CLM4B-GKC-CYAYB793

Overview

The CLM4B-GKC-CYAYB793 is a single-color green surface-mount LED from the Cree LED PLCC4 family. It features a standard PLCC-4 package with dimensions of 3.2 mm x 2.7 mm and a maximum height of 1.95 mm. The component emits green light at a typical dominant wavelength of 527 nm. It operates with a forward current of 20 mA and a forward voltage of approximately 3.1 V. The device provides a luminous intensity range of 1400 to 3550 mcd and offers a wide viewing angle of 120 degrees. It is lead-free and RoHS compliant.

Feature Summary

• High-reliability performance designed for diverse environmental conditions
• Flat-top emitting surface facilitates mating with light pipes
• Wide 120-degree viewing angle suitable for architectural applications

Applications

• Channel letter lighting
• Architectural lighting
• Light strips

Procurement Notes

Verify the specific suffix CYAYB793 against official datasheets to confirm binning parameters, as Cree utilizes complex coding for wavelength and intensity selection. Ensure compatibility with standard PLCC-4 reflow profiles. Confirm that the requested quantity aligns with manufacturer packaging standards, typically available in cut tape or reel formats depending on volume requirements.

Selection Notes

Select this component when high-intensity green illumination is required within a compact PLCC-4 footprint. The 120-degree viewing angle makes it suitable for applications requiring broad light distribution. Consider the flat-top lens design if integration with light piping systems is necessary. Verify thermal management requirements based on the 20 mA operating current and power dissipation characteristics.

Part Context

This part belongs to the Cree LED PLCC4 series, which are industry-standard surface-mount LEDs. The series is characterized by high reliability and suitability for architectural lighting. The PLCC4 package allows for automated assembly and provides a robust mechanical structure for various lighting modules.

Replacement Considerations

Direct replacements within the same series include CLM4B-BKW (Blue) or other color variants in the PLCC4 package. Cross-family replacements require matching the PLCC-4 footprint, electrical ratings, and optical intensity. Verify that alternative components support the required 120-degree viewing angle and flat-top lens geometry.
