Product Details Supplier Info More products

California Micro Devices has introduced the latest products in the Luxguard range of turnkey solutions.

These solutions are suitable for the electrostatic discharge (ESD) protection and thermal management of high-power, high-brightness light-emitting-diode (HBLED) lighting applications.

The new Luxguard CM1753 and CM1754 products feature a 50V breakdown voltage specification and deliver an 8kV human-body model (HBM) of ESD protection with low input capacitance for high-power HBLED lighting applications.

Designed as silicon-based side-mount ESD protectors, the CM1753 is designed for P-up common cathode configurations and the CM1754 provides identical protection for N-up common anode configurations.

A tiny form factor enables the devices to be used in existing HBLED lamp modules, with the number of LEDs in the string ranging from one to 15.

Luxguard products for HBLEDs include silicon submounts and side-mount TVS diodes.

Luxguard submounts provide integrated ESD protection at levels exceeding 15kV HBM.

The submount also helps to cushion the LED from stress as a result of thermal expansion coefficient differences between the LED and the lead frame, while the option of an aluminium 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 30kV HBM.

The Luxguard CM1753 and CM1754 devices are offered in a die form and can be integrated into existing or new HBLED lamp modules.

Samples are available now for the CM1753 and theCM1754, with full production in the second quarter of 2010.
