Relay requires a minimal amount of LED drive current to operate, making relay ideal for battery powered and power consumption sensitive applications. The relay is constructed using a GaAlAs 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, the relay employs current-limiting circuitry enabling it to pass FCC 68.302 and other regulatory surge requirements when overvoltage protection is provided.

An extended clamp condition, which increases relay temperature, decreases the currentlimit value, resulting in a current fold back characteristic. When the overload is removed, the relay resumes its normal ON-resistance characteristic. In a 1 Form A relay, to turn the relay on, forward current is applied to the LED. The amount of current applied determines the amount of light produced for the photodiode array. This photodiode array develops a drive voltage for the MOSFET switch outputs. For high temperature or high-load current operations, more LED current is required. 120 Load Current (mA) 100 2.5 mA 80 2.0 mA 60 1.5 mA 40 1.0 mA 20 ILED = 0.3 mA 0 -40 -20 0 20 40 60 80 Temperature (°C) ilh1525acd_00 Figure 1.

Typical AC/DC ON Characteristics Functional Description Figure 2 shows the switch characteristics of the relay. The relay exhibits an ON-resistance that is exceptionally linear through the origin and up to the knee current (IK). Beyond IK, the incremental resistance decreases, minimizing internal power dissipation. Overload currents are clamped at ILMT by the internal current-limit circuitry. The current-limiting circuitry exhibits a negative temperature coefficient, thereby Document Number 83824 Rev. 1.3, 26-Oct-03 www.vishay.com 3 LH1525ACD/ ACDTR Vishay Semiconductors Package Dimensions in Inches (mm) .336 ±.010 (8.53 ±.25) .291 ±.010 (7.39 ±.25) .015 ±.002 (.38 ±.05) .042 (1.07) ref.

Meet all present and future national and international statutory requirements. 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.
