Sida Loo Iftiimo Diode-ka Iftiinka

Intee in le'eg ayaad ka taqaannaa dareeraha dhaldhalaalka ah? Baahida suuqa diode-ta iftiinka maanta waa mid ballaaran. Kuwa loo isticmaalo nalalka waddooyinka, aaladaha caafimaadka, nalalka baabuurta, kamaradaha, nalalka tilmaame koronto iyo goobo kale ayaa dhammaantood ku lug leh. Maanta, tifaftiruhu wuxuu inta badan rabaa inuu sharaxo sida loo shido diode-yada iftiinka. Tusaale ahaan u soo qaado iftiinka tusaha; marka diodeheena iftiinka ah uu ku xiran yahay AC 220V, waxaa loo isticmaalaa tilmaame koronto ah, habka ugu fududna waa in lagu xiro resistor-xaddidan hadda. Marka loo eego nooca diode-yada iftiinka ee soo baxaya cabbirka. Diode guud ee iftiimiya waa 2.8-3.4V, qalabka midabada kala duwani waa kala duwan yihiin, danabkuna waa kala duwan yahay. Hadda tubbada ifaysa ee dhalaalka sare leh, 10mA ee hadda jira ayaa horeba u iftiimay. Diode iftiinka guud ee soo baxaya, qiimaha hadda shaqeeya waa 1mA-15mA. Iftiinka gaarka ah waxaa lagu beddeli karaa iyadoo la hagaajinayo cabbirka caabbinta xadka hadda. Mabda'a ugu muhiimsan ee diode iftiiminta iftiinka ayaa dhab ahaantii ah in la sameeyo caqabad suurtagal ah iyada oo loo marayo danab dhammaadka ah ee PN knot. Marka booska korantada eexda togan hoos u dhacdo, inta badan sideyaasha aagga P iyo aagga N waxay ku faafaan dhinaca kale. Sababtoo ah heerka guuritaanka elektaroonigga ah aad ayuu uga weyn yahay heerka socdaalka hawada acupoint, tiro badan oo elektaroonik ah ayaa ku fida aagga P, samaynta duritaanka sidaha tirada yar ee aagga P. Electrons-yadani waxay ka soo baxaan godka qiimaha, tamarta la helay inta lagu jiro isku-dhafka ayaa lagu sii daayaa qaabka tamarta iftiinka. Tani waa mabda'a PN knot dhalaalaya. Inta kor ku xusan waa qaar ka mid ah sharraxaadaha iftiiminta ee ku saabsan diode iftiimiya iftiinka maanta, kaas oo uu soo koobay tafatiruhu. Haddii aad rabto inaad ogaato macluumaad dheeraad ah oo ku saabsan diode iftiin-bixiya ama iibso badeecad, waxaad si toos ah ula xiriiri kartaa adeegga macaamiisha khadka tooska ah, ama wac taleefanka xiriirka si aad ula tashi u sameyso.
