California Micro Devices Announces LuxGuard(TM), a Family of High Brightness LED

Protection Devices

MILPITAS, Calif., Mar. 16 /PRNewswire-AsiaNet/ --

             Ideal for High Power and Ultra High Brightness Lighting


    California Micro Devices (Nasdaq: CAMD) 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, vice president 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 Options

    CMD 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


    - A variety of sub mount and TVS die sizes to accommodate different HB

      LED applications;

    - Various metallization options to meet most manufacturing


    The LuxGuard Advantage

    With 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. To find out
