/diy/ - Do It Yourself

ive spent half an hour reading about mosfets and i think i get it now
from what i understand source and drain get shorted when theres a voltage between gate and body
why is body connected to source?
is there any real benefit to doing that because its much harder to understand
it also prevents a single mosfet from swithing ac loads because it forms a diode betweem source and drain
also why is it done with a p+ area?

get the fuck out of here with that

Not him but that's a nice way to look at it. I've been looking at the semiconductor geometry of JFETs and MOSFETs a bit lately and I see diagrams of MOSFETs with no particular difference between the D and S. Actually searching for images with the substrate connection give me ones that do show such a bias, which solves a little mystery in my mind, and clarifies the nature of the MOSFET in general.
