California Micro Devices announces LuxGuard family of HB LED protection devices

Date Announced: 16 Mar 2009 MILPITAS, Calif. -- California Micro Devices today announced the availability of the LuxGuard family of turnkey solutions for ESD (electrostatic discharge) protection and thermal management for high power, ultra high brightness LED (light emitting diode) lighting applications.The LuxGuard family of protection solutions includes both LED submounts that deliver robust ESD protection and enhanced thermal management capabilities and side mounts which offer superior ESD protection for customers that utilize ceramic submounts. A pioneer in the development of ESD protection circuits for high power ultra high brightness (UHB) LED applications, CMD has shipped more than 300 million units to customers since 2001. Leveraging a significant foundation of application knowledge, CMD's LuxGuard solutions are being offered with popular design options that enable customers to optimize the products for seamless integration in the UHB LED lighting module. The market for high power, UHB LEDs has expanded beyond traditional market segments such as status and alphanumeric display markets into a wider range of lighting applications, including handset display and keypad illumination, automotive, signage, residential and commercial lighting."Improvements in performance, efficiency, cost and reliability for UHB LEDs have been important contributing factors to their rapid penetration, accounting for over 15 percent of the total market in 2008, up from 10 percent in 2007," said Jagdish Rebello, Ph.D. Principal Analyst for LED markets at iSuppli Corporation. "iSuppli forecasts the revenue for UHB LEDs to increase from $1.5 billion in 2009 to $3.9 billion in 2012 at a compound annual growth rate of 47 percent.""High power LEDs are more ESD sensitive than their lower power counterparts, and require external ESD protection for enhanced reliability. Improved thermal management in a silicon based submount at a lower cost than more expensive ceramic submounts creates significant customer value," said Kyle Baker, VP of marketing for California Micro Devices. "LuxGuard submounts and diodes address these exacting requirements for ESD performance and thermal management for UHB LEDs."LuxGuard Design OptionsCMD offers two types of LuxGuard products for HB LEDs: silicon submounts and side mount TVS diodes. LuxGuard sub mounts provide integrated ESD protection at levels exceeding 15kV HBM (Human Body Model). The submount also helps to cushion the LED from stress due to thermal expansion coefficient differences between the LED and the lead frame, while the option of an aluminum top coat provides improved reflectivity. CMD also offers TVS diodes mounted next to the LED die within the LED fixture. ESD ratings vary based on die size, and are typically between 8kV and 15kV HBM.CMD offers a wide variety of product options, including:--Single direction or bidirectional TVS solutions; --Varying breakdown voltage levels to support single or multi-LED products; --A variety of sub mount and TVS die sizes to accommodate different HB LED applications; --Various metallization options to meet most manufacturing requirements. The LuxGuard AdvantageWith a number of design options, LuxGuard products leverage CMD's significant process, design and application knowledge and provide customers superior value of application specific solution, while enjoying the lower costs associated with higher volume, general customer solutions.About California Micro Devices CorporationCalifornia Micro Devices Corporation is a leading supplier of application specific analog and mixed signal semiconductor products for the mobile handset, digital consumer electronics and personal computer markets.
