All Transistors Faked on AliExpress?

Rumors say that a lot or even most of the active parts like transistors on AliExpress are fake. This would have severe consequences for our purchasing. So, let’s check my randomly purchased transistors to see if this is true and also establish a simple procedure to prevent obvious fakes in the future. In my last video, we discussed transistors, and I mentioned that parts on AliExpress might be faked. This sparked quite some comments, sometimes quite harsh. Today I will show you how you can test your transistors to make sure they fulfill the most important claims of the datasheets. This video is intended for Makers, not for manufacturers of products. To save us money and hassle, we will: – Understand how we can test MOSFETS. They are the cornerstone of our “survival kit.” – Build a simple setup to do the tests – Test my transistors purchased on AliExpress to see how many are faked products – I will propose a simple and fast “incoming inspection” for your AliExpress purchases to avoid you are cheated I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.
