yep, the model lettering is clearly quite different on the fakes

I wouldnt trust anything ordered at alibaba for high end electronics, not a chance

Didnt take long, did it.

dont go by just the lettering differences. The original R100's and some R100As used the more 'white' letter printing. They also used a more 'shiny' legs and drain substrate backing.

That being said, I've had a couple of parts searchers seek these out lately. They are saying any offer right now are from seedy sources and likely fake. So really buyer beware.
The IC district of China can unfortuntely produce whatever you want for a part in printing in a couple of days notice.

R100's of any sort will have a much lower VgS test then any IRF240.

Does UJT mean Uni Junction Transistor?
