4.7 Thermal Information

Thermal information is standard in the majority of TI device data sheets. An example of a table that is found in most ESD protection device data sheets is shown in Table 4-8. The most commonly reported metric is the junction to ambient thermal resistance, RθJA. This metric measures the thermal performance of an IC package mounted on a specific test coupon and is intended to be used to compare the thermal performance of a package for a TI part to other companies. For more detail into the specifics of each thermal metric, refer to the application note Semiconductor and IC Package Thermal Metrics.
