The diagram below shows the recommended PCB solder pad layout for XLamp MK Family LeDs.
All measurements are ±.13 mm unless otherwise indicated.
CasE TEMpEraTurE (T

) MEasurEMEnT poInT
XLamp MT Family and MK Family LeD case temperature (T
s
) should be measured on the PCB surface, as close to the LeD’s thermal pad
as possible. This measurement point is shown in the pictures below.

It is not required to use a solder footprint for the thermal pad that is larger than the XLamp MT Family or MK Family LeD itself. In testing,
Cree has found such a solder pad to have insignificant impact on the resulting T
s
measurement.
