5977721207

Overview

The Dialight 5977721207F is a dual-color surface-mount LED component belonging to the microLED series. It features independent green and yellow emitters housed in a 4-PLCC package with dimensions of 3.10mm length, 2.80mm width, and a maximum height of 2.05mm. The device utilizes a clear, circular lens with a flat top and a 2.39mm diameter. Electrical characteristics include a forward voltage of 2.1V for the green emitter and 1.8V for the yellow emitter, both tested at 20mA. Optical performance specifies a peak wavelength of 565nm for green and 585nm for yellow, with a main wavelength of 570nm and 590nm respectively. Light intensity is rated at 16mcd for both colors, supported by a 120-degree viewing angle.

Feature Summary

• Dual-color configuration providing independent green and yellow light output within a single compact surface-mount package
• Clear optical lens design ensures high transparency and defined beam distribution without diffusion effects
• Standardized 4-PLCC footprint facilitates automated placement and integration into dense circuit board layouts

Applications

• Status indication on electronic control panels
• Signal lights for industrial machinery interfaces
• Visual alerts in automotive instrumentation clusters
• Indicator lamps for consumer appliance user interfaces

Procurement Notes

Verify the specific ordering suffix 'F' to confirm the presence of lead-free plating and RoHS compliance status. Confirm that the 4-PLCC package dimensions match the target PCB land pattern. Check moisture sensitivity level requirements against available storage time limits. Ensure the forward current ratings align with the driving circuit capabilities to prevent thermal stress or insufficient brightness during operation.

Selection Notes

Select this component when a dual-color status indicator is required in a space-constrained area. The 4-PLCC package offers a balance between thermal dissipation and board space efficiency compared to larger through-hole alternatives. Consider the 120-degree viewing angle for visibility requirements. Evaluate the 16mcd intensity against ambient lighting conditions to ensure adequate signal visibility for end-users in the intended application environment.
