High Speed Optocoupler, 00 kbd, Low nput Current, High Gain i79070 NC A C NC 8 7 V CC V B V 0 GND FEATURES ndustry Standard SOC-8 Surface Mountable Package High Current Transfer Ratio, 800 % Low nput Current, 0. ma High Output Current, 0 ma solation Test Voltage, 000 V RMS TTL Compatible Output, L = 0. V Adjustable Bandwidth-Access to Base Lead (Pb)-free component Component in accordance to RoHS 00/9/EC and WEEE 00/9/EC DESCRPTON Very high current ratio together with 000 V RMS isolation are achieved by coupling an LED with an integrated high gain photo detector in a SOC-8 package. Separate pins for the photo diode and output stage enable TTL compatible saturation voltages with high speed operation. Photodarlington operation is achieved by tying the V CC and terminals together. Access to the base terminal allows adjustment to the gain bandwidth. The SFH8T is ideal for TTL applications since the 00 % minimum current transfer ratio with an LED current of. ma enables operation with one unit loadin and one unit load-out with a. kω pull-up resistor. The SFH9T is best suited for low power logic applications involving CMOS and low power TTL. A 00 % current transfer ratio with only 0. ma of LED current is guaranteed from 0 C to 70 C. Caution: Due to the small geometries of this device, it should be handled with Electrostatic Discharge (ESD) precautions. Proper grounding would prevent damage further and/or degradation which may be induced by ESD.

Ozone Depleting Substances Policy Statement t is the policy of Vishay Semiconductor GmbH to. Meet all present and future national and international statutory requirements.. 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. t 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 (987) and its London Amendments (990) 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.. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively. Class and ozone depleting substances in the Clean Air Act Amendments of 990 by the Environmental Protection Agency (EPA) in the USA. Council Decision 88/0/EEC and 9/90/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 products for any unintended or unauthorized application, the buyer shall indemnify 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.
