1) Not subject to production test, specified by design.
2) Either one of the values has to be considered as worst case limitation.
3) This lifetime statement is an anticipation based on an extrapolation of Infineon's qualification test results. The actual lifetime
of a component depends on its form of application and type of use etc. and may deviate from such statement. The lifetime
statement shall in no event extend the agreed warranty period.
4) Triangular Pulse Shape (Inductance Discharge): I_D(t) = I_D(0)×(1 - t / t_pulse); 0 < t < t_pulse.
