How to Test MOSFET transistor using Multimeter by some easy methods

[@swaminathan1959]

Brilliant simple to understand presentation. The presenter quickly comes to the point and walks you through the process without wasting any time. A very good gifted teacher indeed!! The minute I finished watching the video I quickly clicked on the "Like" and "Subscribe" button.

Bro, you did great!!! Straight to the point..and no grammers!!! The explanation on the design of the MOSFET is superb!!!

[@rainprie2799]

Thank you for your time making this informative video, I am repairing inverter now, this video help me understand the use and how this work.

[@realtoy1]

Thank you for the excellent explanation of how to quickly and easily understand how the MOSFET works and how to test it.

[@fardellp]

Very nice presntation - clearly explained and nicely demonstrated. Probably worth pointing out that the negative lead of some multimeters (particualrly the older analogue meters) have the black lead connected to the POSITIVE of the internal batttery. Also this will only work if the diode test position give a positive voltage of at least 5 V (normally - some may require a higher voltage)

Helped me to get my brain going again on fets. Im busy to do fault finding on small invertor so now i can make sure wheter my fets are ok or not. Thx for video

[@MrJamaltp]

Ur demonstration ever ever very usful, and practical &theoritical big thanks

[@TechStudyCell]

Thanks

[@sundars6549]

Well done ! Provided one is grounded properly, preferably with an anti ESD wrap. Some of these MOS devices get zapped pretty quickly otherwise !

[@TechStudyCell]

Thanks 😊

[@rsattahip]

You've never been to India, there's so much humidity there static electricity is not a problem.

[@leegenix]

@@rsattahip When I accidentally discharged the lead on my failed Motor scooter control unit, I got a large spark. Those Mosfets can store a charge for a long time and more than once. I would short them with a 1,000 Ohm resistor just in case from now on.

Thank you very much for this fine video. It helped me diagnose 2 out of 4 BS170 MOSFETs bad on my radio.

[@2pist]

Nicely done! I got more out of your 3 minute video than 1 hour of reading. I am going to use your test circuit to match mosfets. So simple! For a given input I can swap mosfets and compare their output. For P channel mosfets I can reverse the polarity. I want to balance them for audio output devices. Thank you!

In your test circuit,can't see how you get a negative reading on your DVM. +ve terminal of DVM is connected to G terminal of Fet (10kpot wiper).If pot set to bottom . Wouldn't it read 0 volts and then only go +ve as pot is increased?

5:32 The voltmeter is displaying -8.21 V. If the meter was connected between gate and source, it is impossible to show such value. The only possible way for the meter to display such value is when the meter is connected between gate and drain.

[@johndoggett808]

Yes. The V meter reading goes from -8.24V to +4.86V = 13.1V quite a trick with a 9V battery! The voltmeter is reading between whatever voltage the variable resistor is set to, and the voltage swing between the 100ohm resistor and the MOSFET.

[@Blue.star1]

Symmetrical supply, +9 0 -9 he didn't show us the picture , battery is hidden

[@johndoggett808]

@@Blue.star1 But there is only one 9v battery in the circuit diagram.

[@Blue.star1]

@@johndoggett808 watch carefully the wiring , may be no 2nd 9v batt. is there, how can we get - v unless he connects reverse measuring across somewhere else , he might have connected reverse as mosfet switches at -5 V

[@johndoggett808]

@@Blue.star1 I agree with Walkalone. When the MOSFET is off, the Meter’s + terminal is at about 0.8v (the Gate (0.8 = 9v - the 8.2v meter reading)). And the negative voltmeter Terminal is at +9V via the 100ohm resistor. When he turns the gate voltage up to 3.5v (9v-5.5v at 6:06) the MOSFET starts to turn no. After this the negative terminal of the volt meter is on the voltage divider between the 100 ohm resistor, and the partially turned on MOSFET. At 6:13 he turns the gate voltage to its highest value, and the MOSFET is pulling the negative voltmeter terminal down the 0v, and the positive voltmeter terminal is the gate voltage.

[@roimark358]

In testing/checking MOSFETs using Multi-meter, when the gate is charged, why some MOSFETs (N-channel & P-channel), the drain to source let us say 0.002 or less, others starts with more higher like 0.435 and running up as fast as a second or half a second until showing infinite? What does it mean? Does all MOSFETs behave like that?
