Npav transistors - yog dab tsi? Hom, tsis thiab yam ntxwv ntawm transistors, cim

Lub transistor ua raws li lub ntsiab tivthaiv ntawm tej circuitry. Nws yog ib tug zoo ntawm reinforcing tseem ceeb. Lub hauv paus ntawm no semiconductor ntaus ntawv yog ib tug silicon los yog germanium siv lead ua. Lub transistors yog unipolar thiab bipolar thiab, raws li, daim teb thiab bipolar. Lawv nrhiav tau ob hom conductivity hom - pem hauv ntej thiab rov qab. Rau beginners, pib xyaum ua xov tooj cua lub ntsiab teeb meem yog cov paub txog lub encoding thiab seev suab ntawm cov ntsiab. Nyob rau hauv no tsab xov xwm peb yuav saib lub ntsiab hom ntawm cov ntaub ntawv, ob qho tib si domestic thiab txawv teb chaws cov khoom raws li tsom xam, uas txhais tau tias npav transistors.

hom ntawm cov ntaubntawv povthawj siv

Manufacturers transistors siv ob lub ntsiab hom encryption - ib cov xim code thiab labeling. Txawm li cas los, tsis yog ib tug los yog rau lwm cov tsis muaj niaj hnub qauv. Txhua tsob nroj ua semiconductor pab kiag li lawm (transistors, diodes, zener diodes, thiab hais txog. D.), Txais nws code thiab xim coding. Yuav Raws li transistors ntawm ib pab pawg neeg thiab lub hom ua los ntawm txawv cov nroj tsuag thiab lawv sau tias txawv. Los yog vice versa: lub ntsiab yog sib txawv, thiab xa mus rau lawv - zoo tib yam. Nyob rau hauv xws li mob, kom paub qhov txawv nruab nrab ntawm lawv tsuas yog nyob rau hauv lub ntxiv nta. Piv txwv li, qhov ntev ntawm lub opposite xim tshawb pom emitter thiab collector yog (los yog pem hauv ntej) nto. Npav FETs yog tsis sib txawv ntawm lub cim npe nyob rau lwm lub pab kiag li lawm. Cov tib qhov teeb meem no yog nrog semiconductor ntsiab ntawm txawv teb chaws keeb kwm: txhua chaw tsim tshuaj paus siv lawv hom designations.

Transistors nyob rau hauv kt-26 casing

Xav txog hais tias cov qhab nia transistors ua domestically. Qhov no hom ntawm lub tsev yog feem ntau nrov ntawm semiconductor manufacturers. Nws muaj ib tug cylindrical zoo nrog ib tug bevelled sab, peb cov lus xaus muaj los ntawm lub sab puag. Nyob rau hauv cov ntaub ntawv no, nws siv lub hauv paus ntsiab lus ntawm ib tug tov npav thiab muaj code cim, thiab cov xim. Nyob rau Upper puag yog xim-point, lub ntsiab lus transistor pab pawg neeg, thiab ib tug tapered sab - code cim los yog xim taw tes coj mus rau lub ntaus ntawv hom. Nyob rau hauv tas li ntawd mus ntaus, yuav tsum muaj ntaub ntawv mus rau lub xyoo thiab lub hli ntawm tso tawm.

Yuav kom xaiv ib pab pawg neeg siv cov nram qab no xim coding transistors: pab pawg neeg A sau raws nkaus Ii ib tug maub liab teev, B - daj, C - tsaus ntsuab, D - xiav, D - Blue, E - Dawb, M - tsaus xim av, thiab - silver, K - txiv kab ntxwv, L - lub teeb haus luam yeeb, M - grey.

Hom denoted los ntawm cov nram qab no cov cim thiab cov xim.

• KT203 hnov angled daim duab peb sab (lub ob txhais ceg thiab txoj cai) los yog tsaus liab teev.
• KT208 - ib tug me me lub vajvoog (muaj yog rau no hom ntawm cov xim coding).
• K209 - pob zeb diamond (grey dot).
• K313 - ib lub cim uas tsa ib tus inverted lub T (txiv kab ntxwv teev).
• KT326 - ib tug inverted equilateral daim duab peb sab (xim av me ntsis).
• KT339 - ib tug equilateral daim duab peb sab (xiav teev).
• KT342 - ib tug peb lub hlis twg ntawm ib lub voj voog (xiav teev).
• KT502 - ib nrab kiv puag ncig (daj dot); KT503 - ib lub voj voog (dawb dot).
• KT3102 - angled daim duab peb sab ob txhais ceg thiab sab laug (tsaus ntsuab dot).
• KT3157 - ob txhais ceg ntawm ib txoj cai daim duab peb sab mus rau sab laug thiab down (tsis muaj xim coding).
• K366 - tsab ntawv T (tsis muaj xim).
• KT6127 - inverted tsab ntawv P.
• KT632 - Cim ua tsis (silver point).
• KT638 - tsis muaj tus cim (txiv kab ntxwv teev).
• KT680 - tsab ntawv G.
• KT681 - ntsug wand.
• KT698 - tsab ntawv P.

Npav lub xyoo thiab lub hli uas siv

Nyob rau hauv raws li GOST 25486-82, siv ob tug tsiaj ntawv los yog cov tsiaj ntawv thiab ua zauv los qhia hnub. Tus thawj cim nruab nrab yog cov xyoo, thiab lub thib ob - ib lub hlis. Qhov no hom ntawm coding yog siv tsis tsuas mus rau transistors tab sis kuj rau lwm domestic semiconductor ntsiab. Nyob rau hauv txawv teb chaws seev hnub qhia los ntawm plaub tug lej tom qab, cov thawj ob tug uas sib haum mus rau hauv lub xyoo, thiab lub xeem - lub lim tiam tooj. Xav txog dab tsi yog coded npav transistors coj mus rau lub hnub tim ntawm siv thiab ua. Xyoo / lub cim: 1986 - U, 1987 - V, 1988 - W, 1989 - X, 1990 - Ib tug 1991 - B 1992 - C. 1993 - D, 1994 - E 1995 - F, 1996 - H 1997 - kuv ntawm, 1998 - K 1999 - ntawm L, 2000 - M, etc. tso tawm rau lub hlis: .. thawj cuaj lub hlis sib haum mus rau tus xov tooj ntawm 1 mus rau 9 (lub ib hlis ntuj - 1 lub ob hlis ntuj - 2), thiab lub xeem - thawj zaug cov tsiaj ntawv ntawm cov lus: lub kaum hli ntuj - Nyob rau lub kaum ib hlis - N, Hlis ntuj nqeg - D.

Transistors nyob rau hauv kt-27 casing

Cov semiconductor Cheebtsam yog ua mus thov yog ib tug alphanumeric code los yog cipher, muaj raws ntawm geometric duab. Xav txog dab tsi yog duab npav transistors.

• KT972A - ib tug "dag" duab plaub.
• KT972B - ob voos: sab laug dag, txoj cai muaj nqis.
• KT973A - ib tug square.
• KT973B - ob squares.
• KT646A - ib daim duab peb sab.
• KT646B - tshuav lub vajvoog, txoj cai daim duab peb sab.

Tsis tas li ntawd, muaj yog ib tug ntxiv xim npav rau thaum xaus ntawm lub cev uas yog opposite cov lus xaus:

• CT 814 - grey-beige;
• CT 815 - lilac-ntshav, los yog txho;
• CT 816 - liab thiab xim liab;
• CT 817 - grey-ntsuab;
• CT 683 - ntshav;
• KT9115 - xiav.

Transistors Series KT814-817 pab pawg neeg B tej zaum yuav tau cim nkaus xwb los ntawm uas tseg tau kawg tsis tas yuav ua ib tug cim code.

Cov nyob sab Europe system PRO-electron

Npav transistors thiab lwm yam semiconductor li ntawm European manufacturers raws li nram no. Lub code yog ib tug cim nkag. Tus thawj tsab ntawv yog ib tug semiconductor khoom: pob zeb ntais, germanium, etc. Cov feem ntau pob zeb ntais, nws sau raws nkaus Ii mus rau tsab ntawv V. Cov tom ntej no cim - no hom ntawm kev ntsuas ... Tom ntej no, muab tso rau hauv lub xov tooj ntawm cov khoom series. Nyob rau hauv cov chav no muaj ntau ntau hom twg. Piv txwv li, yog hais tias tus xov tooj yog los ntawm 100 mus 999, cov ntsiab yog general-lub hom phiaj cov khoom, thiab yog hais tias tus ntawv no yog muab tso rau ua ntej lawv (Z10 - A99), cov semiconductors pom tau hais tias ntawm tshwj xeeb qhov chaw los yog muaj lub hom phiaj. Tsis tas li ntawd, tag nrho cov cai tsev tej zaum yuav muab ntxiv ntxiv kev hloov kho lub cim. Nws txhais ncaj qha chaw tsim tshuaj paus ntawm semiconductor Cheebtsam.

Tus thawj cim (cov ntaub ntawv uas): A - Lub teb chaws Yelemees, - Si, C - gallium arsenide, R - cadmium sulfide. Qhov thib ob lub caij no yog ib tug transistor hom: C - muaj hwj huam tsawg zaus; D - haib ntses bass thaj tsam; F - ib tug muaj hwj huam high-zaus; G - ntau pab kiag li lawm nyob rau hauv ib lub pob; L - ib tug haib high-zaus; S - tsis muaj hwj chim switching; U - ib tug haib mus.

Cov American system ntawm JEDEC

US manufacturers ntawm semiconductor li siv ib tug cim encoding, uas muaj plaub hais. Tus thawj tug lej nruab nrab yog cov xov tooj ntawm p-n junctions: 1 - diode; 2 - transistor 3 - thyristor; 4 - optocoupler. Qhov thib ob tsab ntawv qhia cov pab pawg neeg. Qhov thib peb cim - ib tug naj npawb ntawm lub caij (ntau los ntawm 100 mus 9999). Plaub lub cim - tsab ntawv sib nug xov mus rau lub ntaus ntawv hloov kho.

Cov Japanese system JIS

Qhov no system muaj cov cim thiab muaj lub tsib ntsiab. Tus thawj tug lej sau raws nkaus Ii mus rau lub hom ntawm cov semiconductor ntaus ntawv: 0 - photodiode los yog phototransistor; 1 - diode; 2 - transistor. Qhov thib ob lub caij - tsab ntawv S, nws yog muab tso rau tag nrho cov Cheebtsam. Tom ntej no tsab ntawv sau raws nkaus Ii mus rau lub hom transistor: A - High PNP; Nyob rau hauv - cov tsawg zaus PNP; C - siab NPN; D - ib tug tsawg zaus NPN; H - unijunction; J - teb nrog N-channel; K - ib tug teb nrog ib tug P-channel. Cov nram qab no yog cov khoom serial tooj (10 - 9999). Lub Xeem, Lub tsib lub caij - ib tug kev hloov kho ntawm tus ntaus ntawv (nws tau feem ntau yuav rho). Tej zaum nws thov thiab thib rau lub cim - yog ib tug ntxiv index (cov tsiaj ntawv N, M los yog S), lub ntsiab lus qhov yuav tsum tau conformity kom meej qauv. Cov Japanese system ntawm cov xim coding ntawm transistors tsis thov.

SMD ntsiab

Npav SMD-transistor yog tsuas leb. Vim lub me me luaj li cas ntawm cov ntsiab tsis txhob siv cov xim coding. Tib encryption txheem rau lawv tsis muaj nyob. Txhua ntau lawm cog siv nws lub cim. Lub alphanumeric code nyob rau hauv cov ntaub ntawv no tej zaum yuav muaj los ntawm ib mus rau peb alphanumeric cim. Txhua tsob nroj ua nws ntxhuav cim semiconductor ntsiab.
