C5SMF-BJN-CT34Q3T1

Overview

The C5SMF-BJN-CT34Q3T1 is a standard through-hole LED from the Screen Master family, manufactured by Cree LED. It features an oval lens shape with dimensions of 5.1 mm x 3.7 mm and a height of 7.8 mm maximum. The component emits blue light at a dominant wavelength of 470 nm with a forward voltage of 3.4 V at a test current of 20 mA. It offers a luminous intensity of 1500 mcd and a viewing angle of 70 degrees by 35 degrees. The device operates within a temperature range of -40°C to +85°C and is supplied in bulk packaging.

Feature Summary

• Oval radiation pattern designed for wide-angle visibility
• High luminous intensity suitable for outdoor signage
• Advanced optical-grade epoxy encapsulation for moisture resistance

Applications

• Variable-message signs (VMS)
• Passenger-information displays
• Electronic traffic signals

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and binning. Ensure compliance with RoHS directives as indicated in the product specifications. Cross-reference the part number with official distributor catalogs to validate availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a wide viewing angle and high brightness are required for ambient light conditions. The oval lens geometry provides superior readability compared to round LEDs in certain mounting orientations. Consider the 3.4 V forward voltage drop for circuit design compatibility with standard drive currents.

Part Context

This part belongs to the Screen Master 5-mm Oval LED series, which expands Cree's portfolio of indicator LEDs. The series is engineered specifically for applications requiring high visibility and durability. It complements other variants in the family that offer different colors and intensities while maintaining consistent physical dimensions.

Replacement Considerations

Direct substitutes include other C5SMF-BJN variants with different suffixes for packaging or binning differences. Verify mechanical footprint compatibility when replacing with generic 5mm oval LEDs.
