5977721107F

Overview

The Dialight 5977721107F is a discontinued dual-color surface-mount LED featuring green and yellow emitters in a 4-SMD, no-lead package. It operates with a typical forward voltage of 2V for the green element and 2.1V for the yellow element at a test current of 20mA. The device emits light at peak wavelengths of 565nm (green) and 585nm (yellow). Optical performance includes a viewing angle of 170 degrees, with luminous intensities of 12mcd for green and 8mcd for yellow. The component utilizes a colorless, flat-top rectangular lens with dimensions of 3.00mm length by 2.54mm width.

Feature Summary

Dual-color configuration providing independent green and yellow emission from a single compact package
Wide 170-degree viewing angle ensures broad visibility for indicator applications
Water-clear, colorless flat-top lens design maintains high optical transparency

Applications

Multi-state status indicators on electronic circuit boards
Visual signaling devices requiring distinct color coding
Panel mount instrumentation displays

Procurement Notes

This component is officially obsolete and no longer manufactured. Verification of availability must focus on surplus stock or secondary market sources rather than direct manufacturer orders. Confirm that replacement alternatives meet all electrical and mechanical specifications before integration into new designs.

Selection Notes

Designers should evaluate the specific forward voltage requirements for both color channels to ensure proper driver circuit compatibility. The wide viewing angle and moderate intensity suit general indication tasks but may require optical adjustment for long-distance visibility. Verify that the 4-SMD footprint aligns with existing PCB layout constraints.

Part Context

Part of the Dialight microLED series, this component represents a standard dual-color SMD solution. It was designed for space-constrained applications requiring multiple signal states without increasing board area. The 4-SMD form factor allows for automated assembly processes common in modern electronics manufacturing.
