Description
The SFH6943 is a four channel mini-optocoupler suit-
able for high density packaged PCB application. It
has a minimum of 1768 VRMS isolation from input to

output. The device consists of four phototransistors
as detectors. Each channel is individually controlled.
The optocoupler is housed in a SOT223/10 package.
All the cathodes of the input LEDs and all the collec-
tors of the output transistors are common enabling a
pin count reduction from 16 pins to 10 pins-a signifi-
cant space savings as compared to four channels that
are electrically isolated individually.

Absolute Maximum Ratings
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 Rating for extended periods of the time can adversely affect reliability.

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
operatingsystems 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.
