5977752002F

Overview

The Dialight 5977752002F is a bi-color surface-mount LED indicator featuring green and red elements within a compact 4-PLCC package. It emits at peak wavelengths of 525nm for green and 625nm for red, with dominant wavelengths of 525nm and 625nm respectively. The device operates with a forward voltage of 3.15V for the green element and 2V for the red element, tested at 20mA each. Luminous intensity reaches 850mcd for green and 350mcd for red. It offers a wide 120-degree viewing angle with a clear, non-diffused lens.

Feature Summary

• Bi-color configuration providing independent green and red light output in a single component
• High luminous intensity suitable for clear visibility in panel applications
• Wide 120-degree viewing angle ensures broad signal visibility
• Standard 4-SMD J-leads facilitate automated surface-mount assembly

Applications

• Panel-mounted status indicators
• Electronic equipment power and fault signaling
• Industrial control interface displays
• Consumer appliance operational feedback

Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm that the 4-PLCC package dimensions align with existing PCB footprints. Ensure thermal management requirements are met during soldering processes. Validate compliance with RoHS3 standards if required by project specifications. Check for any recent Product Change Notices affecting manufacturing sites or materials.

Selection Notes

Choose this part when space constraints require a dual-color indicator in a small footprint. Compare forward voltage drops against available drive circuitry to ensure proper current limiting. Consider the 120-degree viewing angle relative to operator position. Evaluate the specific wavelength requirements against ambient lighting conditions. Verify that the non-diffused lens type meets visibility needs without additional optics.

Part Context

This component belongs to the Dialight microLED series, designed for high-density surface-mount applications. It provides a compact solution for multi-state indication where board real estate is limited. The 4-PLCC form factor is standard for many SMD LED families, allowing compatibility with common pick-and-place equipment and reflow profiles.
