AA4040ZGS

LED Indication - Discrete Overview

The AA4040ZGS is a single-color surface-mount LED manufactured by Kingbright, featuring a green InGaN emitter with a peak wavelength of 525 nm. It utilizes a water-clear dome lens housed in a PLCC-2 (2-SMD, Right Angle) package measuring 4.0 mm x 3.6 mm x 4.0 mm. The component operates at a forward current of 20 mA with a typical forward voltage of 3.3 V and a power rating of 102.5 mW. It delivers a luminous intensity of 800 mcd with a viewing angle of 90 degrees. The device supports operation within a temperature range of -40°C to +85°C and carries MSL level 4 moisture sensitivity.

LED Indication - Discrete Feature Summary

• Water-clear dome lens design for optimized light transmission

LED Indication - Discrete Applications

• Consumer electronics status indicators
• Industrial control panel signaling
• Medical device operational feedback

LED Indication - Discrete Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to procurement, as manufacturing updates may occur. Confirm moisture sensitivity handling requirements during storage and reflow soldering processes. Ensure compatibility with standard SMT assembly equipment for right-angle packages. Cross-reference ordering suffixes if alternative packaging options are required for production lines.

LED Indication - Discrete Selection Notes

Select this component when a right-angle form factor is necessary for board stacking or limited vertical clearance. The 3.3 V forward voltage aligns with standard logic-level driving circuits. Consider the 90-degree viewing angle for direct visibility applications. Evaluate thermal management needs given the 102.5 mW power dissipation in dense assemblies.

LED Indication - Discrete Part Context

The AA4040ZGS belongs to Kingbright's AA4040 series of second-generation SMD LEDs, designed for improved material durability and electrical reliability. This series targets dense system designs requiring robust performance. The right-angle variant specifically addresses layout constraints where standard top-emitting components cannot fit.

LED Indication - Discrete Replacement Considerations

The KA-4040SURSK is listed as an alias for the AA4040SURSK model, not the ZGS variant. No public confirmed substitute part numbers are available for the AA4040ZGS in the provided documentation.
