IPx6 Rated Surface Mount LED  
Application Note 5487  
1. Introduction  
2. Reference Documents  
The LED has been used in variable-message signs and full-  
IEC 60529: Degree of protection provided by enclosure  
color display applications for years. Its popularity in such (IP Code)  
applications stems from the vibrant and wide color gamut  
This standard provides a summarized definition of ingress  
that it produces, its long operating lifetime, and its ex-  
ceptional brightness which makes it suitable for outdoor  
viewing. The common LED package used in outdoor sign  
and display applications has typically been the through-  
hole package, due to its robust package design, high  
optical efficiency and shapeable radiation pattern.  
protection (IP) code designations and the test require-  
ments with which a package must comply to qualify for a  
specific IP coding.  
3. What is IP code?  
IP code is used to determine the degree of ingress pro-  
tection provided by an enclosure against solid foreign  
objects (first characteristic numeral), ingress of water  
(second characteristic numeral) and hazardous parts  
(additional letter). Since surface mount LED packages are a  
complete solid without air gap, the ingress of solid objects  
(such as dust or dirt) is of less concern. As such, this appli-  
cation note focuses mainly on the ingress of water within  
the surface mount package.  
Thanks to the advancement of surface mount LED  
package design and materials in recent years, coupled  
with the progress in LED die efficiency, surface mount  
LED packaging can now deliver the required brightness  
for outdoor sign and display applications. In order to fully  
enable their potential for use in harsh outdoor environ-  
ments, Avago has developed a series of surface mount  
tricolor packages with high reliability and durability  
that fully satisfy the requirements for outdoor applica-  
tions. With our patented package design and proprietary  
material, these packages comply with IPX6 coding per IEC  
60529 standard for protection against water.  
The objective of this Application Note is to provide users a  
general understanding of the IPX6 coding, its advantages  
as well as precautions needed when using these LEDs.
