Thermal Management

● The Absolute Maximum Junction 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

assembly. Ensure that when using the LEDs for the chosen application, heat is not concentrated in an area and properly managed

in the system/assembly.

● 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 junction temperature:

1) T J =T A +R θJA ?1?1W 2) T J =T S +R θJS ?1?1W

*T J =LED Junction Temperature: °C

T A =Ambient Temperature: °C

T S =Soldering Temperature (Die Heat Sink): °C

R θJA =Thermal Resistance from Junction to Ambient: °C/W

R θJS =Thermal Resistance from Junction to T S Measurement Point: °C/W
