DESCRIPTION
The single channel 5.0 Mb/s SFH6720T and
SFH6721T high speed optocoupler consists of a
GaAlAs infrared emitting diode, optically coupled with
an integrated photo detector. The detector
incorporates a Schmitt-Trigger stage for improved
noise immunity. A Faraday shield provides a common
mode transient immunity of 1000 V/µs at VCM = 50 V
for SFH6720T and 2500 V/µs at VCM = 400 V for
SFH6721T.
The SFH6720T and SFH6721T uses an industry
standard SOIC-8A package.
FEATURES
• Data Rate 5.0 Mb/s (2.5 Mb/s over Temperature)
• Buffer
• Isolation Test Voltage, 4000 VRMS
• TTL, LSTTL and CMOS Compatible
• Internal Shield for Very High Common
Mode

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.
