2SK79 pinout?

[mbrennwa]

I can't find the pinout of the 2SK79 VFETs, and my DCA75 tester can't tell the difference between gate and source. Help!

Try this: http://www.amplimos.it/images/2SK79_data.pdf

That is the bottom view shown.

One problem though, this data sheet shows it as a normal transistor!

That's just a standard drawing, so use C -> D, E -> S, and B -> G.

I also saw that datasheet from the Amplimos website with the BTJ pin labels. I hoped that the BJT labels would correlate to the JFET pin as suggested by rayma, but they don't. Sorry, I should have mentioned that in my first post.

In the meantime, I was able to figure out the pinout by looking at some PCB photos and schematics I found on the web. I attached a drawing of the pinout. When I connected my 2SK79 following this pinout, I got the curves in the attachment with no smoke or other permanent injuries, so I guess my drawing is correct.

I posted complete datasheets for K79 a while ago here ==> V-FET / SIT data sheets...

Cheers!
