Has anyone used this instead of a 2N7000 or BS170? Is it higher gain? 8)
Hi, isn't 2N7002 surface mount? Jered
So far I've used 2N7000 with good results
I think the two you refferred to are listed as subs on some schematics?
I always bias those mosfets anyway.
Hi WG,
Looking at the datasheet here: http://www.fairchildsemi.com/pf/2N/2N7002.html
It appears the 2N7002 is the surface mount equiv. of 2N7000.

I thouhgt I had seen some 2N7002's in the 92 format and was looking at a spec sheet that indicated different values for the 2N7000 and 2N7002. I don't know enough about it to determine which characteristics relate to more or less gain. Don't remember if it was Phillips or Fairchild. Hmmm
I was thinking a higher gain 2N7000 might come in handy for the Blue Magic/Peppermill circuits. 8)
WG-
the 2N7002 is a surface mount 27000.
Try a BS170, it should have a good bit more gain. You are looking for transconductance, signified as gfs on datasheets. The BS170 is 320mS and the 2N7000 is 100mS. On average that is, device variation exists.
How about the 7008? Anyone have any experience with these? A sub for the 7000 perhaps? I've got 7000's also, but lucked out with 5 free 7008's and need something to do with them.
I tried 2n7008's in the multiface from ROG, and they sounded very similar to the 7000's.
Didn't fiddle too much with them either, i was just curious to see id they would work (which they did).

See for yourself:

OK. The Vishay's seem to have the same minimum value for forward transconductance for the 2N7000's and the BS170. Thanks for the info. 8)
