oC means that the behaviour of the device will not be affected for junction temperature lower then 150 oC . For higher
temperature, the thermal protection circuit will begin its action reducing the Icl limit according with the power dissipation. Chip temperature is
a function of the Rth of the whole system in which the device with be operating.
