Vishay Telefunken

Low Current 10 mm Seven Segment Display

Color Type Circuitry
High efficiency red TDSL3150 Common anode
High efficiency red TDSL3160 Common cathode

Description

The TDSL31.0 series are 10 mm character seven
segment low current LED displays in a very compact
package.
The displays are designed for a viewing distance up to
6 meters and available in high efficiency red. The grey
package surface and the evenly lighted untinted
segments provide an optimum on-off contrast.
All displays are categorized in luminous intensity
groups. That allows users to assemble displays with
uniform appearence.
Typical applications include instruments, panel
meters, point-of-sale terminals and household

equipment.

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. V arious 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-Telefunken products for any unintended or unauthorized application, the

buyer shall indemnify Vishay-Telefunken 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.
