C4SMM-GJY-CT34Q7D1

Overview

The C4SMM-GJY-CT34Q7D1 is a single-color green light-emitting diode manufactured by Cree LED. It features a 4-mm oval lens with a dome shape and clear transparency. The component operates at a peak wavelength of 527 nm, providing a luminous intensity range of 1310 to 2130 mcd. Electrical characteristics include a forward voltage of 2.9 V and a maximum power rating of 140 mW. Designed for through-hole mounting, it supports an operating temperature up to +105°C, ensuring reliability in high-temperature environments.

Feature Summary

• High-temperature operation capability up to +105°C
• Oval dome lens design for specific beam distribution
• Reliable performance matching standard variant electrical characteristics

Applications

• Through-hole electronic applications
• General illumination purposes
• Indicator lighting in consumer electronics

Procurement Notes

Verify the exact binning codes for luminous intensity and wavelength when ordering, as these parameters vary within the specified ranges. Confirm that the through-hole package dimensions align with your PCB layout requirements. Ensure thermal management strategies account for the +105°C operating limit during system integration.

Selection Notes

Select this component when a green indicator with high brightness and thermal stability is required. The 4-mm oval form factor suits applications needing distinct visual presence. Consider the 2.9 V forward voltage drop for circuit design compatibility. Evaluate the 1310–2130 mcd intensity range against ambient lighting conditions to ensure visibility.

Part Context

This part belongs to the Pro9 LED series from Cree LED, known for enhanced reliability and high-temperature performance. It shares mechanical and electrical traits with standard variants but offers extended operational limits. The C4SMM series utilizes advanced packaging techniques for consistent optical output and durability in demanding electronic assemblies.

Replacement Considerations

Direct substitutes may include other Cree LED green LEDs in the 4-mm oval package family, such as those with similar wavelength and intensity bins. Verify pinout compatibility and forward voltage tolerance before substitution. Cross-reference datasheets for thermal resistance and mounting hole specifications to ensure mechanical interchangeability.
