Vishay Releases Industry’s First High-Intensity Power SMD LEDs in CLCC6 Ceramic Package With Low Heat Dissipation and Optical Efficiency up to 35 lm/W


Vishay Intertechnology, Inc. released the industry’s first series of high-intensity yellow, amber, and white power SMD LEDs in the CLCC6 ceramic package. The VLMx61 series offers a very low thermal resistance and high optical power for thermal-sensitive applications.

The CLCC6 ceramic package of the VLMK61, VLMY61, and VLMW61 devices allows the additional current drive for a maximum light output while maintaining a high service life of up to 50,000 hours. Its high-efficiency heat dissipation makes the CLCC6 the ideal light source for clustered or matrix designs where the cumulative heat is a key consideration.

The new LEDs in the VLMx61 series are optimized for backlighting and illumination in automotive and transport, consumer, and general applications. Typical end products include handheld mobile devices; traffic lights; household appliances, such as washer, dryers, and refrigerators; and exterior automotive lighting, such as turn and brake lights.

All devices in the series offer a 60°half-intensity angle and are compatible with IR-reflow solder processes, in accordance with CECC 00802 and J-STD-020C. Preconditioned according to JEDEC Level 4a standards, the CLCC6 package is lead (Pb)-free and RoHS-compliant, and is Automotive-qualified AEC-Q101.
