They show and then discuss at length a very marked assymmetry between forward and reverse Vgs / Ids or Vds characteristics. The reverse characteristics are generally significantly superior (in terms of ability to enhance the device to those in the forward direction. | |

| Aug 26, 2019 at 14:30 | comment | added | Elliot Alderson | I am controlling \$V_{DS}\$. As long as \$V_{DS}\$ is below about 0.6V then the body diode will remain reverse-biased and will not contribute to \$I_{DS}\$. I don't know what you mean by "observed in one axis". | |
| Aug 26, 2019 at 0:59 | comment | added | ssa2 | In last section, why Vth and Vf is observed in one axis? Vth is value about Vgs, and Vf is value about Vds. I can't understand the sentence "before the body diode started conducting". Which voltage are you controlling in this context? | |
