Output i-v characteristics of power MOSFET:

Transconductance is the change in the drain current divided by the small change in the gate/source voltage with a constant drain/source voltage.

\({g_m} = \frac{{{\rm{\Delta }}{I_D}}}{{{\rm{\Delta }}{V_{GS}}}}\)

It is an important factor in the steady-state characteristics.
