C5SMF-GJS-CV0Y0791

LED Indication - Discrete Overview

The C5SMF-GJS-CV0Y0791 is a green light-emitting diode from the Cree Screen Master series, designed for through-hole mounting in a 5mm (T-1 3/4) oval package. It features a primary wavelength of 535 nm and an elliptical lens shape with a green tinted appearance. Key electrical parameters include a forward voltage of 4 V and a luminous intensity of 8.2 cd. The component utilizes two pins for connection and is engineered to provide high visibility in signage applications.

LED Indication - Discrete Feature Summary

• Features an oval-shaped radiation pattern specifically optimized for wide viewing angles in variable-message signs.
• Constructed with a green-tinted elliptical lens to enhance contrast and legibility in passenger-information displays.
• Delivers high luminous intensity suitable for demanding outdoor and indoor visual signaling environments.

LED Indication - Discrete Applications

• Variable-message traffic signs
• Passenger-information display systems
• Public transit status indicators

LED Indication - Discrete Procurement Notes

Verify the specific suffix CV0Y0791 against official Cree documentation to confirm exact binning and optical characteristics. Ensure compatibility with existing PCB footprints for T-1 3/4 oval packages. Confirm RoHS compliance status through current manufacturer declarations before integration into final assemblies.

LED Indication - Discrete Selection Notes

Select this component when a narrow spectral peak at 535 nm is required for optimal human eye sensitivity in daylight conditions. The oval form factor provides superior horizontal visibility compared to standard round LEDs. Consider the 4 V forward voltage drop when designing series resistor networks for constant current drive circuits.

LED Indication - Discrete Part Context

This part belongs to the Screen Master family of 5-mm oval LEDs developed by Cree LED. These devices are distinct from standard indicator LEDs due to their specialized optical engineering for large-format displays. The series prioritizes brightness uniformity and long-term reliability for critical information signage infrastructure.

LED Indication - Discrete Replacement Considerations

Direct substitutes within the same Screen Master oval family may exist with different intensity bins or wavelength variations. Verify mechanical dimensions and pin spacing to ensure interchangeability without modifying the host circuit board layout.

LED Indication - Discrete FAQ

What is the primary advantage of the oval lens shape over a round lens?

The oval lens creates a wider horizontal viewing angle, which is essential for readability on large variable-message signs where observers approach from various lateral positions.

Is this LED suitable for automotive exterior lighting?

No, official specifications indicate it does not meet automotive standards such as AEC-Q101, making it intended for general signage rather than vehicle-mounted applications.
