Hi!
How about these new (2003 and until now) transistors used in a DIY
brushless motor controller og just ESC:
*Vertical Power JFET*
"On" @ +0,7V Rds(on) fx< 4,5 mOhm:
http://www.lovoltech.com/App_Notes/Application_Notes.htm
Fx Vgs(th)=-0,25V (depletion) or +0,38V (enhancement), max. 5-50A,
Vds(max): 20-25V, Vgs(max): -10V.
Are availably as enhancement (off@0Vgs) and depletion (on@0Vgs).
http://www.lovoltech.com/Products/Products.htm
They are ideal for DC-DC converters; used with batteries, accumulators
og solar cells/photovoltaics.

The depletion Power JFET could be used as efficient diodes (max. -10V
non-conducting and 0V conducting) by connecting the gate with drain as
one terminal and source as the other terminal?
Can they be bought in Europe?

Goedendag Glenn,
Ask around in this excellent diy brushless controller thread or the diy
electronics subforum that contains the thread:

adult group (???) no worries, it's safe to go there)

Glenn,
You could try http://www.nessel-elektronik.de/ (put your sunglasses on, it
used to be even worse).
Or contact people in the forum at www.rc-unionen.dk , in the 'elektronik' or
the 'El-Hjørnet' subforum. Or this German e-motors and controllers subforum:
