Description
The TSOP18..SB3V – series are miniaturized receiv-
ers for infrared remote control systems. PIN diode and
preamplifier are assembled on lead frame, the epoxy
package is designed as IR filter.
The demodulated output signal can directly be de-
coded by a microprocessor. The main benefit is the
reliable function even in disturbed ambient and the
protection against uncontrolled output pulses.

Suitable Data Format
The circuit of the TSOP18..SB3V is designed in that Some examples for suitable data format are:
way that unexpected output pulses due to noise or NEC Code (repetitive pulse), NEC Code (repetitive
disturbance signals are avoided. A bandpassfilter, an data), Toshiba Micom Format, Sharp Code, RC5
integrator stage and an automatic gain control are Code, RECS–80 Code, R–2000 Code.
used to suppress such disturbances.
When a disturbance signal is applied to the
TSOP18..SB3V it can still receive the data signal.
However the sensitivity is reduced to that level that no
unexpected pulses will occure.
The distinguishing mark between data signal ( not
suppressed) and disturbance signal (supressed) are
carrier frequency, burst length and Signal Gap Time
(see diagram below).
The data signal should fullfill the following condition:
Some examples for such disturbance signals which
are suppressed by the TSOP18..SB3V are:
•
Carrier frequency should be close to center fre-
quency of the bandpass (e.g. 38kHz).
•
DC light (e.g. from tungsten bulb or sunlight),
•
•
Burst length should be 6 cycles/burst or longer.
After each burst a gap time of at least 9 cycles is

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-Telefunken products for any unintended or unauthorized application, the
buyer shall indemnify Vishay-Telefunken 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.
