High Efficiency Blue LED, Ø 3 mm Tinted Diffused Package
FEATURES
• GaN on SiC technology
• Standard Ø 3 mm (T-1) package
• Small mechanical tolerances
• Wide viewing angle
• Very high intensity
• Luminous intensity categorized
• ESD class 1
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC

DESCRIPTION
This device has been redesigned in 1998 replacing
SiC by GaN technology to meet the increasing
demand for high efficiency blue LEDs.
It is housed in a 3 mm tinted diffused plastic package.
All packing units are categorized in luminous intensity
groups. That allows users to assemble LEDs with
uniform appearance.
APPLICATIONS
• Status lights
• Off/on indicator
• Background illumination
• Readout lights
• Maintenance lights
• Legend light
PRODUCT GROUP AND PACKAGE DATA
• Product group: LED
• Package: 3 mm
• Product series: standard
• Angle of half intensity: ± 30°

Note:
Luminous intensity is tested at a current pulse duration of 25 ms and
an accuracy of ± 11 %.
The above type numbers represent the order groups which include
only a few brightness groups. Only one group will be shipped on
each bag (there will be no mixing of two groups on each bag).
In order to ensure availability, single brightness groups will not be
orderable.
In a similar manner for colors where wavelength groups are
measured and binned, single wavelength groups will be shipped on
any one bag.
In order to ensure availability, single wavelength groups will not be
orderable.
