5977781307F

Overview

The Dialight 5977781307F is a dual-color surface-mount LED featuring blue and red emitters in a PLCC-4 package. It operates with a forward current of 20 mA per color and a forward voltage of approximately 3 V for the blue element and 2.1 V for the red element. The device emits light at wavelengths of 470 nm (blue) and 626 nm (red). It offers a viewing angle of 120 degrees and utilizes a clear lens for optimal visibility.

Feature Summary

• Dual-color configuration combining blue and red LEDs within a single compact package
• Clear lens design ensures high transparency and distinct color separation
• Wide 120-degree viewing angle provides broad visibility for indicator applications

Applications

• Status indication on electronic circuit boards
• Power supply status indicators
• Multi-state signaling in industrial control panels

Procurement Notes

Verify the specific datasheet version to confirm exact forward voltage tolerances and luminous intensity ranges, as these parameters can vary between manufacturing batches. Ensure compatibility with standard PLCC-4 footprint dimensions during PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to final component selection.

Selection Notes

Select this component when space-constrained designs require two distinct signal colors without increasing board area. The PLCC-4 form factor allows for automated pick-and-place assembly. Consider thermal management requirements if multiple units are densely packed, although power dissipation remains low for standard indicator duties.

Part Context

This part belongs to the Dialight 597 series of MicroLEDs, which focuses on small-footprint surface-mount technology solutions. The series provides various color combinations and package sizes to meet diverse lighting needs. The 5977781307F specifically addresses the need for dual-color signaling in compact electronic assemblies.

Replacement Considerations

Direct substitutes include other PLCC-4 dual-color LEDs from manufacturers such as Kingbright or Everlight, provided they match the 470nm/626nm wavelength combination and mechanical dimensions. Verify pinout compatibility and electrical characteristics before substitution.
