Very informative and knowledgeable vedeo. I always in waiting such type of informative tricks and Techniques. I like your all videos. Thank you so much.
Sir kindly asking asking why the capacity was added to the circuit if only a battery can manage to turn ON that MOSFET? Thank you for the video this method is the best, thank you sir
if mosfet have leakage in the channel, it will turn ON the LED as the the leaky channel have leakage above 10mA, to check P channel mosfet, we have to reverse Voltage polarity, LED and the capacitor connections
best regards yes optocoupler is working similar to a mechanical relay (one side LED simulates the relay coil. if a relay's coil is damaged the relay will not work & the output transistor behaves like the mechanical contacts of the relay, it will bad the next circuit will not respond ideally)
Sorry sir, the question is not about the uploaded video. I am troubleshooting a smps which pwm IC capacitor is 50v but it can only charge close to 1v. At the output am getting 1v as well.. I remember you did a video on how we can troubleshoot smps which pwm ic's capacitor have no charge. I replaced some diodes, capacitor, transistor, MOSFET which shorted. Can you refer me to videos that can help
welcome dear if the PWM ic's VCC capacitor is getting only 1 volt, that means there is some abnormality in circuit might be VCC capacitor is bad might be something wrong the output stage most common possibility is RCD snubber circuit (diode, resistor & capacitor connected between the mosfet drain and the main dc capacitor's +ve terminal. in parallel to the smps transformer's primary winding)
yes we can make arrangement, we can apply power. i attached this capacitor to just demonstrate the gate delayed discharging, otherwise we can connect just one resistor that will discharge the gate and mosfet will turn off
RESPECTED SIR , I want to know, how I can safely discharge HIGH VOLTAGE CAPACITORS ( MICROWAVE OVEN'S CAPACITOR) . I mean to ask about 2KV , 1 OR 2 microfarade CAPACITOR. . Please sir make one video abt HV CAPACITOR DISCHARGE TOOL.
use 220K 1/2 watt resistor and connect test probes. insulate this resistor in some small box connect test probes to the capacitor, it will discharge safely
Nice and direct application.....great reuse of RS-232 connector for mosfets. Thumbs up!!!
Thank you very much!
Zberdast sharing bai
thanks a lot dear sister
Thank you sir you sharing knowledge about testing of MOSFET AND GOOD INFORMATION
You are most welcome
Best explanation of circuit diagram and making projet. Thank you for teaching me. 👌
You are welcome
I love watching yout videos.I always learn from you!
Awesome! Thank you!

Very informative and knowledgeable vedeo. I always in waiting such type of informative tricks and Techniques. I like your all videos. Thank you so much.
Awesome deeply explained video. Did both N and P channels can be test on same circuit socket?. Thanks to upload video
Spectacular! Jazakallah bhai.
good evening brother
appreciable super work 👏
Amazing video dear friend, happy new week!!!
وعلیکم السلام بہت زیادہ اچھا ہے جی
nice video,thank you for continuous sharing,more power to your chanel
Thanks and welcome
Sir kindly asking asking why the capacity was added to the circuit if only a battery can manage to turn ON that MOSFET?
Thank you for the video this method is the best, thank you sir
Hi sir namaskaar 🙏
Very useful information and
simple circuit diagram
Thank you very much 🙏
What if the mosfet is leaky what could be the indication in the led, can we also use this on Pchannel Mosfet, and also in IGBT.... Thanks
if mosfet have leakage in the channel, it will turn ON the LED as the the leaky channel have leakage above 10mA,
to check P channel mosfet, we have to reverse Voltage polarity, LED and the capacitor connections
You are so incredibly in what u do thank you again. Continue wit your good work??? Can a optocoupler make a circuit dead.
best regards
yes optocoupler is working similar to a mechanical relay (one side LED simulates the relay coil. if a relay's coil is damaged the relay will not work
& the output transistor behaves like the mechanical contacts of the relay, it will bad the next circuit will not respond ideally)
Good job sir u made newb as professional..can u make variable power supply with short circuit protection pls..
hello it is a pleasure to view your very instructive vdo cheers
it is my pleasure
Thanks, very informative video!
My favorite channel
best regards and special thanks
Hi friend thanks for another informative video and thanks for the circuit as well
it is my pleasure
another good informative video
Sir pls make a video on adjustable dc60 volt and 10 ampere power supply circuit it would be very helpfull for us if you do it.thank you ❤️
Very nice keep it up bhai
Thank you so much 😀
sir, how about for p-channel mosfet, will this circuit work? .. or do we need to reverse the polarity of the dc power source? thank you
perfect. we will reverse the polarity, the LED & the capacitor
Salam M Haseeb, nice video. What is the purpose of the 10K resistor ? isn't the led enough to discharge the capacitor ? Thanks & Salam Aleikum
I think the 10k resister is discharging the gate rather than the LED…..I stand to be corrected however😅
Good luck 😃 useful video thanks 👍
Very nice video sir 👍 👏 💝
Thanks and welcome
Does this work also for voltage regulators and other Transistors?
Good Work Liked It # 33
Beautiful explain. Please sir make a video comparator ic inverting and noninverting function.
Thank you Sir but how do I test for a leaky mosfet?
a leakey mosfet will dtected on the LED, the LED will glow if the leakage is above 5 mAmp
Thank you Sir, much appreciated
good 👍👍👍
Excellent job
thanks a lot
Salam.
Nice video.
best regards 💗
علم دقيق ما شاء الله
الحمدلله
Very good video
thanks a lot
can use this circuit for test IGBT
Thank you very much sir 🙏🙏🙏
Most welcome
Thumbs up done nice video presentation sir can we used that in igbt transistor for testing sir
thanks a lot
yes it can be used for IGBT as well
hi! what happens if there is a shortcircuit Gate-Source? how we could turn the led on as in the case of Drain Source shortcircuit?
Sir watching for the second time can we used that for testing a p channel mosfet or p channel igbt sir tnx very very much
Good job 👍
Thanks for the visit
Very Nice.... Video Sirs
👍👍👍thanks this video
best regards
Nice work

welcome dear
if the PWM ic's VCC capacitor is getting only 1 volt, that means there is some abnormality in circuit
might be VCC capacitor is bad
might be something wrong the output stage
most common possibility is RCD snubber circuit (diode, resistor & capacitor connected between the mosfet drain and the main dc capacitor's +ve terminal. in parallel to the smps transformer's primary winding)
@@HaseebElectronics I will work on snubber circuit. Below is the image of the smps board.
Good job
best regards and special thanks
Good job sir 👍
thanks for this video
Most welcome
Nice
thanks a lot dear sister
Walikum Salaam Janab Bhai Saab
Good sir
Thanks and welcome
Can we put a small power supply at gate and avoid cap?
yes we can make arrangement, we can apply power. i attached this capacitor to just demonstrate the gate delayed discharging, otherwise we can connect just one resistor that will discharge the gate and mosfet will turn off
Mashallah 👌👍💖
love you sir ji
best regards
is that mosfet tester for N channel only?
yes it is for N-channel
@@HaseebElectronics how about P channel mosfet?
@@jetamorsolovideos i will demonstrate it soon
good thanks
it is my pleasure
please make video on "MOSFET Bootstrapping" and how it work?
Pls make video on how to test dual mosfets tks
👌👌👌👍
best regards and special thanks

Online ups invertor section schematic diagramme and practically video bana dijiye ....
sir can u make a IGBT tester?
To fake and original parts?
very nice , thx

@@HaseebElectronics ok . Thanks Sir . 🙏
You using communication cable as a breadboard, lol
Sir there is no power supply connection in your circuit diagram.
Allah bless you ?
👍👍🥀🥀
I love that !!
