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 reel (there will be no mixing of two groups on each reel).

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 reel.

In order to ensure availability, single wavelength groups will not be
orderable.

DRY PACKING

The reel is packed in an anti-humidity bag to protect
the devices from absorbing moisture during transpor­tation and storage.

Aluminium bag

RECOMMENDED METHOD OF STORAGE

Dry box storage is recommended as soon as the alu­minium bag has been opened to prevent moisture
absorption. The following conditions should be
observed, if dry boxes are not available:

• Storage temperature 10 °C to 30 °C

• Storage humidity ≤ 60 % RH max.
After more than 672 hours under these conditions

moisture content will be too high for reflow soldering.
In case of moisture absorption, the devices will recover

to the former condition by drying under the following
condition:

192 hours at 40 °C + 5 °C/ - 0 °C and < 5 % RH
(dry air/nitrogen) or

96 hours at 60 °C + 5 °C and < 5 % RH for all device
containers or

24 hours at 100 °C + 5 °C not suitable for reel or tubes.
An EIA JEDEC Standard JESD22-A112 Level 2a label

is included on all dry bags.

CAUTION

1. Shelf life in sealed bag 12 months at <40°C and < 90% relative humidity (RH)

2. After this bag is opened devices that will be subjected to infrared reflow,
vapor-phase reflow, or equivalent processing (peak package body temp.

260°C) must be:

a) Mounted within
b) Stored at <1

3. Devices require baking before mounting if:
a) Humidity Indicator Card is >10% when read at 23°C +
b) 2a or 2b is not met.

4. If baking is required, devices may be baked for:

192 hours
96 hours

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.
