Due to the different clamping levels in forward and reverse direction the clamping behavior is Bidirectional and Asymmetric (BiAs). L1IN 4 3 5 2 6 1 L1OUT L2IN L2OUT 19500 19420 The 2 independent EMI-Filter are placed between Pin 1 & Pin 6, and Pin 3 & Pin 4 They all are connected to the common ground Pin no. 2. Pin no. 5 is not connected. Each filter is symmetrical so that all ports (Pin 1, 3, 4 & 6) can be used as Input or Output. 19421 Circuit diagram of one EMI-Filter-Channel RS Output Input C C Ground 19467 Each filter is symmetrical so that both ports can be used as Input or Output. www.vishay.com 4 Document Number 84772 Rev. 1.2, 15-Aug-05 VEMI255A-HS3 Vishay Semiconductors Package dimensions in mm (inches) 1 (0.039) 0.6 (0.023) 2 3 6 5 4 1 (0.039) 0.15 (0.006) 0.7 (0.027) 0.5 (0.020) 1 0.25 (0.010) 0.25 (0.010) (6x) ISO Method E 1.6 (0.062) 1.6 (0.062) Top View 18058 Document Number 84772 Rev. 1.2, 15-Aug-05 www.vishay.com 5 VESD05A8-HN2 Vishay Semiconductors 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.
