Very useful information, I realy felt heard to find out the voltage value since the diode is very small and couldn't find the value printed there. This is a good alternative method to find unknown owner diode value. Very smart information. Thanks for this video. By, Paul
Thank you, very informative video.I went ahead and tested with zener diode that i knew the value 3.3 volt and my power supply.there is one issue the diode does not stabilise at 3.3 volt when i go up on power supply up to 30 volt the diode also goes as high as 4 volt too. how can i conclude the exact value ?cause we have 3.3 diode, 3.7 and 3.9 too.thank you

I have a door chime that stopped working. There's 3 zener diodes that all beep when I test for continuity. Does that mean they're all bad? I didn't take them out of circuit. There's 3 other regular diodes (black with silver stripe) and they don't beep when checking with continuity tester
@@HaseebElectronics ok so I took one of the 3 zener diodes out completely. It measures 0.002 each way in diode mode and beeps positive for continuity. So they're bad correct? Thanks a million!! Ps. This door chime has no step down transformer so I assume the diodes and big capacitor does that. Also, the pcb was darkened near the 3 diodes....looks like it got hot on the pcb in that area
Always brilliant with your explanation and your informative videos. My question is when we make a circuit in which we use a ZD do we put any resistor value or we should apply OHMS law (formula).? Thank u
if no part number or code visible, in that case we have to find the service manual or circuit diagram for the circuit. or we have to look for similar circuit or there is another way to analyze the circuit and reverse engineering, but in that case it will an assessment
Like me I had to get a 2nd same board to check unless diode has markings you can read. Otherwise it's an educated guess I guess. For example if it sits next to an IC that requires 5v it may be a 5v zener.

Nice
gotta respect when you need something explained masterfully the only person with the true answer is tired indian man on youtube
thanks so much haseeb
I often fall this type of problem... But what you have teach us today is really very simple and effective ... Thank you. ❤️ From Bangladesh..
My pleasure 😊
its next part is coming to understand the zener
Your videos seems like, a student learn in persons apearance with professor in classroom.
Amazing Haseeb.

Thanks very nice information about zener diode. جزاک اللہ خیرا
Lk 4 brother 👍👍👍
Fantastic, Mr Haseeb.
thanks a lot
Explanation with practical is awesome,nice video 👍
thanks a lot
Best sharing your good work
Many many thanks
Sir, apake video bahut useful hai. Sir apase ek request hai ki ek video computer ups pe banye.
thank you sir this will help me a lot
Very informative video. helpful sharing. Jazak Allah please stay connected
Excellent job dear friend!!!
Mashallah welldone bhai informative vidio wajeeha lv

Very useful information Sir Thanks for sharing this knowledge to us
So nice of you
Simply excellent! Thank you.
i am thankful
Very good demonstration. Thanks
Hi friend thanks for showing an easier way to test a zener diode
You are welcome
Thank you very much brother for this information
Thank you sir 🙏🙏
Nice information
Salaam Janab Bhai Saab
thanks a lot dear brother
as always very nice sharing

Its was very useful video🤗
many many thanks
very helpful video 👍 biggg likkkk 93 stay blessed 👈
I did it, it works great!
wow
awesome
thanks for your feedback
good explanation
Thanks and welcome
Sixty fifth lk. Bhai 🙏sry,i am not seeing your videos😔regularly .

Thanks for video🔥❤️
Brilliant. Thank you
You're very welcome!
Great information. Thank you.
Thank you Sir,

I have a door chime that stopped working. There's 3 zener diodes that all beep when I test for continuity. Does that mean they're all bad?
I didn't take them out of circuit.
There's 3 other regular diodes (black with silver stripe) and they don't beep when checking with continuity tester
it is best practice to open one end of the zener. in some conditions it gives false beep due to parallel components
@@HaseebElectronics Thanks...thats what i suspected.
@@HaseebElectronics ok so I took one of the 3 zener diodes out completely. It measures 0.002 each way in diode mode and beeps positive for continuity.
So they're bad correct?
Thanks a million!!

Good Video My Friend!
Thank you very much!
@@HaseebElectronics Your Welcome Buddy!
Thank you sir for your information but what if a zener diode got burnt in a how can you know the value
Always brilliant with your explanation and your informative videos. My question is when we make a circuit in which we use a ZD do we put any resistor value or we should apply OHMS law (formula).? Thank u
video number is 397 on this topic
and the next video is also on Same topic
and that will in full details for zener
Nicely done. Thanks
Thank you very much can you explain how to chek the mosfset by using multimeeter because some one saying it is not possible thank you very much
This zener that you test is ok but What about a die zener when its short ؟؟
if no part number or code visible, in that case we have to find the service manual or circuit diagram for the circuit. or we have to look for similar circuit
or there is another way to analyze the circuit and reverse engineering, but in that case it will an assessment
Dear, thanks, pls advice how to know the voltage of faulty smd zener
Sir, how will we find short ( unserviceable) zener value
Nice video
thanks a lot dear brother
Golden Like!
Nice one
best regards and special thanks
Thumbs up done
it is my pleasure
Sir can we test the zenervoltage by using led tester?
i think no. we have need to test with multimeter
@@HaseebElectronics ok sir :-)
Assalamalikum sir
wa alaikum salaam dear brother
Conceptual learning on this channel
best regards. I always try to explain it some easy ways
It's awesome
best regards and special thanks
what if the diode is shorted or dead?
Like me I had to get a 2nd same board to check unless diode has markings you can read. Otherwise it's an educated guess I guess. For example if it sits next to an IC that requires 5v it may be a 5v zener.
Sir capacitor divider ki bare main video bano
👌👌👌👍
best regards
Pls make video 3kva online ups
ok dear i will try to arrange for it
please accept my best regards
وعليكم السلام جميل جدا
best regards and special thanks
I didn't understand this video lesson, I always thought that a diode the positive always went to the anode and the negative to the cathode.
