DESCRIPTION

The IL250/251/252/ILD250/251/252 are bidirectional input
optically coupled isolators consisting of two gallium arsenide
infrared LEDs coupled to a silicon NPN phototransistor per
channel.

The IL250/ILD250 has a minimum CTR of 50 %, the IL251/
ILD251 has a minimum CTR of 20 %, and the IL252/ILD252
has a minimum CTR of 100 %.

The IL250/IL251/IL252 are single channel optocouplers. The
ILD250/ILD251/ILD252 has two isolated channels in a single
DIP package.

FEATURES

• AC or polarity insensitive input

• Built-in reverse polarity input protection

• Improved CTR symmetry

• Industry standard DIP package

• Lead (Pb)-free component

• Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC

APPLICATIONS

• Ideal for AC signal detection and monitoring

AGENCY APPROVALS

• UL1577, file no. E52744 system code H or J, double
protection

• CSA 93751

• BSI IEC 60950; IEC 60065

• DIN EN 60747-5-5 available with option 1

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.
