Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to GND lead. Stresses beyond those listed under "
Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only; and
functional operation of the device at these or any other condition beyond those indicated in the “Recommended
Operating Conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may
affect device reliability. The thermal resistance and power dissipation ratings are measured under board mounted
and still air conditions. Ambient temperature (TA) is 25°C, unless otherwise specified.

Parameter Trends vs. Temperature
www.DataSheet4U.com
Figures illustrated in this chapter provide information on the experimental performance of the AUIRS4426S HVIC.
The line plotted in each figure is generated from actual lab data. A large number of individual samples were tested at
three temperatures (-40 ºC, 25 ºC, and 125 ºC) with supply voltage of 15V in order to generate the experimental
curve. The line consists of three data points (one data point at each of the tested temperatures) that have been
connected together to illustrate the understood trend. The individual data points on the Typ. curve were determined
by calculating the averaged experimental value of the parameter (for a given temperature).
