I don't often comment on videos and I'm not one to "subscribe" but had to do both on this one because it's obvious to me that you love to teach and both your visual aids and the order of revelation of your simple explanations are, IMHO, impeccable. VERY WELL DONE, good Sir!

Man, glad you are back. Have seen your different videos about electronics (open collector, microcontrollers). Hope you'll add back them all. Subscribed already

Yours is one of the best electronics tutorial channels on KZfaq. Thanks, subbed.

A fantastic video for the hobbyists, and a great refresher for the professionals. Easy to follow, concise and very well executed. Thanks for sharing this and spending your valuable time creating this content 👍

I have so many questions about the magic of circuits and you answer a few. Thank you.

Thank you so much for making a thorough overview on diodes! :)

WAW!! It was the most beautiful coincidence when I met your channel.❤

Subscriber number 26 here! Just found your channel. Great content - thank you for taking the time to make this video.

Excellent presentation of diode capabilities and common usage.

Nice video. It's interesting to connect a piezoelectric sounder to the output of the infrared receiver. You can hear the pulses and hear differences between different brands of remote!

Very helpful! I sure hope my diodes won't mind being in my circuits now! ✨😃

Your efforts sharing this valuable info are greatly appreciated. ❤

Very good and informative video! Thank You!

Your explanation is amazing. Please make more videos on understanding electronic circuits and with emphasis on what each component does in the circuit.

Respect for you. Your channel helps me to learn about electronics. You have a new subscriber.

A full wave rectumfryer never gets old as an electronics joke. lol

Very very good video. Thanks

Hello, great video, thank you. Good to see you back, I was sad to see you disappeared from youtube! Where are the older vids?

Knowledgeable video.

good presentation. minor nuance though: at about 6:00 in the example of reverse circuit protection you referred to using a schottky diode but the symbol you used was that of zener ;-)

Well done, nice video,thanks for sharing it with us :)

Thanks!

I am learning , that's good.

Thank you so much for excellent presentation and informative videos. I have already subscribed.

Another application is to use the reverse-bias junction capacitance for adjusting the frequency of a tuned circuit - varying the reverse voltage varies the capacitance, which can then change the frequency of an oscillator. Varactor diodes are specialized for this purpose, but the effect can be demonstrated with pretty much any reverse-biased diode.

excellent explanation

Good presentation sir. Keep it up.

Thank you

I love it ❤

Best video man ❤❤❤❤

Thank you again for such a broad explanation and clarity❤

Thanks for sharing subscribed

another fantastic video, I've been making notes.cheers!

Great video friend!! Did you used to have a different channel? I remember watching a video from you about capacitor applications that was extremely informative amd helpful. But the video is no longer available says KZfaq.

Thanks

I like your video, i like the circuit to charge battery

🌺🌹 Excellent 🌺🌹🌺

4 things on my mind to add: 1) LEDs can drop up to 2-4V, depending on its colours! The bigger the band gap, the "colder" the colour and bigger voltage drop! 2) I never heard of flywheeling diode, do you mean flyback or freewheeling? :D 3) I'm missing the explanation of the flyback diode - it's dropping that peak voltage because it allows the coil to "decharge" through itself (to absorb the inductive current kickback), making a nice peak current "circle" flow between the diode and the coil, instead of your circuitry. 4) I'm surprised you didn't mention opto-isolators alongside with LED transmission devices, those are my favorite type of power protection devices!

عالی بود استاد

I really enjoyed this video and have now subscribed. One question though - Re the induction motors, why do you usually see a capacitor across the terminals and not a diode? Or do they serve different purposes?

I did not know S and Z rule and have worked in electronics for many years, thanks

Sir, I am from Bangladesh 🇧🇩. I recently search your channel but could not find. Today Got you❤️

Hi and thx for your effort. I wish someone would make a video on how to find/calculate value etc for real life situations for us ignorant enthusiasts. Let me explain. I am using lots of buck converters - boosters and lithium solar chargers. I use bear modules for cost and flexubility. In their instructions are mentioning not to reverse polarity and put a diode etc. How do I find which diode? how do I calculate values? I have clamp meter and accurate multimeter. No more fancy bench instruments. I do not want to become an electrinics engineer just solve everyday little problems in laymans terms. Any help or direction much welcomed. TNX

Wonderful tutorial! As you rightly mentioned that zener diode can be used to protect the circuit from over over-voltage, can it protect an ac voltage? Can it take care of under-voltage?

nice video,, can you make a video about replacing diode on solar panel?

Awesome video. New subscriber here.. Please also make video discussing applications of inductors.

How do you read the code printed on zener diode should you not be able to get the data sheet for the diode? Would appreciate it for the assistance as I feel that all my research to my question is leading to no answer and thus I hope that you will be able to assist me. You're explaining on components and examples are the best that i have seen and even advise my colleagues to watch and subscribe to your channel.

nice channel!

6:02 good explained

At 7.42, you mentioned a video on charging a backup battery setup, and I am most keen to see that, but I can't find it on KZfaq . Can you direct me to that one please? Great videos btw.

Greattt😅

Make similar video for coil inductor

So I can use a ZENER diode to block current in a circuit when the voltage is below the zener diode voltage?

Sir i have being following your channel, but i can't find Your old channel anymore what's wrong with it, i do love your videos

radja + lep, just saying, can you do the driver?

I have a basic question I was hoping you could answer. Normally, a resistor is used along with the diode to limit current. However, when used as a rectifying diode bridge, I normally do not see any resistors being used to limit the current. So my question is, in that case, what limits the current? Is it only because they are high current diodes and therefore don't require any external current limiting? Thanks!

Good evening sir... Very nice video.... What happened with your other channel... I really missed u and your video... Lot of ❤ from odisha, India

Hi i wanted to know that how circuits are designed. How do engineers know where to put a capacitor, resistor or inductor. I think its an advanced topic but a simple explanation will do enough.

There is another way to reverse polarity protect with a diode, that's by placing a regular diode in reverse bias across the power input so long as your power source is fused. Connecting the power backwards would pop the fuse before the diode burned.

Anyone know what would be oscilloscope banditech/samples if I would like to see and keep testing (able to see what what is happening) these at home with these diodes (and possibly some NAND /transistors) ? On this video looks like it is 100Mhz Oscilloscope, that would be pricy for just learning and small tests. Thank you

what happened to the old channel? I saw all your videos long time ago but here it looks reuploaded! is this a new channel? any way I subscribed and waiting for you to Explain more electronics and more concepts good job my friend

I would prefer you show me how to build 8 useful devices with diodes.

hehe hmm, I think the zener diode might have saved my arduino from literally smoking the other night =D

Sir, I got your feedback on the question that I raised. I commend you for it. You used 1N4148 as a flyback diode in an indictive circuit instead of a power diode such as 1N4007, Why? I think that 1N4148 is a signal diode and used in a circuit that requires high switching speeds. Please, refer me to your videos on Operational Amplifier and how one can use it to compare AC voltages. Thanks.

قربون لهجت برم من 🤩😘

Mr. Exist applications to switch his lasers, maybes calls Spectogram or Spectrum, something with Hz, I almost put him down long times ago. He want to kill himself, gives for us that he want to stop. Thank You.

3:32 that's a bridge rectifier

Solar cell is a diode. If you put power into solar cell it will emit deep red light visible in camera. Diode can be used to protect relay contracts from REMF from a heavy DC inductive load when contracts open. The diode absorbs the energy that produces momentary arc in relay contracts.

I'm new to this. I'm an electriian. But I have a question

Is this your new channel. What happened to your older videos

I believe, that these components have a complete computer inside, especially the SMD types. To control the computer, first it must be installed into a device. When you experiment with charging, your diode become removed from its default blacklist, and starts its normal operation, for example removing the memory effect from batteries. Same with SMD resistors, but when you destroy one, there is no computer circuit inside. So the component is on blacklist due to radiation, and the component’s memory effect status causes its default regional blacklist.

Put the yappy dog in another room lol 👍

Thanks for the video. Can you please in the future remove the "bleep" sound? Hurts my head.

a diode is the best invention ever, Even betterthan the light bulb. (even though they were origionaly a light bulb)

we used to get potable 12" tvs from the tip and change the diode then sell them i was only 10 made a fortune in the 70s from caravaners that had put the leads wrong way around

Is there a specific way to determine which voltage and amperage of a diode I would need for a a circuit. Thanks for the video btw. I now know I need Schottky and Zenner diodes for my applications. I'm trying to make circuits for multiple power supplies and want to use the diodes properly. So for example a wall 12v power supply, a solar panel setup , and separating different chemistries of battery banks for charging and discharging in the same circuit along with a capacitor bank for large voltage spikes from motors. I like a challenge I guess. I literally want my Off grid setup to have as many options as possible for stabilities sake. Getting into solar has revitalized my interest in making circuits. Especially when DC to DC power circuit adapters isn't as standardized for the home as it should be. I see a business opportunity to make it more plug and play. The current environment is having the end user play with naked circuits to get what they need. Which is frustrating when running everything from DC in a home on solar. The closest thing to plug and play is car auxiliary plugs and USB 3 and USB type C but it limits what can be done to 12v and 5v. In a DC only setup you sometimes need 24v and 48v devices. I'm aware of buck and step up converters but they are not plug and play. Companies simply do not supply DC only adapters for their devices if its possible to do so which creates the headache I'm in, but I do spot the opportunity to have a business that they can point to for the purpose, and trust that it will run their devices safely for the end user. I'm working out a plan for it. Maybe one day you will see the converter option on power brick inverters for your devices. 🤷‍♂ All I know is why did it not happen sooner. Its even an advantage for Survival and Emergency situations because DC is the last power source to work. Even in a pinch. Thank you for listening to my TED talk lol.

The only component I think of as “simple” is the wire. And even that requires a bit of thinking when the gauge becomes crucial in the application. 😢

You can also use silicon diodes als switches for low voltage ac signals. As long as the ac signal is lower than the forward voltage the signal is blocked. When you now add a dc voltage to the ac signal, which is higher than the forward voltage, the ac voltage will appear behind the diode on top of the dc voltage. Using 2 capacitors before and after the diode you can switch the ac signal on and off. You can also use a full wave recitifier to switch between a current sink to ground and a current source from the positive supply voltage a point in your circuit whos voltage is between positive supply voltage and ground. you just need to connect one of the ac inputs to your circuit point and the other between ground or positive supply voltage. The current source and sink are connected to the dc outputs of the rectifier. In this way you can make a 555 astable multivibrator whos output switches the current source and sink to the capacitor point which gives a precise linear voltage ramp, which can control other circuits (for instance a vc oscillator or a vc PWM generator).

I create a node on common positive side, using diode to merge them using a full bridge diode, in my country Indonesia its actually cheaper to buy high amps diode by using full bridge rectifier 😂

a diode can also be used to make an AM radio

Very strange things happens at time 3:38-3:39 . Suddenly the circuit transformed to something quite different that it was a moment ago, but there was a perfect oscillogram. I have an idea what difficulties author experienced . Likely it was the ground which is common for both channels. It is very sad that the author didn't clearly show how he resolved that.
