whistling is annoying
Like a hillbilly missing a tooth.
Yes more disturbance.... irritating
😂
I already hate him for putting this out there
Quick question: are mosfets marked always with a Q in a pcb or can the get anothet letter? As I've come across an U transistor in a circuit which should be a mosfet itself
*can they
In some motherboard can marked U
hello, I followed your explanations carefully but I always have a double reading on the 3-leg smd mosfets, so it is impossible to determine which channel it is pnp or npn since when I change the probes it also shows me a reading on the same legs I'm a little lost I expected that there is only reading in one direction as you have shown, except that all the mosfets that I tested with 2 different multimeters do exactly that the same things double reading, on the same type of mosfets as in your videos and on functional and non-functional cards, I do not understand the 2 readings are satisfactory and displays good resistance on both sides impossible to know which channel is it, are there any exceptions? I do not understand anything anymore. thank you to enlighten me.
Same here...........
I guess the best way to test those transitions is to remove them from the board and test. If not u sometimes experience most of those readings or results
new skill is added to my career.thanks sir
Thanks
if it beeps with a low reading does that mean your mosfet is short circuited and considered a bad mosfet? I checked all mosfets and every mosfet beeped when i check it with a multimeter with a low reading?
Most complete video for mosfets - thank you! But I was told that a way to remember what NPN means, is to think of the letters standing for: Never Pointing iNward but the arrows in your picture of the NPN mosfet shows the arrow pointing from the source to the gate - inward. I was also told to remember PNP as meaning: Pointing iNwards Perpetually. So, what is right and what is wrong? Please let me know, I want to learn. Thank you
Thanks for the info!
@@electronicsrepairbasics_erb Ok, but you haven’t answered my question.
I think you are right. The image at 5:57 is rather N Channel mosfet which is PNP.
Best explanation of the mosfits on UA-cam! 👏
Great work
Thanks
Why is the reference showing "U" for mosfets instead of "Q"?
In the other video you said U is the reference for intergrated circuit
Please I have a laptop and when I test all the MOSFET around the processor with a multimeter set on diode I discovered that it reads from the gate to source, gate to drain and source to drain with all high recistance
I'm see a similar voltage reading between source and drain regardless of positive/negative lead orientation. Is this an indication of a shorted diode?
Sir , your explanations confuse me . In my motherboard , 4 8-pins mosfets near the CPU give continuity between source and drain even if I reverse the probes , but I have no continuity between gate and source . There is another serie of mosfets on the same motherboard, near the power socket , they give reading between source and drain in both way , but no continuity . among them are two 8-pins mosfets where I get no continuity , no reading between the 4 pins of the drain
Remove the CPU and the short will disappear
@@electronicsrepairbasics_erb you were right , the short disappear even on the back side of the PCB
Love the voise manipulation lol spooky tech.
Merci pour votre explication aussi bien explique bravo a vous merci pour la video
Thank you
Thank you!! that is what i was looking in the internet, the practical electronic. you are the best!!
Wow, thanks!
The world's best teacher thanks sir
You did a excellent job teaching and explaining but please edit the audio, some simple planning and audio peak monitoring. Audio can make or break the experience. Apologies for unsolicited feedback
i am testing a mosfet that is an TPCA8A10-H . I believe it is a Schottky barrier . between source and drain i am getting 22mA's .022. seems low to me. there are several, they all get the same. are they good? on the data sheet is this the forward voltage?
his teaching is very clear, i learn many things from him..but sometime i could not catch up nad understand some things as i do not understand..

I have the same 4-pin Mosfet on my pcb. I checked source and drain. The number jumped to 800 and was still climbing above 900 and then it went to 0L. I think it's bad, isn't it?
Thanks your video, I managed to find out the mosfet FHP100N07 was the fault. Swapped out parts from donor board and my e-scooter is now working
I keep seeing a fake elon musk add on your page... Why am I seeing 4 ads in a 12 minute video.
Great video as allways well explained 👍could you tell me how to read the markings on smd mosfet to buy replacement, as been repairing a motherboard and have n channel that I need to replace, but have no idea how to order or get a replacement many thanks in advance
Peace be upon you. Please, any information about this electronic piece. Is it two Schottky or Mosfet? For information, it is on the LED TV panel C2 OM thank you
Bro just have the dentist fix your teeth
Thank you Bro
It would be also awesome if you showd how the shorted or bad mosfet reacts :)
this is great chanel i hope you focus on desktop motherboard
Sir how we can test Lm2592hv regulator with multimeter
Very good video. Thank you very much. 😊❤
You are so good at explaining this!!
Well explain video! Could you pls show us how to identify sound, keyboard e.t.c ic
Hi,
The reply is in my channel:
Video title "Laptop motherboard components names & functions explained"
Regards,
very good
Thank you! Cheers!
Good job
Thanks
I really appreciate the examples and the readings along with explanation of them.
Glad it was helpful!
I have a faulty Lenovo all in one 330 computer, it doesn't switch on . I got it dissasembled , I tried to check the components , and I noticed that when I pluged the power supply , a 8 pins mosfet near the power jack/socket was getting hot . I checked the mostfet , the drain , the source and the gate are good . Theres a ceramic smd capacitor 1cm away from the Mosfet , and when I check this capacitor in continuity mode theres' no reading , "I " is displayed , even when I reverse the probres , what could ne the problem ?
Check all components near to that hot mosfet you will find the failed components, usualy it can be a diode or a mosfet.
Hi. am assuming that you are referring to the first mosfet after the charging port. First check if you have a 19. 5 voltage on the output of the first and second mosfet... If you dont have output voltage after the firstmosfets, try replacing that mosfet thats getting hot🔥. Let me know....
Best explanation of the mosfits on UA-cam! 😍😍
Wow, thank you!
I like ore your video
This video is realy helpfull thank you 👍🏻
So glad!
The best Channel. Thank you for teaching...
Glad you think so!
With some practice, I think I will finally get MOSFETs thanks to your video. Thx!
thx
What you are saying...
??
Thanks for good information
So nice of you
u r the best thx
You're very welcome! Thank you
I think in this video, a "good MOSFET" is a DEPLETION MODE MOSFET vs an ENHANCED MODE MOSFET. Correct?
In looking further, I see that your ENHANCED MODE MOSFET has a diode between drain and source allowing flow from source to drain. Also, that PCB can confuse you as you watch because MOSFETs 1 & 4 have pin 1 top left, and 2 & 3 have pin 1 bottom right.
thanks a lot sir
So nice of you
tx sir
All the best
Thanks you
Thank you too!
great video is useful
Thank you.
Thank you.
You're welcome!
Well explained 🙌
Glad it was helpful!
I really hate finding a good video that explains no decent stuff about components And it has to be. Watered down with a dude with a deep voice who Has a whistle to everything that he says. Like the old perverted dude on Family Guy kind of Annoying
I have looked everywhere do you know where I can find. 3 pin
GO65N07. AOL05NSS1A Mosfit? Thanks.
Hi,
Do you check AMAZON Platform.
@@electronicsrepairbasics_erb I did find on the top number is G065N07 but the bottom number on the mosfit is not the same number, I'm not sure if the bottom number on a mosfit is a Batch number or a nu.ber that is to indicate to the company what voltage it is good for. Hope this makes sense thank you for responding
