3. Not subjected to production testing

4. To ensure long term reliability under heavy overload or short circuit conditions, protection and related diagnostic signals must be used

together with a proper hardware/software strategy. If the devices operates under abnormal conditions this hardware/software solutions

must limit the duration and number of activation cycles.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.
