Introduction
datasheet. The addendum provides thermal performance information that may be
critical in the design and development of system applications. All electrical,
application, and packaging information is provided in the datasheet.
Packaging and Thermal Considerations
There is a single heat source (P), a single junction temperature (T

package to another in a standardized environment. This methodology is not meant
to and will not predict the performance of a package in an application-specific
environment. Stated values were obtained by measurement and simulation
according to the standards listed below.
