Heat Dissipation from NC4U13xx depending on Tj Application Note

PublishTime：2021-12-15

The light output of LEDs is reduced under the influence of heat generation. When LEDs are operated over the absolute maximum junction temperature (T-jmax), the performance is severely degraded. It is critical to design the heat dissipation not to exceed the T-jmax for NC4U13xx to achieve a high reliability and a high performance. This document provides the Tj evaluation results under three conditions by using different heat sinks. Please use the data as reference for NC4U13xx's thermal design at your site.
