I know this has been asked a few times already, but if we disregard the body diode, or say we tie the body to a low enough voltage that it wouldn't forward bias those diodes, then are modern FETs actually symmetric?
I ask this because the FETs I've used will often have, out of 6 pins, 4 will be dedicated to the drain, 1 to the source, and 1 to the gate. Even if we could control the body and bias it to a voltage of our own choosing, it seems like the FET has an asymmetry built in. I've primarily seen this on higher power FETs.
EDIT: My question is mainly about integrated output power FETs or discrete component FETs.
