Hi,
I have some transistors (i think) that I cannot identify.

They are labelled FFT0601 in a TO-72 metal can, 4 lead

The 1st F is bold and larger than the rest of the part number and I thought
that would indicate Fairchild.
I think it's a fet or dual gate fet or jfet

Cannot find it in any of the usual checks

Can anyone shed some light and provide a datasheet?

Thanks
Greg

Could be Ferranti, although last time I saw their logo I remeber it to be
based around a diode, but google gets me a bold F.

your multimeter can answer that one.

sounds like ferranti :)

HTH.

If it is upright, with serifs, then it is probably Fujitsu.

It's an FT0601 Dual Gate N-Channel MOSFET.

This is an equivalent:

FWIW, FT0607 and FT0608 are triacs made by Fagor.

Hi all,
thanks for the info.

I eventually went back to freetradezone (now partminer). I could find it in
the inventory search as a fairchild part, but in the data search it came up
as not found, which I consider strange.

Thanks for the nte info. I'll add them to my usual checks from now on.

Cheers
Greg
