V-I Characteristics of PN Junction Diode 

this guy saves lives...

Pardon me for being pedantic, but the reverse breakdown phenomena that you’ve described is caused by the avalanche breakdown, not zener breakdown. Thus the avalanche voltage, not zener voltage. The zener breakdown is a different physical phenomena that occurres not due to ionization, but due to quantum tunneling of electrons via the potential barrier that is higher in energy than the energy of electrons. To be fair, these two breakdown types get mixed up a lot, but still these are two different phenomenas, both of which may take place in semiconductors under various circumstances. Anyway, your lessons are really great, thank you very much for sharing them.

You can't count the no. of students you have saved from backs..💓💓

The breakdown of covalent bond through collision with energetic electron called avalanche not zener breakdown. Zener breakdown is case of direct rapture of bonds by electric field of junction.

After long time I listened ur fabulous voice n teaching.far I'm searching for your videos.i request u to make many more videos on resonance (series,parallel circuits),band width concept, Q factor,n many more problems, concepts on balanced,unbalanced circuits. Please sir complete these concepts,I'm waiting for those videos eagerly..Always my love towards NESO😊😊😊❤❤❤❤💓

Thank you for this platform. Learnt a lot from your lectures. The correct term that should be used at 8:28 is voltage. If we keep on increasing voltage the current will not change...

Very nicely explained sir. It definitely clears all the concepts. Thank you sir

Hi Sir...Really these are good lectures, that you clarify lot of doubts. Kindly make a video on Diode Voltage & Current Derivation..also

A gentleman never writes down his definitions.

Love from Pakistan♥️♥️ you're owesome💯

how can use ADS varactor reverse current volt-ampere characteristic curve?

Itna achá koi ni samjha sakta Sir

Very Well explained!. thank u so much. What are the application of Reverse Bias. Is it significant ? Note: Knee Voltage has not been explained.

Thank you so much for your lectures. Its very helpful. Please share also BJT and FET lectures.

Sir can you please explain why the graph in forward bias region shifts towards left when temperature is increased?

Very nice explanation

this is awesome, like the way you presented it. very different, attractive. just loved it. learnt a lot.

Congratulations for 1m🥳🥳

Why the forward curves comes next one-by-one along right-side direction when constant voltage kept different in transistor.

Draw and explain forward and reverse biased V-1 characteristics of PN junction diode.

why the forward current is not parallel to the positive y axis please reply

you are a genius sir. Thank u very much.

Very useful lecture. Thank you very much.

Why we don't perform reverse bias for silicon diode in lab

very well explained

thxxx u explained very well

Nice explaination sir thank you

Nice explanation sir.. ur lectures helps us to clarify many doubts..thank u so much

What is cutin voltage

Sir, Can you please elaborate why the diode current is in exponential form?

At 6:40 , u made it indian Flag🇮🇳(horizontal)😊😊😊😊

This is so good thank you

very good lectures

tq sir it is very helpful

Thank you very much sir🥳🥳🥳🥳

How to find dynamic resistance using i-v characteristics of diode

the word drift comes into the game when electric field is applied (as drift velocity proportional to electric field) in case of forward bias condition after barrier potential becomes equal to biasing potential the depletion layer vanishes therefore conductivity of minority charge carriers becomes zero ( I-saturation = 0 ) but according to current equation of diode id becomes zero because of Is but we see exponential rise in it how ????????????????????????????

Tqs u so much Sir. I'm grateful to ur sir

Is this current in the forward bias region primarily a diffusion current or a drift current due to the field?

Thanks for working so Fast

What if we dope the diode heavily. Would that reduce the knee voltage (Vd)?

Thank u sir....it mean lot...to we students

How come the the reverse saturation current is same for germanium and silicon ? it is in nano amperes for si and micro ampere range for ge, kindly reply

i a, sorry but you have mixed avalanche breakdown with Zener breakdown. please clarify

What is the equation for I (majority).

Good sir.... Easy understandable

Does the equation for diode current Id stand when the diode enters the breakdown region?

Tq

Sir..! Can we write this as an answer for the v-I characteristics of pn junction diode???

sir, please make video s on nuclear physics

👌👌 sir tnq so much...❤️❤️

Wasn't what we are explained Avalanche Breakdown(As in except the High Doping,Which is true for Zener Diode!).

Thank u

Thank u so much sir. I watch all your videos. Really sir you r great.

Very clear and thorough, thank you.

Are you using Boylestad for reference ?

I m very very grateful

sir ap kon se book fallow kr rahay h?

Great explanation! Which book do you use sir?

awesome

I have a question. How the saturation current is called 'saturation ' ?

What is the difference between breakdown voltage and peak inverse voltage.

Why the voltage remains constant even we increase the external voltage

its good.......tnx

what is the breakdown voltage for simple pn junction diode in reverse bias

thnx

THanks☺

Very well explained. please keep on good work!!

🔥🔥🔥

from which book u get this vast amount of knowledge on semiconductor

It was very helpful . Thank you!

Can anyone explain how reverse saturation current is constant concept wise not formulated? It must inc. with rev. Voltage bec. Drift current is inc. compare to diffusion current. If we take nmbr of minority carriers fix then it must dec. with time as there conc. Continuesly decresing. How it is constant with time and voltage inc.

If any body asking

sir which is a better material for making a diode ge or si

Only once fasakkkk.....!

Sir derivation of shockley Equation

What is Vt?

Any one is there who prepare for ojee...

Anyone preparing for jee 2020

Is dis for 12th?

voice is very low sir

It was vry difficult to understand😓
