t0: Turn on into a short circuit
tm : Measurementpoint for ID(lim)
t1: Activation of the fast temperature sensor and
regulation of the drain current to a level wher
the junction temperature remains constant.
t2: Thermal shutdown caused by the second
temperature sensor, achieved by an
integrating measurement.
