Is there a four pin MOSFET where the substrate can be left disconnected from the source, and thus eliminating the body diode effect, but that can still be driven as a normal MOSFET ?
Both drain and source have parasitic diodes:I think that by the very nature of their design, MOSFETs have a body diode ie the positively doped source and drain and the negatively doped channel in an enhancement mode MOSFET.
Most likely. The diodes are always going to be there. You'll get better answers if you post a schematic.Would I be correct to say that, even if I could leave the fourth body terminal of a MOSFET tied to ground or disconnected, it probably would not solve the problem of the parasitic diodes, and that regardless of which type I use, they would be unsuitable for the cct I have proposed ?
Your story doesn't pass the sniff test half way around the world in Ohio.And ?
