C503B-GAS-CB0C0781

Overview

The C503B-GAS-CB0C0781 is a single-color green LED from the Cree LED series, housed in a 5 mm (T-1 3/4) through-hole package. It features a dome-shaped lens with a clear tint and emits light at a dominant wavelength of 527 nm. The component operates with a forward current of 20 mA and a forward voltage of 3.2 V, dissipating up to 120 mW. It provides a luminous intensity of 38,000 mcd with a narrow viewing angle of 15 degrees. The device functions within a temperature range of -40°C to +95°C and complies with RoHS standards.

Feature Summary

• High-intensity green emission optimized for outdoor readability
• Advanced optical-grade epoxy construction for moisture resistance
• Narrow 15-degree beam angle for directional signaling
• Through-hole radial mount design for standard PCB integration

Applications

• Electronic Signs & Signals (ESS)
• Motorway Signs
• Variable-Message Sign (VMS)
• Advertising Signs
• Petrol Signs

Procurement Notes

Verify component authenticity against official Cree LED datasheets before integration. Confirm that the specific suffix CB0C0781 matches required electrical parameters such as 527 nm wavelength and 38,000 mcd intensity. Ensure sourcing channels provide valid RoHS compliance documentation. Check for any product change notifications or end-of-life status updates prior to final procurement decisions.

Selection Notes

Select this component when high visibility in bright ambient conditions is required due to its superior light output. The 15-degree viewing angle makes it suitable for applications needing focused illumination rather than wide-area lighting. Consider the 5 mm T-1 3/4 package dimensions for mechanical fitment. Evaluate thermal management requirements given the 120 mW power dissipation rating during continuous operation.

Part Context

This part belongs to the C503B family of 5-mm blue and green round LEDs designed by Cree LED. The series utilizes advanced optical-grade epoxy to ensure stability under high-temperature and high-moisture environments. These lamps are engineered for dependable performance in demanding outdoor signal and sign applications where long-term reliability is critical.
