Hey man just to say thank you so much for all you did in these series up until now, it has been incredibly helpful to take someone who knew noothing about electronics to a place where I start to feel like I have a grip on the basics, incredible!! You are an excellent teacher. If you find the time and energy to continue with these videos there will be many appreciative people as I'm sure you have gathered already by the many positive comments, myself included. And if not, then I'm still very grateful for everything you have put up until now!
Your videos are amazing and helps a lot but in indian schools we are taught these only on paper and we dont even know how a diode actually looks irl. Our education system is only about mugging up everything and throwing it up on the day of exam. So learning these things from you is a whole new and different experience and im so thankful to you.
I know this is 5 years later but I hope you still read comments, because this is the only video that explains well how it works and where The voltage not used by the diode goes
I love your clear explanation of the diode properties in such a practical way. Very well done and so intuitive for learning. Thank you for sharing this video.
10:30 was the light bulb moment for me (or should that be LED moment?) 'The zener diode essentially changes it's Ohm resistance to make sure the voltage drop is the same' Just a variable voltage divider that looks after itself! Thanks for such a clear and thorough video.
Suppose you have a small 6v/1w solar panel and you want to use it to power a 6v/1w motor. Ideally the panel is providing the exact power the motor needs when the sun is out, but it doesn't work in winter or when cloudy. Is it possible to use a capacitor and a zener diode to store the low amounts of energy the panel is providing until it reaches 6v, at which point a pulse of energy is released allowing the motor to run for a moment, the voltage drops, charging happens again and another pulse is released and so on?
Nice clear explanation very good for beginners.... If you use a pass transistor and your zener shunt regulator on the base you create what is known as a power zener capable of much higher stability and current better still use a tl431 in place of the zener lol
Love the vid. There were a few moments I feared you'd skip the part I was interested in (or something you just invoked the interest in), but you always followed through with explanation. I only wish the circuit was more spread out - you have plenty of space on the board - to better see the connections.
Thank you very much for sharing your knowledge on the zener diode. You explain very well and I learned a lot thanks to you on this famous zener diode. I am French and I must recognize that the videos in English are often much more interesting and serious ... on the subject of electronics for beginners. Thanks again !!
I have even seriesed up silicone diodes to create a shunt reg ref in a pinch back in the day to get the psu etc back up and running could even use LEDs if you needed a higher voltage...
Also say you need an obscure voltage say 6.2v and you only have a 7805 on hand you can use a couple of series diodes on the ground pin to lift the ground by two x 600mv diode drops giving the 7805 regulator a new output voltage of 6.2v.......
FRIEND, I have an OLD Lacie d2 Quadra external hard drive that required a 12 volt DC external power supply to run it. I accidentally plugged in, I think it was a 15 or 19 volt DC P.S. INTO IT AND NOW IT WILL NOT TURN ON. CAN YOU TELL ME IF ITS THE ZENER DIODE THAT GOT DAMAGED? I NEED HELP TO FIX IT, IF YOU CAN POINT ME IN THE RIGHT DIRECTION. THANKYOU
why do I have (whatever I do, I tried with different resistors also read the whole data sheet etc.) but any zener diode doesn't regulate almost at all anything in my case. Do I do something wrong? For example for my zener d - 3V and 1000 ohm resistor when I change the voltage in the range of 7 V - 12 V I have completelly different voltages across the zener diode. It supposed to be stable 3 V but I get something like from 2.1 V - 4.5 V depending on what voltage IN is applied just wondering how people get exactly 3 V and stable??!! When I put a small load , even a 350 ohm resistor voltage drops till 1.8 V I don't see any regulated voltage here :( I have two different zener diodes and both are the orignal package (no fake diodes).
Does anyone know can i use a 39V zener on a 42V transformer in order to drop the voltage to 39V for the rest of the circuit , rest of the circuit being LM317 regulator operating in 1-37V (max 2 Amps Current ) , what kind of Zener should it be to drop the voltage for 3V. Thanks
Hi Sidi, you probably already got your answer elsewhere. The gentleman that did this video has an even more basic video about the zener diode where he does mention that the zener is an inefficient voltage regulator and is best suited for low current applications such as supplying a reference voltage to an IC. See ua-cam.com/video/XhQqtdTlRus/v-deo.html
If you google it you can find a wide range of diagrams for regulators. I think some data sheets may have diagrams as well. Try something like lm7805 internal circuit diagram. They all work the same way, though. Just implemented in different ways.
All Zener diode has a power rating of its own. A power rating is how much power that can be dissipated through the device. For instance, a device with power rating of 0.25W can only sustain 0.25W, and it will break the device if the actual power we have on the device is HIGHER than the power rating of it. If there's no resistor placed in the circuit, all the power offered by the power supply will dissipate on the Zener diode. This will destroy the Zener diode. If there's a resistor, some of the current will limited (as stated in this video). Power can be calculated by using P=IV, since the current is reduced when the Voltage supplied remain constant, the total power dissipated on the Zener diode will be reduce too. So, resistor is used to protect the devices in the circuit.
Great instruction, but dude, get a good meter and power/voltage display for your vids! Beginners trying to keep up with allowances for shitty readings will be challenged.

However, i learnt much practical things from you guys, maybe your system is not that bad right ?
Keep it up. You’re one source of real learning for those afflicted with Arduino cancer.

Nice explanation. I have never understood quite how the zener diode works until now. Thanks alot!
Love your explanations!! Eagerly waiting for new videos in Intermediate section.
Love your teaching style. Keep it up !

Easy man. Very easy to understand. Thumb up
thank you so much! these videos are so clear and well explained.
Amazing explanations!
Amazing explanation! Thanks.

You're Welcome :) I have every intention to keep them coming.

Really like this. Good explanations. Not sure why you switched from right-to-left to left-to-right. Atypical.
Fantastic, thanks for your clarity!
Very very helpful and educational. Thank you.
Thank you so much! It helps a lot!!

Fantastic video
Damn ! Amazing explanation dude🔥🔥❤
Thank you
you are very helpful sir!
What is working volatile and clamping voltage? Looked at a zener diode data sheet and did not see zener voltage (Vz).
How did you increase the voltage of your power supply?
Also say you need an obscure voltage say 6.2v and you only have a 7805 on hand you can use a couple of series diodes on the ground pin to lift the ground by two x 600mv diode drops giving the 7805 regulator a new output voltage of 6.2v.......
thank you so much
Amazing Video!
Thank you!
Great Video
Thank You ❤️
adding a diagram circuit by Sketch would be better to understand, otherwise it's a good explaining :D
What happen if i dont give the resistor? (Resistance in the circuit)
What are the things we need to make this Zener diode?
Buy one.
thank u so much!
Can you explain the Resistor connected to the anode of zener diode in reversed bias circuit?
FRIEND, I have an OLD Lacie d2 Quadra external hard drive that required a 12 volt DC external power supply to run it. I accidentally plugged in, I think it was a 15 or 19 volt DC P.S.

Why the voltage drop at 2:12 of the resistor and the normal diode is negative ? Normally they must be positive because 12-0.6=11.4 law of Khirchoff.
Are you using? Lab quality? Instruments?
what is the resistor value you used in the beginning
How about a link to Zener Diode basics?
thanks a lot i appreciated
Hello. What was the value of the resistor you used for the 5V zener diode?
Ruth Mateus check color code ;)
Thank You
what current is flowing when the 5.1 v zenner is used with the resistor ?
God bless!
What application u using sir
Thanks a lot bro
thanks very much
thank you very well video
is it better than a voltage regulator ?

To be very amazing
Can we use it to power an Arduino. Please reply
Whats the name of the software you using. Can you plz tell me

zener diode Dc me bhi Marta hair
Can i connect to zener diode to ac main 230v
great ,, thank you
Is it how the normal voltage regulators are made ? like 5 or 12 volts regulators ? (I am talking about 3 pin regulators)

Awesome...
what zener are you using
I don't see your video on the basic of Zener diodes
i see ..the resistor to limit the current ? but why you want to limit the current ? please thanks

For instance, a device with power rating of 0.25W can only sustain 0.25W, and it will break the device if the actual power we have on the device is HIGHER than the power rating of it.

hi what is the code of diode C30 5T ?
a circuit diagram would be benefitical...i dont know what is connected to what on theat bread board...im no longer psychic.
Great instruction, but dude, get a good meter and power/voltage display for your vids! Beginners trying to keep up with allowances for shitty readings will be challenged.
can i use it as a charger for "6v acid lead battery" ? anyone please tell me
Bilal Bhai no mosfet voltage regulator is better for power supply.
coOL.
Hii
1st
Put 600V on that diode!
อิ.อิ.
Can anyone try this out and give feedback? Get to androidcircuitsolver on google
Ok ok but this is the most useless circuit. You are teaching people most useless examples. You cant even power up 10W LED like this.
i want to give u million subscribers from me but....
