Anyone have any dealings with this China semi-conducter manufacturer? They have MRF477 listed for like $6.98 and make some other obsolete transistors. Might be worth a shot to get one and try it out. There web site says they are ISO certified for what that is worth. The data sheet mirrors the Motorola specs.

Be advised; there are a lot of FAKE transistors out there.
Been suckered myself - just once.
Happened on eBay . . .

What was the issue with the one you bought? Making that type transistor is not rocket science, much easier than making a CPU or IC chip. Power transistors should be an easy make. They are not Motorola and don't claim to be but with the price of a Motorola if you can find one for 50 bucks or more 6.98 could be worth it.

Final & driver transistors. Some voltage regulators. Stuff like that.

I emailed them about minimum orders and you must buy 10 so that shoots that idea out. Free shipping they said but that is 70 bucks worth. I don't want a lifetime supply.

I ordered some 2078's from a "chinese" dealer and guess what? no output.
