Note 1: All data listed in the above graphs, except for derating data, has been developed from actual products tested at 25°C. This data is considered typical data for the ISR.
Note 2: Thermal derating graphs are developed in different air flow rates as indicated on each graph, with or without the heat tab, soldered in a printed circuit board. (See Thermal Application Notes.)
