Product Brief
Description
•
This White Colored surface-mount LED
comes in standard package dimension.
Package Size : 3.0x2.0x0.6mm
It has a substrate made up of a molded
plastic reflector sitting on top of a lead
frame.
The die is attached within the reflector
cavity and the cavity is encapsulated by
silicone.
The package design coupled with
careful selection of component materials
allow these products to perform with
high reliability.

Notes :
(1) Correlated Color Temperature is derived from the CIE 1931 Chromaticity diagram.
Color coordinate :
0.007
(2) Seoul Semiconductor maintains a tolerance of
7%
on Intensity and power measurements.
The luminous intensity IV was measured at the peak of the spatial pattern which may not be
aligned with the mechanical axis of the LED package.
(3) Calculated performance values are for reference only.

Notes :
(1) Tolerance is

(4) A zener diode is included to protect the product from ESD.
•
LED’s properties might be different from suggested values like above and below tables if
operation condition will be exceeded our parameter range. Care is to be taken that power
dissipation does not exceed the absolute maximum rating of the product.
All measurements were made under the standardized environment of Seoul Semiconductor.
