anything good in fake 2sa1943 and 2sa5200?

[xeclipse]

Hi guys,
talk of a beginner in solid state,and one is here asking some questions.
I just purchased some 'toshiba' 2sa1943 and 2sc5200,the ones with a glossy rectangles with clear writings on them.I am convinced they are fake.Is there anything good from these counterfeits apart from seeing how fast they produce smoke?

Anything counterfeit is useless as you can never rely on it, the characteristics will almost certainly be nothing like the originals too.

Learn from it, play around with them, but never use them for any serious work.

Edit... if your quick like this the edit's don't show 😉

Edit... again

Regard them as 2955/3055's since as that's probably what the dies are.
