| VISHAY LH1546AD/ ADF/ ADFTR Vishay Semiconductors 1 Form A Solid State Relay Features * * * * * * * * * * Current Limit Protection Isolation Test Voltage 5300 VRMS Typical RON 28 Load Voltage 350 V Load Current 120 mA High Surge Capability Linear, AC/DC Operation Clean Bounce Free Switching Low Power Consumption High Reliability Monolithic Receptor A1 K2 4S S i179058 S' 3 S1 * SMT Lead Available on Tape and Reel Description The LH1546AD (4 Pin DIP) is robust, ideal for telecom and ground fault applications. It is a SPST normally open switch (1 Form A) that replaces electromechanical relays in many applications. It is constructed using a GaAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated BCDMOS technology, is comprised of a photodiode array, switch control circuitry and MOSFET switches. In addition, it employs current-limiting circuitry which meets FCC 68.302 and other regulatory voltage surge requirements when overvoltage protection is provided. Agency Approvals * UL - File No. E52744 * BSI/BABT Cert. No. 7980 Applications General Telecom Switching - On/off Hook Control - Ring Delay - Dial Pulse - Ground Start - Ground Fault Protection Instrumentation Industrial Controls See "Solid State Relays" (Application Note 56) Order Information Part LH1546AD LH1546ADF LH1546ADFTR Tubes, DIP-4 Gullwing, Tubes, SMD-4 Gullwing, Tape and Reel, SMD-4 Remarks Absolute Maximum Ratings, Tamb = 25 C Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device.

Meet all present and future national and international statutory requirements. VISHAY 2. Regularly and continuously improve the performance of our products, processes, distribution and operatingsystems 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.
