Next Generation ESD Protection for High Power HBLEDs

ON Semiconductor’s new CM1771 is a 100 V back-to-back electrostatic discharge protection device that prolongs operation of HBLED lamp modules. It is the industry’s first ESD protection solution for HBLED applications to feature a 100 V breakdown voltage. The CM1771 is a member of the innovative LuxGuard family of turnkey solutions for ESD protection in high voltage circuits and is ideal for general illumination, signage, automotive and commercial lighting applications.

To ensure emerging opportunities for HBLED technology are realized, emitter manufacturers need to be sure their devices are not left vulnerable to damage from ESD strikes. Delivering protection at high breakdown voltages presents a new challenge in dissipating higher levels of power when an ESD strike occurs while maintaining acceptably low dynamic clamping voltages. The proprietary side mount arrangement featured in the CM1771 delivers robust, symmetrical ESD protection in a very small, cost-effective die that can be easily integrated into a wide selection of HBLED lamp modules.

The CM1771 is offered as a 440 µm x 440 µm die. Pricing for these devices is $0.02 per unit in 100,000 unit quantities
