DESCRIPTION

The VLMW621. is one of the most robust and light
efficient LEDs in the market. The small size and wide
viewing angle make these LEDs a prime choice for
backlighting applications and front panel indicators,
especially where space is at a premium. Its ceramic
package makes it the ideal light source in applications
of high thermal considerations allowing the additional
current drive for a maximum light output while
maintaining a high service life of up to 50K h. The
reflector inside this package is filled with a mixture of
silicone and TAG phosphor. The TAG phosphor
converts the blue emission partially to yellow, which
mixes with the remaining blue to white.

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, each single wavelength group is packed in a single reel.
In order to ensure availability, single wavelength groups can not be ordered.

DRY PACKING

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

Aluminum bag

Label

Reel

15973

RECOMMENDED METHOD OF STORAGE

Dry box storage is recommended as soon as the
aluminum 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 72 h 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 h at 40 °C + 5 °C/- 0 °C and < 5 % RH
(dry air/nitrogen) or

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

24 h at 100 °C + 5 °C not suitable for reel or tubes.
An EIA JEDEC standard JESD22-A112 level 4 label is

included on all aluminum dry bags.

CAUTION

This bag contains

MOISTURE-SENSITIVE DEVICES

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 soldering
reflow or equivalent processing (peak package body temp. 260 °C)
must be
2a. Mounted within 72 hours at factory condition of < 30 °C/60 % RH or
2b. Stored at < 5 % RH

3. Devices require baking befor mounting if:
Humidity Indicator Card is > 10 % when read at 23 °C ± 5 °C or
2a. or 2b. are not met.

4. If baking is required, devices may be baked for:
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 125 °C ± 5 °C not suitable for reels or tubes

ESD PRECAUTION

Proper storage and handling procedures should be
followed to prevent ESD damage to the devices
especially when they are removed from the antistatic
shielding bag. Electro-static sensitive devices warning
labels are on the packaging.

FINAL PACKING

The sealed reel is packed into a cardboard box. A
secondary cardboard box is used for shipping
purposes.

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.

The IEC/EN standards require that the desired classification Accessible Emission Limit shall not be exceeded
in “Normal” and “Single Fault Conditions”. This product is in Compliance with the requirement in
CEN/IEC/EN60825-1 to ensure that required classifications are not exceeded in single fault conditions.

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.
