Ayisiyo diode yokuqala esiyihlalutya kule bhlog, i1n4007 luhlobo lokuhlengahlengisa diode, kule meko, kwaye yenye yezinto ezininzi Izinto zombane onokuyisebenzisa kunye Arduino. Ixabiso eliphantsi, elicacileyo leemiconductor ezinokuba nobuninzi bezicelo.
Umzekelo, ezi ii-diode zokulungisa, njenge-1n4007, banokukunceda uguqule isiginali esuka kwi-AC iye kwi-DC njengakumbane wamandlanjengoko ndacacisile kwelinye inqaku), Zisebenzise kwezinye iisekethe apho kufuneka ukulungiswa komqondiso wombane, ekulungiseni iisekethe, abalawuli bevolthi, njl.
Yintoni i-diode yokulungisa?
Un isilungisi sedayiphu, njenge-1n4007, yenye yeentlobo zeedayidi phaya, kwaye yenye yezona zidala. Enye yezona zilula, kodwa ukusetyenziswa kwayo njengoko sele ndikhankanyile kuninzi kwaye kuyenza ibaluleke kakhulu kwihlabathi le-elektroniki.
Njengoko usazi kakuhle, igama lediode livela kumandla alo okwahlulahlula i-current imijikelezo elungileyo wesinye isignali. Ngamanye amagama, iya kuvumela ukuhamba kwemijikelezo elungileyo yombane otshintshayo xa icaciswe ngokuthe ngqo. Ngexesha lokujikeleza okungalunganga, i-diode yenziwa polarised ngokungafaniyo kwaye oku kuthintela ukudlula okwangoku kweli cala.
Ngamanye amagama, beka kakuhle, luhlobo lwecebo lokucoca elinokuvumela kuphela imijikelezo elungileyo yomqondiso ukuba idlule, ikwazi uku ucalucalulo olubi. Khawufane ucinge yonke into onokuyiphumeza ngale ndlela ...
Kwaye ukuze kwenzeke, khumbula ukuba ezi zinto zenziwe ukuba zisebenze kumaza aphezulu apho ziya kusebenza ngokufanelekileyo, zixhase ubuninzi obukhoyo ngoku okanye amandla apho ziya kuba nakho ukuqhuba ngqo ngqo, kwaye ngqo Iivolthi e eziguqukayo eziphezulu zixhaswe. Abo Izinto zedatha Zizo ezo ekufuneka uzithathele ingqalelo imodeli ekhethiweyo ukuze ungayityhaleli ngaphaya kwemida yayo kwaye isebenze ngokufanelekileyo.
Njengezinye iidayidi, isekwe kwi Ukudibana kwe-semiconductor ye-PN, ngesiqhelo i-silicon, nangona kunokubakho ezinye iisemiconductors ezinje ngegermanium. Ngokubanzi, bathambekele ekumeleni ukuya kuma kwi-200ºC kwindibaniselwano, amaqondo obushushu aphezulu kakhulu, kunye nokumelana okuphantsi kakhulu kunye neevolthi ezibuyiselwayo eziphantsi kakhulu.
1n4007 Iimpawu
El I-1N4007 yidiode yokulungisa esetyenziswa ngokubanzi kwizixhobo ezininzi zangoku, ngakumbi kumandla ombane ukukhusela umbane ongalunganga ekubangeleni iingxaki kwisekethe etshayo ngenxa yokuguqula ubumbano, okanye ukunikezelwa kwamandla ngexesha lenkqubo yokuguqula isiginali ye-AC ibe yiDC, njl.
Le diode iyamelana nemisinga ukuya kwi-1A ngokuqhubekayo ngombane onokuhamba ukuya kuthi ga kwi-700v. Oko kushiya uluhlu olubanzi lwezenzo ngobuninzi bezicelo. Ukongeza, ikwaxhasa iincopho ezithile zombane obuyela umva ukuya kuthi ga kwi-1000v, kunye nemisinga ye-30A.
Ifakwe ngaphakathi Iphakheji YENZA-41Ngokubanzi, kunye neeterminal zayo ezibini eziqhelekileyo. Ngokubhekisele kwezinye izinto ekufuneka uyazi zezi:
- Ukuguqula umbane: ukusuka kwi-500 ukuya kwi-700v.
- Ukuphakama kwamandla ombane: 1000v okanye 1Kv
- Ukunyuka kwangoku:30A
- Ubuninzi bokuqina ngqo kwangoku:1A
- Phambili ukwehla kwamandla ombane: 1.1 V
- Uluhlu olusebenzayo lobushushu: -55 ° C ukuya kwi-150 ° C. Ngamanye amaxesha inokusuka kwi--65ºC iye kwi-125ºC ngokuxhomekeke kumenzi ...
Ukuphuma kunye nedatha
Ewe i-pinout yakho, Ilula kakhulu. Ngaphambili bendisithi inezikhonkwane ezibini kuphela. Enye yazo i-cathode kwaye enye i-anode. Ukwahlulahlula, kuya kufuneka ujonge umgca ongwevu kwenye yeziphelo zalo emzimbeni we-1n4007. Eso siphelo somtya seso sihambelana ne-cathode (-), ngelixa elinye isiphelo lisi-anode (+).
Ngolwazi oluthe kratya unokufumana Zonke iinkcukacha ezikwiphepha ledatha kumenzi wecandelo elithile olikhethileyo. Nantsi unayo umzekelo wayo, kodwa khumbula ukuba kunokubakho iyantlukwano encinci komnye nomnye, nangona uninzi lweenkcukacha zobuchwephesha ziyafana.
Ixabiso kunye nendawo yokuthenga
Ixabiso lolu hlobo lwezixhobo ze-elektroniki libiza kakhulu, zibiza kuphela iisenti ezimbalwa ze-euro. Ke ngoko, zifikeleleka kakhulu. Ungazifumana kwiivenkile ezikhethekileyo zombane okanye uzithenge kwi-intanethi kwiivenkile ezinje ngeAmazon. Umzekelo, nazi ezinye iimveliso ezinokubangela umdla:
- Iimpawu zokulungisa ezi-5 1
- Akukho mveliso ifunyenweyo
- Akukho mveliso ifunyenweyo
- Iidayidi ezingama-50 1n4007
- Ii-100pcs 1n4007
1n4007 isicelo esisebenzayo
Ngaphambi kokuba ndidibanise inqaku apho ndacacisa ukusebenza kwefayile ukuhambisa umbane, kodwa ukubona ngendlela ebonakalayo ngakumbi ukusetyenziswa kwe-1n4007 kunye nendlela onokwakha ngayo umbane wakho ukuze ufunde ngemigaqo esisiseko ye-elektroniki kunye neli candelo, ndikushiyela le vidiyo ifundisayo ...
ukuba olunye ulwazi, unako funda inqaku endichaze ngalo la manqanaba kwakamsinya nje ukuba unikezelo lwamandla londliwe ukusuka kwimibane eyintloko, umzekelo, i-220v AC, kunye namandla ombane asezantsi ombane we-DC kwimveliso ...
