High voltage ESD protection diodes target high brightness LEDs

California Micro Device CM1753 CM1754

California Micro Devices launches the LuxGuard ESD protection diodes, offering a small form factor and a 50V breakdown voltage for high power and high brightness lighting applications.

CAMBRIDGE, UK — California Micro Devices launches the LuxGuard ESD protection diodes, offering a small form factor and a 50V breakdown voltage for high power and high brightness lighting applications.
The LuxGuard CM1753 and CM1754 devices feature a 50V breakdown voltage specification and deliver a robust 8kV human body model (HBM) ESD protection with low input capacitance for high power, high efficacy HBLED lighting applications.

Designed as silicon based side mount ESD protectors, the CM1753 is built for P-up common cathode configurations and the CM1754 provides identical protection for N-up common anode configurations.
Their tiny form factor enables them to be used in all applications, including existing HBLED lamp modules with the number of LEDs in the string ranging from 1 to 15. The LuxGuard family of products for HBLEDs include silicon sub mounts 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 due to thermal expansion coefficient differences between the LED and the lead frame, while the option of an aluminium top coat provides improved reflectivity.

California Micro Devices 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 are offered in a die form and can be easily integrated into existing or new HBLED lamp modules. Samples are available now.
