PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses. 96 12582 Features D D D D D Special Features Photo detector and preamplifier in one package Internal filter for PCM frequency TTL and CMOS compatibility Output active low D Small size package D Supply voltage 3–6 Volt D Enhanced immunity against all kinds of disturbance light D No occurrence of disturbance pulses at Improved shielding against electrical field disturbance the output D Short settling time after power on (<200ms) D Suitable burst length ≥6 cycles/burst Block Diagram 3 Control Circuit Input 80 kW 1 PIN AGC Band Pass VS OUT Demodulator 2 GND 16249 Document Number 82133 Rev. 2, 13-Jun-00 www.vishay.de • FaxBack +1-408-970-5600 1 (7) TSOP18..SS3VA Vishay Telefunken Absolute Maximum Ratings Tamb = 25_C Parameter Supply Voltage Supply Current Output Voltage Output Current Junction Temperature Storage Temperature Range Operating Temperature Range Power Consumption Soldering Temperature Test Conditions (Pin 3) (Pin 3) (Pin 1) (Pin 1) x (Tamb 85 °C) t 10 s, 1 mm from case x Symbol VS IS VO IO Tj Tstg Tamb Ptot Tsd Value –0.3...6.0 5 –0.3...6.0 5 100 –25...+85 –25...+85 50 260 Unit V mA V mA °C °C °C mW °C Typ 0.8 1.0 Unit mA mA V m Basic Characteristics Tamb = 25_C Parameter Supply y Current ((Pin 3)) Test Conditions VS = 3 V, Ev = 0 VS = 3 V, Ev = 40 klx, sunlight Supply Voltage (Pin 3) Transmission Distance Ev = 0, test signal see fig.6, IR diode TSAL6200, IF = 300 mA Output Voltage Low (Pin 1) IOSL = 0.5 mA,Ee = 0.7 mW/m2, f = fo Irradiance (30 – 40 kHz) Pulse width tolerance: tpi – 4/fo < tpo < tpi + 5/fo, test signal see fig.6 Irradiance (56 kHz) Pulse width tolerance: tpi – 4/fo < tpo < tpi + 5/fo, test signal see fig.6 Irradiance Directivity Angle of half transmission distance Symbol ISD ISH VS d Min 0.5 3.0 Max 1.1 6.0 35 VOSL Ee min 0.3 250 0.5 mV mW/m2 Ee min 0.4 0.7 mW/m2 Ee max ϕ1/2 W/m2 deg 30 ±45 Application Circuit 330 3 TSOP18..SS3VA TSAL62.. 1 m 4.7 F *) W *) +VS W >10 k recomm. mC 2 GND 15803 www.vishay.de • FaxBack +1-408-970-5600 2 (7) *) recommended to suppress power supply disturbance Document Number 82133 Rev. 2, 13-Jun-00 TSOP18..SS3VA Vishay Telefunken Suitable Data Format The circuit of the TSOP18..SS3VA is designed in that way that unexpected output pulses due to noise or disturbance signals are avoided. A bandpassfilter, an integrator stage and an automatic gain control are used to suppress such disturbances. The distinguishing mark between data signal ( not suppressed) and disturbance signal (supressed) are carrier frequency, burst length and Signal Gap Time (see diagram below). Some examples for suitable data format are: NEC Code (repetitive pulse), NEC Code (repetitive data), Toshiba Micom Format, Sharp Code, RC5 Code, RECS–80 Code, R–2000 Code. The data signal should fullfill the following condition: Some examples for such disturbance signals which are suppressed by the TSOP18..SS3VA are: • Carrier frequency should be close to center frequency of the bandpass (e.g. 38kHz). • Burst length should be 6 cycles/burst or longer. When a disturbance signal is applied to the TSOP18..SS3VA it can still receive the data signal. However the sensitivity is reduced to that level that no unexpected pulses will occure. • DC light (e.g. from tungsten bulb or sunlight), • After each burst a gap time of at least 9 cycles is neccessary. • Continuous signal at 38kHz or at any other frequency, • The data format should not make a continuous signal transmission. There must be a Signal Gap Time (longer than 25ms) at least each 150ms (see Figure A) • Signals from fluorescent lamps (see figure B). • Continuous IR signal (e.g. 1ms burst, 2ms pause) Signal Gap Time 0 20 40 60 80 100 120 140 time [ms] Figure A: Data Signal (Output of IR Receiver) with a Signal Gap Time of 45ms Signal Gap Time 0 2 4 6 8 10 12 14 16 18 20 time [ms] Figure B: Disturbance Signal from Fluorescent Lamp with Signal Gap Time of 7ms (suppressed by TSOP18..SS3V) Document Number 82133 Rev. 2, 13-Jun-00 www.vishay.de • FaxBack +1-408-970-5600 3 (7) TSOP18..SS3VA Vishay Telefunken Typical Characteristics (Tamb = 25_C unless otherwise specified) 100.0 E e min – Threshold Irradiance (mW/m2 ) eE min /eE – Rel.

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.
