Optocoupler, Phototransistor Output,
with Base Connection in SOIC-8 Package
IL205AT/206AT/207AT/208AT
Vishay Semiconductors
DESCRIPTION
The IL205AT/IL206AT/IL207AT/IL208AT are optically
coupled pairs with a gallium arsenide infrared LED and a
silicon NPN phototransistor. Signal information, including a
DC level, can be transmitted by the device while maintaining
a high degree of electrical isolation between input and
output. This family comes in a standard SOIC-8A small
outline package for surface mounting which makes them
ideally suited for high density application with limited space.
In addition to eliminating through-hole requirements, this
package conforms to standards for surface mounted
devices.
A specified minimum and maximum CTR allows a narrow
tolerance in the electrical design of the adjacent circuits. The
high BVCEO of 70 V gives a higher safety margin compared
to the industry standard 30 V.
FEATURES
• High BVCEO, 70 V
• Isolation test voltage, 4000 VRMS
• Industry standard SOIC-8A surface
mountable package
• Compatible with dual wave, vapor phase and
IR reflow soldering
• 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 Y
• CUL - file no. E52744, equivalent to CSA bulletin 5A
• 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.
