Optocoupler, Photodarlington Output,
High Gain (Dual, Quad Channel)
ILD32, ILQ32
Vishay Semiconductors
DESCRIPTION
The ILD32, ILQ32 are optically coupled isolators with a
gallium arsenide infrared LED and a silicon photodarlington
sensor. Switching can be achieved while maintaining a high
degree of isolation between driving and load circuits.
These optocouplers can be used to replace reed and
mercury relays with advantages of long life, high speed
switching and elimination of magnetic fields.
FEATURES
Isolation test voltage, 5300 VRMS
High isolation resistance, 1011Ω typical
Low coupling capacitance
Standard plastic DIP package
Lead (Pb)-free component
Component in accordance to RoHS
2002/95/EC and WEEE 2002/96/EC
AGENCY APPROVALS
UL1577, file no. E52744 system code H or J, double
protection
DIN EN 60747-5-5 (VDE 0884) available with option 1
BSI IEC 60950; IEC 60065

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.
