Mai suna DIAC?

Mai DIAC shi ne?

Ta'afin DIAC

DIAC yana nufin dioda wanda ya faru da hanyar karamin kirkiro na jiki ba tare da rike cikin tsarin karamin kirkiro na jiki don gudanar da sauran karamin kirkiro.

DIAC yana nufin dioda wanda ya faru da hanyar karamin kirkiro na jiki ba tare da rike cikin tsarin karamin kirkiro na jiki (VBO) ya samu. DIAC yana nufin “Dioda don Kirkiro na Jiki”. DIAC yana nuna abubuwa da biyu masu maza, kuma yana cikin alummomin thyristor. Ana amfani da DIACs a cikin gudanar da thyristors. Tushen da ta nan yana nuna alama na DIAC, wanda yake da tasiri mai kyau da idan an saka duwodiode a birni.

DIACs bai da maza na gate, ba kamar wasu daga cikin thyristors da suke amfani da su don gudanar, kamar TRIAC.

Zaɓar DIAC shine ya zama a iko ko karfi bayan da aka rage rike cikin avalanche breakdown voltage.

Ana yi amfani da DIAC a matsayin transistor baki daya. Yana iya iko ko karfi da hanyar rike musamman da kuma haske, kuma ya ci gaba a cikin avalanche breakdown.

Bunowa DIAC

Wannan yana nuna abubuwa da biyar da maza biyu. Bunowan yana da muhimmanci da ke ciki a cikin transistor. Amma akwai abubuwa masu iyakoki wadanda suke gudanar da bunowan transistor. Abubuwan da suke gudanar da su shine-

• Ba a kan maza na base a DIAC

• Tasankuka uku suna da muhimmanci da muhimmanci a fadada doping

• Yana bayar da ingantaccen gudanar da hanyar rike musamman da kuma haske

Ingantattun DIAC

Daga tushen da ta nan, ana iya tabbatar da cewa DIAC yana nuna p-type material biyu da kuma n-type materials uku. Kuma babu maza na gate a cikinsu.

DIAC yana iko da hanyar rike musamman da kuma haske. Idan A2 yana da hasken da ya fi A1, wannan ya zama ba a ci N-layer ma a ci P2-N2-P1-N1. Idan A1 yana da hasken da ya fi A2, wannan ya zama a ci P1-N2-P2-N3. Bunowan yana nuna diode da a saka a birni.

Idan rike da aka rage yana da haɗuwa a hukuma, karamin kirkiro mai yawa yana faru saboda drift of electrons and holes a cikin depletion region. Ba sai dai karamin kirkiro yana faru, ba ya fi zama avalanche breakdown, saboda haka abubuwa ta zama a cikin yanayi ba.

Idan rike da aka rage yana da ita cikin avalanche breakdown voltage, karamin kirkiro na DIAC yana zama, saboda haka yana faru da hanyar V-I characteristics.

V-I characteristics yana nuna English letter Z. DIAC yana ci yanayi idan rike yana da haɗuwa cikin avalanche breakdown voltage. Don in karfar da abubuwa, ya kamata rage rike cikin avalanche breakdown voltage.

Amfani da DIAC

Amfani na mafi muhimmanci na DIAC shine a cikin TRIAC triggering circuit. DIAC yana saka da maza na gate na TRIAC. Idan rike a kan gate yana rage cikin ɗaya, rike a kan gate zai zama zero, kuma TRIAC zai karfa. Wasu amfanan da za su iya amfani da DIAC shine:

• Yana iya amfani a cikin lamp dimmer circuit

• Yana amfani a cikin heat control circuit

• Yana amfani a cikin speed control of a universal motor

DIAC yana iya amfani da TRIAC a birni don gudanar. Maza na TRIAC yana saka da terminal na DIAC. Idan rike da aka rage a kan DIAC yana da ita cikin avalanche breakdown voltage, wannan zai iko.

Idan rike a kan DIAC yana rage cikin avalanche breakdown voltage, abubuwa zai karfa, kuma TRIAC da a saka shi zai karfa.

Kammalawa na DIAC

DIAC yana cikin abubuwan da suka fiye a cikin alummomin thyristor.

Zaɓar amfani da wannan abubuwa shine-

• Ba ya ci gudanar da low voltage condition a low current level kamar SCR ko TRIAC.

• Yana da low on state voltage drop har zuwa lokacin da current yana rage cikin holding current level.

• Voltage drop yana rage cikin current.
