2SJ109

Hi,

There is a series of old 3-pin N-cannel low noise & switching J-FET's called J108, J109 & J110. I think Siliconix began with them in the end of the 70's.
These types were later made by almost all manufacturers and are in large stocks. Just make a search on "siliconix j109" to see.

These are most confusing as the japanese don't print 2S before J109 on the actual 2SJ109 device.

So the 3-leg J109 is now misstaken for 2SJ109, even by many honest suppliers (if there are any).

So just ask if there is 3 or 7 legs on them.

JohanB :)

Hi there
It does appears that they are confusing them with J109 please see entry by JohanB

I will try to find out more.

If by chance I have stumbled on a source that had a large stock stashed away I will post again, but at this point I am 90% biased toward mistaken numbers.
 
Hi members,

I've thrown out a couple of hooks myself, for the 2SJ109-GR, as I've many 100's genuine Toshiba original 2SK389-GR's myself, but no 2SJ109-GR.

I submit an answer here that can be real or fakes. Even if I order samples that works, I don't know if the delivery later on will be real or fakes.

I give away this contact information to dyiAudio members, if anybody wants to investigate this company and offer. I cannot myself take the economical risk and go further with this quotation.

As they are situated in Schenzen in China, it would be difficult to prosecuting or demanding refound, if they are selling fakes.

Or they may be have been cheated themselfes, and don't know if they are fakes. Quite tricky for a non-technical trading company to judge....

If there is some members here in the Schenzen region or anywhere, that can investigate these claimed-to-be-real 2SJ109-GR, and supply the information here in the forum??????

Here is the return-mail I got and a picture of 2 devices, that is attached down here (with the same resolution i had from them).

Only to compare outlines and printing, I have also attached a second picture of my own 2SK389-GR (guaranteed NOS Toshibas).

Are these "Shenzen 109's" looking a little strange on the printing surface? Are they grinded on that surface and reprinted? :rolleyes:
