Fake BU2508DF Horizontal Output Transistor
Some years back i had an experienced about purchasing a fake horizontal output transistor (HOT). The HOT number was Bu2508df and the price was below the market price. I do not know that it was a fake HOT until i tested the HOT on monitors. Some monitors worked perfectly fine but others causes power blink. When i replaced with another HOT (original) the monitor worked ok! I then compared the original and the fake HOT and found that the original one the surface are more shining, heavier and have a short horizontal line across the top center part of the HOT. While the fake HOT have a dim marking and without the horizontal line. Both have the word Philippines endorsed on the HOT. The moral of the story here is that if you found some component's price are far below the market price then you have to be careful of buying a fake components.

these arent fake transistors but are sub-standard components. the factories that are producing these products are not following the supposed quality control procedures.
it is very difficult for a chip maker to produce a "fake" transistor since it will cost them the same amount in processing their chips compared to that of the original. so what they do is bypass the quality control procedures.
