ranei ira e ōrite ana ki te momo pūrere. I tua atu ki te momo, e taea te tono ki te tau me te marama o te tuku.

Hei tautapa i te rōpū whakamahi te tae e whai ake Tapa transistors: rōpū He hāngai ki te ira pouri whero, B - kōwhai, C - pouri matomato, D - hiriwa, K - puru, D - Blue, E - White, M - parauri pouri, a - karaka, L - tupeka marama, M - hina.

Momo denoted e te tohu, me ngā tae e whai ake nei.

• KT203 hāngai tapatoru koki (te waewae ki raro, a tika) ranei ira pouri whero.
• KT208 - he porowhita iti (reira he hoki tenei momo o te waehere tae).
• K209 - taimana (ira hina).
• K313 - he tohu e rite te T kōaro (ira karaka).
• KT326 - he kōaro tapatoru rite (parauri).
• KT339 - he tapatoru rite (ira puru).
• KT342 - he hauwhā o te porowhita (ira puru).
• KT502 - hawhe revolution (ira kōwhai); KT503 - he porowhita (ira ma).
• KT3102 - tapatoru tapatoru nga waewae ki runga, a ka mahue (ira matomato pouri).
• KT3157 - waewae o te tapatoru matau ki te maui, me te iho (kahore waehere tae).
• K366 - te reta T (kahore tae).
• KT6127 - kōaro reta P.
• KT632 - e kore tohu mahi (ira hiriwa).
• KT638 - i waho te tohu (ira karaka).
• KT680 - reta G.
• KT681 - rakau poutū.
• KT698 - te reta P.

Tohu i te tau, me te marama, o te hanga

I roto i te runga i GOST 25486-82, te whakamahi i rua reta ranei reta me tau ki te tohu i te rā. Ko te pūāhua tuatahi tohu te tau, me te rua o - te marama. Tenei momo o te waehere e whakamahia e kore anake ki transistors engari ano mo te tahi atu huānga Semiconductor kāinga. I roto i te mea ke rā tohua e wha mati, te rua tuatahi o e hāngai ki te tau, me te whakamutunga - tau wiki. A feruri i te mea kua ā tohu transistors e ōrite ana ki te rā o te whakanao. Tau / tohu: 1986 - U, 1987 - V, 1988 - W, 1989 - X, 1990 - A 1991 - B 1992 - C. 1993 - D, 1994 - E 1995 - F, 1996 - H 1997 - ahau o, 1998 - K 1999 - o L, 2000 - Tane, me ētahi atu tuku marama: .. hāngai nga marama tuatahi e iwa ki te tau 1 ki te 9 (Hānuere - 1 Huitanguru - 2), me te whakamutunga - i te reta tuatahi o te kupu: nuku - I te Whiringa-- N, Hakihea - D.

Transistors i KT-27 casing

E hanga ēnei wāhanga Semiconductor ki te tono rānei te waehere ārepa KarereHuna ranei, arā, o āhua āhuahanga. A feruri i te mea te mea transistors tohu whakairoiro.

• KT972A - kotahi "takoto" tapawhā.
• KT972B - rua tapawhā: mahue e takoto ana, utu tika.
• KT973A - kotahi tapawha.
• KT973B - rua tapawhā.
• KT646A - kotahi tapatoru.
• KT646B - mahue porowhita, tapatoru tika.

I tua atu, i reira he he tae atu māka mutunga o te tinana i te mea whakatau ritenga:

• CT 814 - hina-kirīmi;
• CT 815 - lilac-papura, hina ranei;
• CT 816 - māwhero me te whero;
• CT 817 - hina-matomato;
• CT 683 - papura;
• KT9115 - puru.

kia tohua transistors Series KT814-817 rōpū B anake e poke mutunga, kahore meinga he waehere pūāhua.

Ko te pūnaha Pākehā PRO-irahiko

Tohu transistors me ētahi atu pūrere Semiconductor i ngā kaiwhakanao Pākehā e whai ake. Ko te waehere ko te tāurunga pūāhua. Ko te reta tuatahi ko te rauemi Semiconductor: silicon, germanium, etc. te silicon tino noa, hāngai reira ki te reta V. te tohu i muri - tenei momo o te mea ... Next, hoatu te maha o te raupapa hua. I roto i tenei ruma i reira e rave rahi awhe. Hei tauira, ki te he te tau i te 100 ki te 999, enei āhuatanga he hua-whakaaro whānui, me te mea whakanohoia te pukapuka te ratou (Z10 - A99) i mua, e whakaaro enei Semiconductors o ngā wāhanga motuhake ranei take ahumahi. I tua atu, kia tāpiri ai te wae Tapa katoa tohu atu akatuke'anga. tautuhi reira tika kaihanga o wāhanga Semiconductor.

Ko te pūāhua tuatahi (te rauemi): A - Germany, - Si, C - gallium arsenide, R - cadmium sulfide. Ko te huānga tuarua ko te momo transistor: C - iti-te mana auau iti; D - panguru kaha; F - he kaha-iti nui-auau; G - pūrere maha i roto i te mōkihi kotahi; L - he kaha nui-auau; S - iti whakawhitinga mana; U - he whakakā kaha.

Ko te pūnaha o JEDEC American

US kaihanga o ngā pūrere Semiconductor te whakamahi i te whakawaehere pūāhua, e ngā o ngā huānga e wha. Ko te mati tuatahi tohu te maha o Junctions p-n: 1 - ngōhiko; 2 - transistor 3 - thyristor; 4 - optocoupler. Ko te pukapuka tuarua tohu te rōpū. Ko te pūāhua tuatoru - he tau rangatū o te pūmotu (ngā i 100 ki te 9999). tohu tuawha - te reta hāngai ki te whakarerekētanga pūrere.

Ko te pūnaha Japanese JIS

Kei tēnei pūnaha o te pūāhua, me kei te huānga e rima. hāngai te mati tuatahi ki te momo o te pūrere Semiconductor: 0 - photodiode phototransistor ranei; 1 - ngōhiko; 2 - transistor. Ko te pūmotu tuarua - te pukapuka S, kua whakanohoia ki runga ki ngā wāhanga katoa. hāngai reta i muri ki te momo o te transistor: A - High PnP; I roto i - te PnP iti-auautanga; C - NPN tiketike; D - he auau iti NPN; H - unijunction; J - mara ki N-hongere; K - he mara ki te P-hongere. Ko te hua tau rangatū (10 - 9999) te whai. Last, te rima te huānga - he whakarerekētanga o te pūrere (taea maha te mahue ai). I te tahi taime tono reira me te ono o tohu - ko te taupū atu (te pukapuka N, M S ranei), oia hoi, i te titauraa o te fai ki paerewa motuhake. E kore e te pūnaha Japanese o waehere tae o transistors tono.

huānga SMD

Tohu SMD-transistor he taipe anake. Nā ki te rahi iti o enei āhuatanga e kore e whakamahi waehere tae. e kore e paerewa whakamunatanga Single mo ratou te tīariari. whakamahi katoa tipu production ona tohu. kia roto i te waehere ārepa i roto i tenei take i tetahi ki te e toru pūāhua ārepa. Ia tipu hua ona tepu tohu huānga Semiconductor.
