DESCRIPTION
High Intensity LED with typical color coordinates
x = 0.33, y = 0.33 (typical color temperature 5500 k).
This LED emits white light with a high color rendering
index.
The emission spectrum is tuned for ideal white, without
APPLICATIONS
• Indicator and backlighting
• Indoor and outdoor message panels
• Alternative to incandescent lamps
• Marker lights
the impression of being blue shaded or "cold". The
package is a standard 3 mm.
The internal reflector is filled with a compound of TAG
phosphor and an elastic resin.
Therefore the chip is better protected against temperature cycle stress.
The phosphor converts the blue emission of the InGaN
chip partially to amber, which mixes with the remaining
blue to produce white.

Ozone Depleting Substances Policy Statement
It is the policy of Vishay Semiconductor GmbH to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating
systems with respect to their impact on the health and safety of our employees and the public, as well as their
impact on the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as
ozone depleting substances (ODSs).
The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and
forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban
on these substances.
Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of
ODSs listed in the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively
2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency (EPA) in the USA
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively.
Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting
substances and do not contain such substances.
We reserve the right to make changes to improve technical design
and may do so without further notice.
Parameters can vary in different applications. All operating parameters must be validated for each customer
application by the customer. Should the buyer use Vishay Semiconductors products for any unintended or
unauthorized application, the buyer shall indemnify Vishay Semiconductors against all claims, costs,
damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death
associated with such unintended or unauthorized use.
