What is power dissipation index?

The Power Dissipation Index (PDI) is a measure used to evaluate the thermal performance of electronic devices, particularly in terms of how effectively they can dissipate heat generated during operation. It takes into account factors such as the power consumed by the device and its ability to manage heat through design and materials. A higher PDI indicates better thermal management, which is crucial for ensuring reliability and longevity in electronic systems. It is particularly significant in applications where overheating can lead to failure or reduced efficiency.
