C503B-GAS-CB0F0791

Overview

The C503B-GAS-CB0F0791 is a green light-emitting diode manufactured by Cree LED, designed for through-hole mounting in the 5 mm (T-1 3/4) package. It emits at a dominant wavelength of 527 nm with a narrow viewing angle of 15 degrees. The component operates with a forward voltage of 4 V and a maximum forward current of 30 mA. Luminous intensity ranges from 16,800 to 90,500 mcd. Maximum power dissipation is rated at 120 mW. The lens is clear and colorless, ensuring high visibility.

Feature Summary

• Provides superior light output for excellent readability in sunlight
• Ensures extremely stable light output over long periods of time
• Constructed with advanced optical-grade epoxy for high temperature resistance
• Offers dependable performance in outdoor signal and sign applications

Applications

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

Procurement Notes

Verify the specific suffix CB0F0791 against official Cree documentation to confirm exact luminous intensity binning and packaging configuration. Ensure compatibility with existing PCB layouts for 5 mm radial leads. Confirm RoHS compliance status via the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this model when high-intensity green indication is required with a focused beam pattern. The 15-degree viewing angle distinguishes it from wider-angle variants like the GCN series. Consider the 4 V forward voltage drop for circuit design. Verify thermal management requirements given the 120 mW power dissipation limit in enclosed environments.

Part Context

This component belongs to the Cree 5-mm Blue and Green Round LED family. It shares mechanical dimensions with other C503B variants but differs in optical characteristics. The GAS designation indicates a green emission with a 15-degree viewing angle. This series is engineered for durability in harsh outdoor environments compared to standard indicator LEDs.

Replacement Considerations

C503B-GAN-CB0C0891 offers similar green emission but with a 30-degree viewing angle. C503B-GCS provides a wider beam profile. Verify that the alternative part number matches the required luminous intensity range and physical lead spacing before substitution.
