What is a Zener Diode? - Electronics Basics 15 

For some reason this english channel explained the Z-diod better than any german one I could find

its the simplest and easiest explanation i have found for zener diode ...good job

You know, it's illegal for you to explain an electronics concept well and not be Indian

An educator's point of view explanation, very clear, and informative

thanks for such a simplified explanation:)

The app is called EveryCircuit. And this is the best video I' ve ever seen. I finally understand Zener Diode.

best explanation of how a Zener diode works. I have checked many other sites but this is the best.

Thanks, helped me understand why a Zener Diode was in the wiring of an old cruise control set up on a car.

Hello Many thnks for thid vidéo. The role of a ZENER is essentiel in our circuits. Thanks again

after searching and searching and....for a good explanation about how Zener really works, this video was far away the best one! thank you very much! im totally clarified!

Little summary of this video : Diodes allow current to flow in only one direction. If you were to reverse-biased (change the direction) the diode, the current will not flow through the circuit until the "Zener Voltage" has been exceeded. As it happens, the voltage of the power supply is at 5volt. He moved the voltage to 10.8V, like that the "Zener Voltage" has been exceeded and the current can flow through the circuit. Zener diodes can be very useful for : creating voltage references, shunt voltage regulator and over voltage protections circuit. When you were to increase the voltage of the power supply to 51V and measuring the voltage throughout the zener diode with the help of a voltmeter, you'll notice that the voltmeter measured a voltage of approximately 10 volt and therefore you created a 10 volt voltage regulator.

An excellent explanation of how a zener diode works. Now, I understand what this type of diode does!

Your explanation is awesome ...thanks

so eloquently explained ,having watched and read others, was not able to grasp the subject, but your teaching is instant to grasp.THANKS,made my life very very easy,too good..keep it up

Great Vlog! very simple but very easily understandable, I'm new to your channel but I'm fascinated by how you create learning materials, pls. continue creating next ones about electronics..

this is a perfectly organised presentation. Thank you for taking your time into helping in the best way possible

Great videos. I'm doing more or less independent study at a technical college in electronics; it's a pretty sweet deal as long as I keep up with the reading, the homeworks and the lab work. But, I find myself wishing I had more instruction in some of the very basics and even just a different narrative than offered in a text (Boylestad). Your video fill that need. They help keep me on the straight and narrow as far as focusing on the topics and I cannot stand listening to those effin curry-chompers on some other channels. Keep up the videos. You've got my vote.

Nice to have such a simple and straight to the point explanation. The video demo was great too.

I really appreciate your videos, but.. the elephant in the room is the resistor that is dropping the voltage in the circuit to 10.1V. The video implies that the zener diode is responsible for this voltage regulation. It clearly is not. It is simply a checkpoint in the circuit that blocks flow in the event of a voltage drop below that imposed by the resistor.

At video 2.23 the voltage difference across the zener diode ( 9.94v) is less than its breakdown voltage.(10v) How does the zener diode allow the current to flow thru the circuit?

This is the best explanation of Zener diode I found!! THANK YOU! I definitely subbed!

Beautifully explained. Many thanks

You made it simple and easy to understand, great job!

which software are you using for this stimulation ? great video btw :)

liked, great info. keep up the good work!

Take a shot whenever you hear 'diode'

explained more better than my phy sir

Thanks a lot. Very simple and useful presentation of a Zener diode.

For the people who ask for the simulator : everycircuit.com Good luck everyone

I recommend this channel to other beginners ❤

you are awesome sir, i luv the style of your teaching very thankful preparing for my final exam with your vids

Most don't realize it, but a LED makes a pretty good zener and can act as an indicator at the same time. I use them often that way when a TL431 is driving a transistor or opto isolator. A standard red LED is approximately 1.7V

thanks for that video demonstration of how zener diode works in reverse biased condition. Other wise it was difficult for me to even understand what is reverse biased, forward biased.

Renez diods pass current the opposite way depending on the negative base bias. As long as you have a modulated negative power supply giving no more than 153.6V reverse EMF. They work best in unstablized A/C high current motors. The motor industry were to use this method of voltage control in hybrid cars but found they were unstable in resistance due to vibrations while moving.

So it prevents current from passing it, but should a current exceed its voltage capacity, it will keep the voltage to its capacity stopping the circuit from having too much voltage. Handy little thing, isn’t it?

What the? But how the? Huh? that's mad. Great video, now I have to watch the next one just to get my head around what just happened.

Great illustration in simple words.

Great video. It helps with my electrical engineering studies. Thank you.

I like how you explain things clearly and simply!

I remember that a reverse-bias Zener Diode was used on some early (1970's) Triumph Motorcycles. This Zener Diode was placed under the Headlamp, and had alloy Cooling Fins. This limited the voltage/current to the on-board 12V battery, and dumped all of the output from the Alternator to Earth when the battery attained 12 volts (and fully charged). Probably would have been a better idea to utilise the excess voltage from the Alternator to power Day Running Lights in hindsight! I really liked your simple explanation of the zener diode and lots of potential uses for this component.

Very well explained visually and easy to understand commentary. Thank you very much and looking forward to watching more of your videos.

perfect video, thanks a lot. can you tell me what is this application?

Simple and Easy to understand, you work is just great ...

U interpreted the concept within 3 minutes and some couldn't do in even 30 minutes. BTW what software u used ?

Hey dear friend it was very useful for me thanks a lot for your sharing

thanks man this video has helped me a lot in understanding the concept

this video = (short time )+( easy to understand the concept )

Brother you're amazing.

Very food video!!! What is the application he is using to demonstrate? Please

was looking forward for the breakdown explanation >>

I can't find Previous video on diodes . Pls help

稽納二極體看起來反向時需達一定電壓才能導通，導通後， 即便調大來源電壓，此二極體仍能維持穩定電壓。

Simple great explanation !!!!!! Good job!!!

Thanks from India 🇮🇳🇮🇳🇮🇳

It is really good to understand this topic Trimandiously ever....

The best illustration of a Zener I have seen but you need to add the resistor and why it is there otherwise magic smoke, so joined your channel thanks

Awesome video, informative and clear. But I wanted to ask, what program were you using for this demonstration?

How about the current flow? Although voltage is not too high, but too high current will also damage the LED (for example, if LED as the load)

For years I've been asking my teacher about this, all i get is "its the same as normal diode"

Hello, What is the application you are using for simulation?

Amazing breakdown. amazing. I applause thee.

I always use a zener across the pins on an ADC, if there's any part of the circuit above the procesdor's supply voltage. Way easier than replacing the chip if something shorts or blows 🙂👍

on what software are you making these circuits on??? i am currently using multisim. kindly tell me it's name

Zener are these two pins current eater diode semiconductors notorious for their waste energy cosumption until to get the desired voltage.And the less the current that flows through their load then higher is the current that flows through the zener itself.So the amount of power consuption of any zener regulator is exactly the same with or without any load being connected.

Excellent explanation

Wow it's simple and clear to understand. Thank you

Nice to the point explanation

Thank you🤗

Excelent, woul like to see the second part when you explain how to calculate the limitint resistor, thanks !

Very nicely explained. Thank you for your knowledgeable video. Have subscribed your channel.

please what program do you use on this video?

it is marvelous how you make things easier hat off

Superb explanation! Thanks

Brilliant explanation. Thank you so much

Best ever explaination

That's awesome I need more

great described .i suggest more episode about another diodes.! thanks!!

I didn't understand one of the examples in this video... at 2:39, he says that the zener diode's breakdown voltage has been exceeded, but in fact it hasn't. The battery is providing 12 volts, but the resistor reduces the voltage to below 10 volts. So how did the zener diode breakdown when the voltage is only 9.9 volts?

0:38 Applying 5V forward bias to a diode without limiting resistor is a reckless bad start. The current will be high (you are seeing over 4 amps which will vary with diode) and burn out a common small diode.

What are you using for software in this video? It looks like it would be very helpful for someone learning electronics.

ZENER DIODE-zener diode is just lyk any other regular diode that allows current to pass throught it,but when it is reversed it does not allow any current to pass through until it reaches a particular voltage known as zener breakdown voltage.once it reaches that voltage it allows current to pass through it.

what voltage would a ZD6 zener diode be?

Super easy to understand. Except is there any point at which the Zener Diode gets destroyed? Or heats up?

I've always heard of the zener diode in my field of work but never actually sat down to realize how useful it is in electronics

Very well explained. Thank you so much sir.

Nice Explained Sir. Sir please make more videos on Basic Electronics

Is that video about zener diode voltage regulators coming soon?

simply explained ❤

Which software did you use for simulation

I just used this to double check my understanding because I have some zener diodes that start transmitting energy far before their breakdown voltage. Looks like they are just crap!

Awesome sir what aa way u teached great sir biggest fannn

Hey man, I know you stopped making videos, but they're great. I think people want you back. I know I do.
