Glad it was helpful!

[@kabandajamir9844]

The world's best teacher thanks sir

[@eniltoh]

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

[@surgingcircuits6955]

With some practice, I think I will finally get MOSFETs thanks to your video. Thx!

[@helmuthrendl6560]

The best Channel. Thank you for teaching...

You're very welcome! Thank you

[@maxwarfield6699]

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

[@electronicsrepairbasics_erb]

Thanks for the info!

[@maxwarfield6699]

@@electronicsrepairbasics_erb Ok, but you haven’t answered my question.

[@dzabakwesi2213]

I think you are right. The image at 5:57 is rather N Channel mosfet which is PNP.

[@mustafa75ful]

thx

[@remancupido5323]

thanks a lot sir

[@electronicsrepairbasics_erb]

So nice of you

[@haydenm315]

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?

[@Steadyeddie100]

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

[@kakysamir9681]

Thanks you

[@electronicsrepairbasics_erb]

Thank you too!

[@NerdThingsAndMore]

Thanks

[@crazydwarfer]

It would be also awesome if you showd how the shorted or bad mosfet reacts :)

[@user-qh5kb7rv7o]

I like ore your video

[@computerguy7213]

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?

[@chol5808]

Love the voise manipulation lol spooky tech.

[@said-nana70]

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

[@jmenezdesigns2945]

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

[@moonshine3657]

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?

[@knowledgetreasure-1523]

this is great chanel i hope you focus on desktop motherboard

[@mustaphayahaya4393]

Well explain video! Could you pls show us how to identify sound, keyboard e.t.c ic

[@electronicsrepairbasics_erb]

Hi, The reply is in my channel: Video title "Laptop motherboard components names & functions explained" Regards,

[@nabenf7727]

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.

[@digigarb]

Same here...........

[@kaveyakubu4940]

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

[@GetachewAdise]

tx sir

[@electronicsrepairbasics_erb]

All the best

[@ElectricalEngineering-sx7fd]

Good job

[@electronicsrepairbasics_erb]

[@etiennewilson3813]

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

[@jozsiolah1435]

Found in power banks and cigarette chargers. They can be programmed by high end phones, by plugging it in while the phone is off. It turns on delta voltage charging.

[@PolyCube71]

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?

[@arslan881]

Sir how we can test Lm2592hv regulator with multimeter

[@KalaleMuneku-uk4pt]

Why is the reference showing "U" for mosfets instead of "Q"? In the other video you said U is the reference for intergrated circuit

[@lucabarattini3184]

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

[@lucabarattini3184]

*can they

[@electronicsrepairbasics_erb]

In some motherboard can marked U

[@tunkunrunk]

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 ?

[@electronicsrepairbasics_erb]

Check all components near to that hot mosfet you will find the failed components, usualy it can be a diode or a mosfet.

[@IS-77]

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....

[@tunkunrunk]

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

[@electronicsrepairbasics_erb]

Remove the CPU and the short will disappear

[@tunkunrunk]

@@electronicsrepairbasics_erb you were right , the short disappear even on the back side of the PCB

[@surgingcircuits6955]

I think in this video, a "good MOSFET" is a DEPLETION MODE MOSFET vs an ENHANCED MODE MOSFET. Correct?

[@surgingcircuits6955]

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.

[@theebikeguy3852]

I have looked everywhere do you know where I can find. 3 pin GO65N07. AOL05NSS1A Mosfit? Thanks.

[@electronicsrepairbasics_erb]

Hi, Do you check AMAZON Platform.

[@theebikeguy3852]

​@@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
