Diode क्या है और Diode के प्रकार

kyaa aap jaante hain ki ye daayod kyaa hai (What is Diode in Hindi) yadi aap kabhi kisi Electorinics ke dukaan ko gaye honge tab aapne shaayad ye chhote se semiconductor device ko dekhaa bhi hogaa. lekin jaankaari ke hone se aapne shaayad ese pahchaanaa bhi nahin hogaa. vaise aapke jaankaari ke lia bataa dun ki ye Diode bahut hi simplest two-terminal unilateral semiconductor device hote hain. ye diode ‘one way‘ sign hote hain electrical circuits ke. esmen current ko keval ek hi direction men flow hone ke lia allow kiyaa jaataa hai. pratyek diode men ek positive end hotaa hai, jise ki Anode kahaa jaataa hai, aur ek negative end bhi hotaa hai jise ki cathode kahaa jaataa hai.

Current hameshaa anode se cathode ki aur bhi flow kartaa hai, lekin kabhi bhi ultaa nahin. en Diodes ke bahut saare upyogitaayen hain jiske vishay men aaj ham es article daayod ki paribhaashaa jaanenge. esalia aaj mainne sochaa ki kyun n aap logon ko Diode aur uske prkaaron ke vishay men puri jaankaari prdaan ki jaaye jisse aapko es electronic device ko behatar rup se samajhne men aasaani hogi. to binaa deri kiye chalia shuru karte hain aur jaante hain ki sahi men ye daayod kyaa hoti hai hindi men.

daayod kyaa hai (What is Diode in Hindi)


yah ek aisaa Electronic Component hotaa hai jo karant ko sirph ek dishaa men Flow hone ki anumati detaa hai. Diode men do tarah ke elektrod hote hai enod aur kaithod. Diode men jo silvar kalar ki laaen hoti hai us taraph kaa elektrod kaithod hotaa hai aur Diode ke Symbol men jo traayangal ki nok hai uski dusri taraph vaalaa enod hotaa hai.

kyaa aap jaante hai daayod kyaa kaam kartaa hai? Diode bhale hi dikhne men chhotaa hotaa hai lekin eske kaary bahut bde hote hai. esko ham Rectifiers, Signal Limiters, Voltage Regulators, Signal Modulators, Signal Mixers aadi ke rup men estemaal kiyaa jaataa hai. jab Diode kaa kaithod tarminal ko negetiv voltej aur enod ko pajitiv voltej se jod dete hai to karant bahne lagtaa hai aur ese phoravard baayasing kahte hai.

daayod kaise kaam kartaa hai


ye diode tab operate karte hain jab ki ek voltage signal ko apply kiyaa jaaye eske terminals ke across. Circuit ko operate karne ke lia jab DC voltage ki application ki jaati hai tab es prakriyaa ko ‘Biasing’ kahaa jaataa hai. jaise ki mainne pahle hi bataayaa hai ki ye diode resemble karti hai one way switch ko jisse ki ye yaa to conduction ke state men hotaa hai yaa phir non conduction ke state men.

Diode men ‘ON’ state ko achieve kiyaa jaataa hai ‘Forward biasing’ ke dvaaraa jiskaa matalab hotaa hai ki positive yaa higher potential ko apply kiyaa jaaye anode ko aur negative yaa lower potential apply kiyaa jaaa cathode ko ek diode men. ese dusri bhaashaa men samjhen to, Diode ke ‘ON’ state men applied current, arrow head ke samaan direction men stith hotaa hai.

Diode men ‘OFF’ state ko achieve kiyaa jaataa hai ‘Reverse biasing’ ke dvaaraa jiskaa matalab hotaa hai ki positive yaa higher potential ko apply kiyaa jaaye cathode ko aur negative yaa lower potential ko apply kiyaa jaaye anode ko ek diode men. ese dusri bhaashaa men samjhen to, Diode ke ‘OFF’ state men applied current, arrowhead ke ulti direction men stith hotaa hai.

ye ‘ON’ state men, practical diode ko ek resistance kaa saamnaa karnaa pdtaa hai jise ki ‘Forward resistance’ kahte hain. ye diode ko ek forward bias voltage ki jarurat hoti hai use ‘ON’ condition men switch karne ke lia, es voltage ko Cut-in-voltage khaa jaataa hai.

Diode reverse biased mode men conduct karne lagtaa hai jab reverse bias voltage apni limit ko exceed kar letaa hai, esi voltage ko Breakdown voltage khaa jaataa hai. ye diode ‘OFF’ state men stith hotaa hai jab koi bhi voltage uske across apply n kiyaa jaaye tab.

ek simple p-n juction diode ko fabricate kiyaa jaataa hai bas p aur n type layers ko doping kar ek silicon yaa germanium wafer men.

ab aap soch rahe honge ki kyun Silicon aur Germanium materials ko kyun prefer kiyaa jaataa hai fabrication ke lia, tab eskaa javaab hotaa hai : –

ye materials high purity men available hote hain.

esmen ek Slight doping jaise ki one atom per ten million atoms ek desired impurity men hone se ye conductivity ko badal kar rakh sakti hai ek considerable level men.

en materials ki properties change ho jaati hai jab heat aur light ko apply kiyaa jaataa hai aur esalia ye mahatvpurn hotaa hai heat aur light sensetive devices ko develop karne men.

daayod ke prkaar

daayod auph aul taaeps: bahut prkaar ke daayod hote hai, jaise jenar daayod, surang daayod, ardhchaalak daayod, paavar daayod, etyaadi. yahaan aapko sabhi ki jaankaari milegaa aur voh kis lia estimaal kiye jaate hai.

1. Zener Diode

eskaa aavishkaar 1934 men Clarence Zener ne kiyaa thaa. yah ek saadhaaran Diode ki tarah karant ko ek hi dishaa men jaane detaa hai lekin jab voltej brekdaaun voltej se jyaadaa ho jaataa hai to yah karant ko ulti dishaa men bhi jaane detaa hai. eskaa aavishkaar ekadam se aane vaali voltej se bachne ke lia kiyaa gayaa thaa. yah Diode ek voltej reguletar ki tarah kaam kartaa hai.

2. Constant Current Diodes

es Diode kaa mukhy kaam voltej ko vishesh karant par niyamit rakhnaa hai. es karant limited daayod yaa daayod kanekt traanjistar bhi kahte hai.

3. Shockley Diode

yah pahlaa Pnpnleyar vaalaa semikandaktar Diode thaa. eskaa aavishkaar 1950 ke dashak men William Shockley ne kiyaa thaa aur es Diode kaa naam bhi unhi ke naam par rakhaa gayaa.

4. Light Emitting Diode (LED)

yah Diode elektranik enarji ko laaet enarji men badaltaa hai. ese prkaash utsarjak daayod bhi kahaa jaataa hai. eskaa aavishkaar 1968 men kiyaa gayaa thaa. yah Diode pharavard baayos ki sthiti par kaam kartaa hai. pahle es Diode kaa estemaal endaktar laimp men kiyaa jaataa thaa lekin ab eskaa estemaal bde star par hone lagaa hai. ab ese traiphik signal ke kaimron men bhi yuj kiyaa jaane lagaa hai.

5. Schottky Diode

yah Diode semikandaktar materiyal aur dhaatu ke jankshan ke dvaaraa bani hoti hai. esmen voltej kam draap hoti hai. esmen dhaatu hone ke kaaran yah Diode bahut adhik maatraa men karant bahaane ki kshamtaa rakhti hai. es Diode kaa naam jarmni ke Physicist Walter H. Schottky ke naam par rakhaa gayaa thaa.

6. Tunnel Diode

bahut teji se svich karne ke lia es daayod kaa estemaal kiyaa jaataa hai. jis jagah kaary naino sekand men karvaanaa ho vahaan eskaa yuj kiyaa jaataa hai. eskaa aavishkaar 1957 men Leo Esaki dvaaraa kiyaa gayaa thaa, esalia ese Esaki Diode bhi kahte hai.

7. Varactor Diode

yah vairiyebal kaipisitar ki tarah kaam kartaa hai. esko bahut saare upakarnon men estemaal kiyaa jaataa hai jaise sel fon, saitelaaet, pri-philtars aadi.

8. Laser Diode

ese LD yaa enjekshan lejar daayod ke naam se bhi jaanaa jaataa hai. yah Light Emitting Diode ki tarah hi kaary kartaa hai. lekin yah laaet ki jagah ek lejar bim banaataa hai. eskaa upyog aaj ke samay men phaaebar auptik, baarkad ridars, lejr paentars, CD/DVD aadi men hotaa hai.

daayod kaa kyaa kaam hai

chalia Diode ke uses ke vishay men aur adhik jaankaari praapt karte hain.

Rectification – esmen rectification kaa matalab hotaa hai AC voltage ko DC voltage men convert karnaa. jo common rectification circuits kaa jyaadaa estmaal hotaa hai vo hain half wave rectifier (HWR), full wave rectifier (FWR) aur bridge rectifier.

Half wave rectifier: ye circuit rectify karte hain yaa to positive yaa phir negative pulse ko input AC ki.

Full wave rectifier: ye circuit convert karti hai entire AC signal ko DC men.

Bridge rectifier: ye circuit convert karti hai entire AC signal iko DC men.

Clipper – Diode kaa estmaal kisi pulse ke kuchh portion ko clip off karne ke lia bhi estmaal kiyaa jaa saktaa hai binaa koi distortion paidaa kiye waveform ke baaki hisson men.

Clamper – ak clamping circuit restrict kartaa hai voltage levels ko ek limit ko exceed karne ke lia, jiske lia unhen DC level ko shift karnaa hotaa hai. es clamping men peak to peak ko koi bhi affect nahin hogaa. en Clamping circuits men un Diodes kaa estmaal kiyaa jaataa hai jismen ki resistors aur capacitors hon. kabhi kabhi independent DC sources kaa estmaal kiyaa jaataa hai koi additional shift prdaan karne ke lia.

eskaa upyog Alternate Current ko Direct Current men badalne ke lia kiyaa jaataa hai.

taapmaan maapne men eskaa yuj kiyaa jaataa hai.

Radio Demodulation men bhi Diode kaa yuj kiyaa jaataa hai.

sarkit men karant ko modne ke lia eskaa estemaal hotaa hai.

ovar voltej protekshan ke lia Diode kaa yuj kiyaa jaataa hai.

Voltage Regulator aur Signal Mixing men eskaa yuj kiyaa jaataa hai.
