Thermal Management
● The Absolute Maximum Junion Temperature (T J ) must not be exceeded under any circumstances. The increase in the
temperature of an LED while in operation may vary depending on the PCB thermal resistance and the density of LEDs on the PCB
embly. Ensure that when using the LEDs for the chosen application, heat is not concentrated in an area and properly managed
in the system/embly.
● The operating current should be determined by considering the temperature conditions surrounding the LED (i.e. T A ). Ensure that
when operating the LED, proper measures are taken to dissipate the heat.
● The following two equations can be used to calculate the LED junion temperature:
1) T J =T A +R θJA ?1?1W 2) T J =T S +R θJS ?1?1W
*T J =LED Junion Temperature: °C
T A =Ambient Temperature: °C
T S =Soldering Temperature (Die Heat Sink): °C
R θJA =Thermal Resistance from Junion to Ambient: °C/W
R θJS =Thermal Resistance from Junion to T S Measurement Point: °C/W
