ON Semiconductor’s new CM1771 is a 100 V back-to-back electrostatic discharge (ESD) protection device that prolongs operation of HBLED lamp modules. It features a 100 V breakdown voltage and, as a member of the LuxGuard family of turnkey solutions for ESD protection in high-voltage circuits, it is suitable for general illumination, signage, automotive and commercial lighting applications.
To ensure emerging opportunities for HBLED technology are realised, 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 small die that can be integrated into a wide selection of HBLED lamp modules. The CM1771 is offered as a 440 x 440 μm die.
