AA4040SGS

Overview

The AA4040SGS is a single-color surface-mount LED manufactured by Kingbright, emitting super bright green light at a peak wavelength of 568 nm. Housed in a PLCC-2 package with dimensions of 4.0 mm x 4.0 mm x 4.0 mm, it features a water-clear dome lens and a 2.4 mm viewing area. The device operates at a forward current of 20 mA with a forward voltage of 2.1 V to 2.2 V, delivering an optical intensity of 30 mcd. It supports a wide operating temperature range from -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Super bright green emission utilizing Gallium Phosphide technology
• Water-clear dome lens for optimized light transmission
• Compatible with standard SMT assembly and solder processes

Applications

• Backlighting applications
• Panel indicator lights
• Electronic status indication

Procurement Notes

Verify moisture sensitivity level (MSL) classification prior to storage and handling, as the component is sensitive to humidity. Confirm that the supplier provides documentation confirming RoHS compliance. Ensure the ordering suffix matches the required tape and reel packaging format. Validate the specific binning for luminous intensity if precise brightness consistency is required for the application.

Selection Notes

Select this component when a compact 4.0x4.0mm form factor is required for green indication. Consider the 120-degree viewing angle for visibility requirements. Evaluate the 2.1V forward voltage drop against the system power budget. Ensure the PCB footprint matches the PLCC-2 package dimensions for proper mechanical fit.

Part Context

This part belongs to the AA4040 series of surface-mount LEDs from Kingbright. The series offers various color options including red, orange, and green within a standardized 4.0x4.0mm PLCC-2 package. This specific model represents the green variant, sharing common mechanical dimensions and mounting characteristics with other colors in the family while differing in optical output specifications.

Replacement Considerations

Direct substitutes include other Kingbright AA4040 series variants such as AA4040SURSK or AA4040SECK, provided the color difference is acceptable. Verify pin compatibility and thermal characteristics before substitution.
