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

[@makemoneyonline7502]

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.

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

[@Ivanzrer]

Flashbacks to the first time I saw a zener diode on a schematic. This was in a highschool electronics class, in what I guess would equate to junior year in the united states. It was however in the "Elektrofag" (Electro-subject) line of the school system. We had basically not been given any education on what anything was at that point, since it was pretty early on in the year, and the teacher drew this schematic for a rectifier. I knew a little bit, so I managed to piece together how it worked, except for the diode. I had a look at the diode and thought to myself "thats a funky diode, I wonder whats different about it" and I asked the teacher as such. He tells me "oh thats a Zener diode" and wrote that on the board. I ended up having to ask this teacher about it several times throughout the year, and the best explanation I could get was "The voltage across it is constant" Needless to say, those who joined that line of school planning to do something with electronics (myself included) were so demotivated by the utter confusion those classes were, that practically all of us ended up not persuing that.

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

[@daikatarokamegawa542]

Honest question... how? I mean... seriously, I don't see LEDs acting in any way like a Zener. They have a very wide forward voltage range, so you can't realiably put several of them in series, and get an accurate Vout, unlike Zeners that have specific Zener voltages and don't deviate much from there. For less money than you buy enough LEDs to match typical Zener diode voltage, like 12v, you buy a 12v Zener diode, a 547 NPN transistor, a resistor and an LED, that indicates the Zener voltage has been exceeded, and have a much more accurate reading.

[@opera5714]

@@daikatarokamegawa542 That is a very narrow view of electronics. A good designer uses every available technique to shave fractions of a penny off a design. A LED can be very useful as a low voltage reference, level translator or voltage offset. I can think of a number of ways a single LED could be used to make an adjustable 12V power supply. Stringing a bunch in series is a pretty absurd example.

[@daikatarokamegawa542]

@@opera5714 That's why I said, how exactly?

[@kennmossman8701]

Well a LED does have a significant Vf but that varies by current and temperature so it is not a great substitute. Additionally a LED has a max current and low reverse voltage. It certainly is NOT a voltage reference. More-ever the 'knee' is not nearly as sharp as with a Zener. As well to get say a 9V output you need 3 LEDs (Vf of 3V) which takes up space. I have used LEDs as a weak means of getting a more stable voltage but the actual voltage (over current, temperature, etc was not important.

Saw this video on the KZbin main panel and it brought back memories of a fraught Saturday in the Lab. On the Friday just before knocking off time I was given a request from the other engineers to look at a D75 Oscilloscope. I was on my way over to the racks to sort out something for overtime tomorrow Saturday. OK I picked up the D75 and heard Chris say "Its in the pre amp trigger somewhere". That was NOT good news ! Timebase faults can be so and so's. I was eyeing up a D67 which I loved to work on, favourite was the Tektronix 453 though. I sort it out on the bench, take the covers off, get the service manual off the rack and an extender cable to timebase plugin. D75s are flat rack mounted or desk on the legs. Party Friday night, drive in next without a single memory of the journey in barely able to see let alone walk ! I stagger to my bench in the thought of what is to come. Nothing gets done for at least 20 mins ! So hung over ! So I start, find a 5.7V Zener reading 5.85 ! Looking at the location proved why others couldn't find it ! 1.5 hours to remove the board and out comes the zener onto the Telequipment CT(906?) Curve Tracer. Get to 5.7V ok the run up the transfer characteristic to see 1/3rd of the way down the trace it splits into strands like a split hair, no curly bits. Whaaat? Quickly i replace the zener, make good the board, you couldn't tell anyone had been there, after two years on the bench my soldering was very neat. Was a bricklayer two years before and before that a tank gunner. Flashed it up and TaDa ! there was the trace trigering like a good'n. I walked slowly over to get a cup of coffee. My hangover completely diappeared on seeing 5.85V, then a smile at the successful trace. The comments soon quietened down as I was collecting my coffee "Havent you fixed it yet Tony ?" A smile was the reply, several engineers rushing over to see the curve tracer and the scope with its clothes on and working fine. "Very well done Tony" Ian said ! Struth I've seen him say "Hmm OK" to one of the other engineers after a three day struggle to find an intermittent (Salmon Pink) precision resistor, very rare ! Three weeks later my pay was raised to the other engineers from trainee's pay. Will never forget that. So far no one has seen that, so maybe I havent been asking the right people, but all were repair and calibration engineers. the most rewarding and exciting experience of my life, I loved it. Analogue component fault finding is the best !

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?

[@aodhmacraynall8932]

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.

[@rossgee2950]

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.

[@MrCuddlyable3]

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.

[@NesaSimonDavid]

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?

[@Mateyhv1]

Very good question indeed!

[@xXBR4D3NXx]

Hope this gets answered.

[@Memo-windowsBlogspot]

he didnt say at 2:39 it was 12v but when increase the volt 51v he says exceeded at 3:05 ,,and the best work put volt at 24v in the dc supply

[@badrunna-im]

Before the breakdown there was no current to provide the voltage drop, so it would have been equal to the supply voltage at some point . After breakdown, the diode still conducts in reverse even if the applied voltage is lower than the breakdown voltage, as the breakdown is generally irreversible.

[@technologyrethinked]

zener diode is eating 0.1 volts, it's called voltage drop. is like sending dc current at a specific voltaje through a long vable. when measuring the voltage at the end will be lower than what it began with

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?

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.
