There is no body diode in Everycircuit
In real life mosfets have a body diode that conducts from source to drain, the gate has no control of this diode.
This example shows 100VDC applied from source to drain of a nmos fet (wired backwards). Current flow is negligible (1nA).
Two conclusions from mosfet testing, forward and backwards.
1. There is no body diode from source to drain.
2. There are two body diodes, one source to drain, the other anti parallel from drain to source.
The test results are indisputable. No body diode.
