C503B-GAS-CC0D0782

Overview

The C503B-GAS-CC0D0782 is a high-power LED emitter from Cree's XLamp series, designed for general illumination and commercial lighting applications. This specific component features a green phosphor conversion package that delivers a correlated color temperature of approximately 4000K to 5000K, providing neutral white light output. The device utilizes a ceramic substrate with silver epoxy die attach technology to ensure robust thermal management and long-term reliability under continuous operation. Electrical characteristics typically include a forward voltage range suitable for standard constant current drivers, with nominal operating currents defined by the manufacturer's binning specifications. The optical performance is characterized by high luminous efficacy and consistent chromaticity coordinates, meeting ANSI standards for color consistency across production batches.

Feature Summary

• Utilizes advanced ceramic substrate construction for superior thermal dissipation and mechanical stability compared to traditional PCB-based packages.
• Employs proprietary phosphor conversion technology to achieve precise color rendering and stable correlated color temperature over extended operational lifetimes.
• Engineered with silver epoxy die attach methods to enhance heat transfer efficiency from the LED junction to the mounting surface.

Applications

• Commercial ceiling-mounted fluorescent replacements
• High-bay industrial lighting fixtures
• Outdoor street lighting luminaires

Procurement Notes

Verify the specific binning codes for luminous flux and chromaticity coordinates against your design requirements before ordering. Ensure that the thermal interface material selected matches the recommended mounting torque and surface finish specifications provided in the official datasheet. Confirm driver compatibility with the forward voltage range at your intended operating current to prevent premature lumen depreciation or thermal runaway issues during system integration.

Selection Notes

Select this component when high thermal conductivity and reliable performance in enclosed fixture environments are required. Consider the specific color temperature binning options available to match architectural lighting design goals. Evaluate the total system thermal resistance to ensure the junction temperature remains within safe operating limits under worst-case ambient conditions. Compare efficacy values against alternative emitters to optimize overall luminaire efficiency and energy consumption targets.

Part Context

This part belongs to the XLamp C503B family, which represents a generation of mid-power to high-power LEDs optimized for retrofitting existing fluorescent fixtures. The series is known for its standardized footprint and pin configuration, facilitating direct replacement designs. It serves as a core light source for manufacturers transitioning from traditional lighting technologies to solid-state solutions while maintaining similar form factors and thermal management strategies.

Replacement Considerations

Direct replacements must match the physical dimensions and pinout configuration of the original component. Verify that substitute parts offer equivalent or superior thermal resistance characteristics to maintain junction temperature limits. Check for compatible forward voltage ranges to ensure seamless integration with existing driver electronics without requiring circuit modifications.
