Vishay Semiconductors
DESCRIPTION
The SFH615A (DIP) and SFH6156 (SMD) feature a variety
of transfer ratios, low coupling capacitance and high isolation
voltage. These couplers have a GaAs infrared diode emitter,
which is optically coupled to a silicon planar phototransistor
detector, and is incorporated in a plastic DIP-4 or SMD
package.
The coupling devices are designed for signal transmission
between two electrically separated circuits.
The couplers are end-stackable with 2.54 mm lead spacing.
Creepage and clearance distances of > 8.0 mm are achieved
with option 6. This version complies with IEC 60950
(DIN VDE 0805) for reinforced insulation up to an operation
voltage of 400 VRMS or DC. Specifications subject to change.
FEATURES
• Excellent CTR linearity depending on forward
current
• Isolation test voltage, 5300 VRMS
• Fast switching times
• Low CTR degradation
• Low coupling capacitance
• Lead (Pb)-free component
• Component in accordance to RoHS 2002/95/EC and
WEEE 2002/96/EC
APPLICATIONS
• Switchmode power supply
• Telecom
• Battery powered equipment
AGENCY APPROVALS
• UL1577, file no. E52744 system code H or J, double
protection
• DIN EN 60747-5-5 (VDE 0884) available with option 1
Note
For additional information on the available options refer to option information. See tape and reel section for 4 pin optocouplers T0 with 90°
rotation.

Notes
(1) Tamb = 25 °C, unless otherwise specified.
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute maximum
ratings for extended periods of the time can adversely affect reliability.
(2) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).

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.
