There's no test that will tell if a part is fake or not. A fake part could very well measure the same as an authentic one.Thanks for reply
How you think of this method of testing?, I think it can be good way for test and be sure of the component used, if fake or original it’s for mosfets
I think for transistor and IGBT can be somehow like this comparing test with data sheet readings and applying load on the part
Please look and let me know how you think
Maybe, have you watched the video?There's no test that will tell if a part is fake or not. A fake part could very well measure the same as an authentic one.
One way is to use a ready-made component tester. Another way can be looking at a particular component's datasheet and trying an application circuit mentioned there.Hello everyone
I’m working daily on repair electronic boards, mainly UPS machines within different capacities
Most of the problems I see , is blown mosfet, Or IGBT or high voltage doide
When I purchase from local market, the complements for replace, sometimes they are fake, like few weeks ago, I’ve checked mosfet jcs3205 and when I test before install, it gives strange readings, although it’s new and never soldered before
One time before also, over install mosfets and the machine worked fine and everything ok, but when there a load these replaced components damage again, and only solved this by replacing different components from similar board, “ not from supplier but from trusted stock “
Is there any way to check if the components fake or real?, have you met anything like this while you’re repairing electronics?
Please lemme know
Again: Just because the measured parameters meet the data sheet values, it doesn't mean the component is authentic. All you've proved is that the part meets the specifications, nothing more can be inferred.Maybe, have you watched the video?
Okay, thanksAgain: Just because the measured parameters meet the data sheet values, it doesn't mean the component is authentic. All you've proved is that the part meets the specifications, nothing more can be inferred.
Just because my photograph of the Mona Lisa is very high resolution doesn't mean it IS the Mona Lisa.

How can I know that?are your parts the current production version or something they walked away from years back? L
