- In this video, the diode and its V-I characteristics have been explained.
The following topics have been discussed in the video.
0:43 What is Diode?
1:53 V-I characteristics of Diode
3:57 Ideal Diode and it's V-I characteristics
6:49 The ideal diode with the threshold voltage
10:04 The ideal diode with a threshold voltage and resistance

What is a diode?
The diode is two terminal semiconductor element which allows the flow of current in one direction. (It's unilateral element)
The one terminal of the diode is known as the anode and another terminal is known as the cathode.
Forward Bias:
when the applied voltage across the anode and cathode is positive then the diode allows the flow of current and it is said to be forward biased.
Reverse Bias:
If the applied voltage is negative then it will not allow the flow of current and diode is said to be reversed biased.
V-I characteristics of the diode:
Using V-I characteristics of the diode, it is easy to find the voltage and current in the circuit which contains the diode.
The diode is a non-linear element. It means the relationship between voltage and current is non-linear. Because of the non-linear relationship, it is a bit difficult to analyze the circuit which has a diode.
And to analyze the circuit, different diode approximations are used.
In the video, different diode approximations have been discussed.
At the end of the video, different diode parameters have been discussed.
This video will be helpful to everyone for getting the basic overview of the diode and understanding the V-I characteristics of the diode.

This, sir, was amazing! It cleared up many things for me personally, you have a fine method of teaching, that is very much appreciated!
Thank you for your great contribution to my education.you are teaching in understandable way.thank you alot
Sir I really love your videos, it's too good and you teach in very simple ways,...😇😇😇
The best video I have seen explaining diodes in an intuitive way that is easy to understand. Subscribed to your channel!
I am actually watching your videos because I wish to learn about solar cells. I understand solar cells are essentially PN junction diodes which is why I am watching your video. Aside from semiconductor physics, diodes, pn junction diodes, what else should I learn about so that I am fully ready to learn about solar cells?
Would be grateful if you can answer my question :D
Buy a book on electronics.
Better than my class teacher ❤
i came across this channel during my electronics class, and i think i am saved

Will u PLEASE make some video over transistor like
BJT and FET or MOSFET
Good explanation how diode works
Watch this also
Extraordinary
Very nice
Good video
Will you do videos regarding BJT and FET transistors?
Hello, I am interested in translating the subtitles to your videos in Greek.
can you do turkish bro?
thankyou sir
In reverse bias the current is not zero.current flows in the order of microamperes.so we neglect it
Thanks
My man
Sir please the dialogue you used to explain should be in downwards it is hard to see the problems you done• it can't be seen in the video so please take action on this
Please give a link for notes also as you are so fast 🙂
Sir
May I ask u ..which software do you use for making videos
0:51 Resistor allows current in both directions or doesn't allow current? I didn't understand what you meant to say. Please explain.
Nicely explained...can u tell me..how can one identify the material of the diode by observing the v-i characteristics of a diode?
For, germanium the forward voltage drop is around 0.2 to 0.3V, while for silicon it is 0.6 - 0.7V.
From the V-I characteristics, the point (on voltage axis) from where the current starts increasing gives the approximate idea of the forward voltage drop of the diode.
And from that, you can know whether it is silicon or germanium. (For other materials, the voltage drop will be different)
@@ALLABOUTELECTRONICS thank you sir😊
Tq
Very nice video, left a like, HOWEVER if on a mobile device, the subtitle will block the equation
Sir are this videos enough for Analog Electronics GATE Preparation?
Yes, for analog electronics, most of the topics are covered in the playlist(with examples). And the remaining topics will also be covered soon.
ur videos are pretty good but u talk too fast
just try to talk slowly so we can understand
Please put the zener diode and its solved problems videos in this playlist
I have already made videos on it and have put them in the playlist.
Please check the playlist on the diode, you will get it.

What is Saturation region
May I get the study material? It is helping me a lot. Thanks brother
Sir please provide us notes
Are you teaching or reading paragraph... sorry but it took a lot of effort to see whole video
Correct ,Some improvement is needed , still for your efforts i liked video
Super sir. Suggest the best book to learn Electronics
Electronic Principles by Albert Malvino and Electronic Devices and Circuit Theory by Boylestad / Nashelsky, for understanding the basics.
@@ALLABOUTELECTRONICS okay sir
11:34 what are you correcting with the "In series with" ?
"across the diode," it should be, in series with the diode, thus the correction.
It's all what I needed but you are speaking fast , it will be better if u speak little slow.
is there a link to the pdf notes of this channe; ?
11:25 what are you correcting with the "In series with Diode" ?
What I mean to say was, if the equivalent resistance in series with the diode is much more than the diode forward resistance, then for simplicity the diode the resistance can be neglected.
Diode resistance is typically a few ohms. But the load resistance or the equivalent resistance, in series with the diode, is much more than that, (few kΩ), then diode resistance can be neglected.
In the video, instead of in series, I told across the diode.
I hope it will clear your doubt.
Why the voltage of diode increase sharply after some time
That's the characteristics of the diode. Once the applied voltage is more than the barrier potential of the diode, it starts conducting and it offers very low resistance. That's why the current increase sharply. You can visualise it as controllable switch.
Sir u told that for ideal diode it flows the current before threshold voltage.but while the curve representation you shows that current flow after threshold voltage🤔🤔.please explain once it clearly sir🙏🙏
For analysis, different diode approximations are used.
When the diode is considered as the ideal diode, then it will conduct when the voltage between the anode and cathode is positive. (The first approximation)
In the second approximation, it will conduct when the voltage across the diode is greater than the threshold voltage. But otherwise, the diode is ideal. That means after that it will act as a closed switch. (No resistance, hence vertical line)
In the third approximation, the resistance of the diode is also considered during the analysis.
So, after the threshold voltage, there will be a linear increase in the current. (But still, it is an approximation because actually the current increase exponentially with the voltage)
So, in short, depending on the type of analysis, any of the following approximations are used.
Here during the representation in the curve, I have shown the second approximation where the diode conducts after the threshold voltage.
I hope it will clear your doubt.
@@ALLABOUTELECTRONICS thank you so much sir.for this brief information🤗🤗🤗.sir please try to do one more video on clipping series circuit example problems (or) if you know any site then suggest me sir
@@cheerladinnemouli2864 I have already made a separate video on solved problems on clipper and clamper circuit.
Please check the playlist on the diode circuit. You will get it.
@@ALLABOUTELECTRONICS I already watched that video sir.anyway thank you very much sir.your lectures really super😇😇.keep on upload the videos
@@ALLABOUTELECTRONICS please add this also in discription it will be helpful to others
mighty mighty MIT
Thank you Sir,
What happens if the diode reaches to breakdown region... will it get damaged? When the negative voltage is applied the no current flows in circuit then why reverse saturation current occurs?? What is the use of this reverse saturation current??
Yes, If the normal diode is used in the breakdown region for a longer time, then it can damage the diode. Regarding your second question, the reverse saturation current is very small. (typically in uA or even less).
Please go through the next video in the diode series, I have explained that.
Here is the link of the playlist : ua-cam.com/play/PLwjK_iyK4LLBj2yTYPYKFKdF6kIg0ccP2.html
@@ALLABOUTELECTRONICS Thank you sir
why silicon is preferred more than germanium inspite of high threshold voltage...?
The germanium has more reverse saturation current than silicon at the given temperature and voltage. The reverse saturation current tends to increase with temperature. For germanium, it increases more rapidly than silicon. And moreover, that silicon is available in abundance in nature. So, not only in diode but in almost all semiconductor devices silicon is used.
00:00:43 Kono DIOde Da!
❤️
what will happen if a normal diode enters breakdown region?
For normal diode, the breakdown region should be avoided. It can damage the diode.
Special diode??
