[sdiy] BS170, low leakage

[Czech Martin]

I included them into my list of possibly usefull devices.
Possible advantage: thick gate oxide allows for NO ESD
protection, thus very low gate-source leakage.
This could be different in an IC solution.
Second advantage: you have all three terminals s g d (bulk
however tied to s, which is sometimes not so good)
and you don't have to worry about chip substrate leakage/latch up
etc. Just an almost ideal DMOST, all terminals floating.


m.c.

I just checked my stash and found that I had bought some of these a few 
years ago. Was someone else also recommending them?  What would their 
advantage be over the better IC switches?
