Akuyona idayidi yokuqala esiyihlaziya kule bhulogi, i-1n4007 i-diode yohlobo lokulungisa, kulokhu, futhi enye yeziningi Izingxenye ze-elekthronikhi ongayisebenzisa ne I-Arduino. Izakhi ze-semiconductor ezingabizi, ezingaba nezinhlelo zokusebenza eziningi.
Isibonelo, lezi ama-diode wokulungisa, njenge-1n4007, bangakusiza ukuguqula isignali isuke ku-AC iye ku-DC njengakumandla kagesi (njengoba ngichazile kule enye indatshana), zisebenzise kwamanye amasekethe lapho kudingeka ukulungiswa kwesiginali kagesi, ekulungiseni amasekethe, abalawuli bamandla kagesi, njll.
Yini i-diode rectifier?
Un i-diode yokulungisa, njenge-1n4007, ingenye yezinhlobo zama-diode laphaya, futhi enye yezindala kunazo zonke. Ngenye yezinto ezilula kakhulu, kepha ukusetshenziswa kwayo njengoba ngishilo vele kuningi futhi kukwenza kubaluleke kakhulu emhlabeni we-elekthronikhi.
Njengoba wazi kahle, igama le-diode livela emandleni alo wokwehlukanisa i-current in imijikelezo emihle yesinye isignali. Ngamanye amagama, kuzovumela ukudlula kwemijikelezo emihle yamandla ashintshanayo lapho ihlukaniswe ngqo. Ngesikhathi semijikelezo engemihle, i-diode ikhonjiswe ngokuhlehla futhi lokhu kuvimbela ukudlula kwamanje kulesi siqondiso.
Ngamanye amagama, beka cishe, luhlobo lokuhlunga oluzovumela kuphela imijikelezo emihle yesiginali ukuthi idlule, ikwazi uku ukubandlulula okungekuhle. Cabanga ngakho konke ongakufeza ngaleli khono ...
Futhi ukuze lokho kwenzeke, khumbula ukuthi lezi zinto zenzelwe ukusebenza ngemvamisa ephezulu lapho zizosebenza kahle khona, zisekelwa ubukhulu bamanje obukhulu noma amandla lapho zingahola ziqonde ngqo, futhi ziqonde voltages kanye ne-inverse ubuningi busekelwa. Labo izici zedatha Yibo okufanele ubabhekele imodeli oyikhethile ukuze ungayicindezeli ngaphezu kwemingcele yayo nokuthi isebenza kahle.
Njengamanye ama-diode, kususelwa ku-a I-PN semiconductor junction, imvamisa i-silicon, yize kungahle kube khona amanye ama-semiconductors afana ne-germanium. Ngokuvamile, bavame ukumelana nokufika ku-200ºC enhlanganweni, amazinga okushisa aphakeme kakhulu, anokumelana okuphansi kakhulu kanye namandla aphansi kakhulu we-voltage voltage.
Izici ze-1n4007
El 1N4007 iyi-diode yokulungisa esetshenziswa kakhulu ezintweni eziningi ezisebenza manje, ikakhulukazi emandleni kagesi ukuvimbela ukunikezwa kwamandla kagesi okungakhi kubangele izinkinga esifundeni esivuthayo ngenxa yokuhlehlisa ubumbano, noma ukunikezwa kwamandla ngesikhathi sokuguqula isignali ye-AC ibe yiDC, njll.
Le diode imelana nemisinga efinyelela ku-1A ngokuqhubekayo ngamandla angahamba kuze kufike ku-700v. Lokho kushiya inqwaba yezenzo ngobuningi bezicelo. Ngaphezu kwalokho, ibuye isekele iziqongo ezithile zamandla we-voltage afinyelela ku-1000v, nemisinga engu-30A.
Kufakwe kufayela le- iphakethe DO-41, ngokuvamile, ngamatheminali ayo amabili ajwayelekile. Ngokuqondene nezinye izici okufanele wazi ukuthi:
- Reverse voltage: kusuka ku-500 kuye ku-700v.
- Ukuphakama kwamandla kagesi: 1000v noma 1Kv
- Ubukhulu bokuqhuma kwamanje: 30a
- Ubukhulu bokuqina kwamanje okuqondile: 1a
- Phambili ukwehla kwamandla kagesi: 1.1 V
- Ibanga lokushisa elisebenzayo: -55 ° C kuye ku-150 ° C. Kwezinye izimo kungasuka ku--65ºC kuye ku-125ºC ngokuya ngomkhiqizi ...
I-pinout ne-datasheet
Kepha i-pinout yakho, Ilula kakhulu. Phambilini bengithi ibinezikhonkwane ezimbili kuphela. Enye yazo i-cathode kanti enye i-anode. Ukuze uhlukanise, kufanele ubheke umugqa ompunga kwelinye lamaphethelo alo emzimbeni we-1n4007. Lowo mkhawulo womugqa yiwona ohambelana ne-cathode (-), kanti omunye umkhawulo uyi-anode (+).
Ngeminye imininingwane ungathola yonke imininingwane ku-datasheet kusuka kumkhiqizi wengxenye ethile oyikhethile. Nakhu onakho isibonelo sayo, kepha khumbula ukuthi kungahle kube khona umehluko omncane komunye nomunye, noma imininingwane eminingi yezobuchwepheshe iyefana.
Intengo nokuthi ungathenga kuphi
Intengo yalolu hlobo lwezinto zikagesi ishibhile ngokweqile, zibiza kuphela amasenti ambalwa we-euro. Ngakho-ke, ayabiza kakhulu. Ungabathola ezitolo ezikhethekile ze-elekthronikhi noma ubathenge ku-inthanethi ezitolo ezinjenge-Amazon. Isibonelo, nayi eminye imikhiqizo ongayithanda:
- Ama-diode wokulungisa ama-5 1n4007
- Ayikho imikhiqizo etholakele.
- Ayikho imikhiqizo etholakele.
- Ama-diode angama-50 1n4007
- 100pcs 1n4007
1n4007 isicelo esiwusizo
Ngaphambi kokuthi ngivele ngikuxhumanise nendatshana lapho ngichaze khona ukusebenza kwe- a amandla kagesi, kepha ukubona ngendlela ebonakalayo yokusebenzisa i-1n4007 nokuthi ungazakhela kanjani ugesi wakho ukuze ufunde ngemigomo eyisisekelo ye-elekthronikhi nale ngxenye, ngikushiya le vidiyo efundisayo ...
para ulwazi oluthe xaxa, unga funda i-athikili engichaze kuyo lezi zigaba lapho nje ukuphakelwa kwamandla kufakwa kumaphayini we, ngokwesibonelo, i-220v AC, kanye namandla kagesi we-DC aphansi akhipha umphumela wawo ...
