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 where

the junction temperature remains constant.

t2: Thermal shutdown caused by the second

temperature sensor, achieved by an

integrating measurement.
