TSAL4400

TSAL4400 Vishay Telefunken GaAs/GaAlAs IR Emitting Diode in ø 3 mm (T–1) Package Description TSAL4400 is a high efficiency infrared emitting diode in GaAlAs on GaAs technology, molded in clear, bluegrey tinted plastic packages. In comparison with the standard GaAs on GaAs technology these emitters achieve about 100 % radiant power improvement at a similar wavelength. The forward voltages at low current and at high pulse current roughly correspond to the low values of the standard technology. Therefore these emitters are ideally suitable as high performance replacements of standard emitters. 94 8488 Features D D D D D D D D Extra high radiant power Low forward voltage Suitable for high pulse current operation Standard T–1 (ø 3 mm) package Angle of half intensity ϕ = ± 25° Peak wavelength lp = 940 nm High reliability Good spectral matching to Si photodetectors Applications Infrared remote control units Free air transmission systems Infrared source for optical counters and card readers Absolute Maximum Ratings Tamb = 25_C Parameter Reverse Voltage Forward Current Peak Forward Current Surge Forward Current Power Dissipation Junction Temperature Operating Temperature Range Storage Temperature Range Soldering Temperature Thermal Resistance Junction/Ambient Test Conditions Symbol VR IF IFM IFSM PV Tj Tamb Tstg Tsd RthJA Value 5 100 200 1.5 210 100 –55...+100 –55...+100 260 350 Unit V mA mA A mW °C °C °C °C K/W tp/T = 0.5, tp = 100 ms tp = 100 ms t x 5sec, 2 mm from case Document Number 81006 Rev. 3, 20-May-99 www.vishay.de • FaxBack +1-408-970-5600 1 (5) TSAL4400 Vishay Telefunken Basic Characteristics Tamb = 25_C Parameter Forward Voltage g Temp.

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.
