C case temperature, refer to Figures 1 and 2. To avoid exceeding the design maximum virtual
junction temperature, these ratings should not be exceeded. Due to variations in individual device electrical characteristics and thermal
resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation.
