Please refer to the derating curves based on the terminal temperature. If any questions arise whether to use the Rated Ambient Temperature or the Rated Terminal Part Temperature, in your usage conditions, please give priority to the Rated Terminal Part Temperature. Prior to use and for more details refer to Introduction of the derating curves in the terminal part temperature in the beginning of the catalog. While using under high power, the temperature of the product may increase depending on the condition of heat dissipation from PCB. Be sure to check the terminal part temperature as well as precautions to use on delivery specification before use.
