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

MILPITAS, California - Ideal for High Power and Ultra High Brightness Lighting Applications

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 US$1.5 billion in 2009 to US$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
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 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
