AA4040ZGC/G

Overview

The AA4040ZGC/G is a single-color surface-mount LED manufactured by Kingbright, featuring a green emission with a peak wavelength of 515 nm and a dominant wavelength of 525 nm. It utilizes a water-clear lens within a 2-SMD (Boomerang) package measuring 3.60 mm in length, 4.00 mm in width, and a maximum height of 4.00 mm. The component operates at a forward current of 20 mA with a typical forward voltage of 3.3 V. It offers a nominal luminous intensity of 600 mcd and a viewing angle of 90 degrees, designed for reliable performance across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Green light emission with a 515 nm peak wavelength housed in a compact 2-SMD Boomerang package.
• Water-clear dome lens design providing a standardized 90-degree viewing angle for consistent visibility.
• RoHS3 compliant construction ensuring environmental safety and regulatory adherence for modern electronics.

Applications

• Status indication in consumer electronic devices
• Panel indicators for industrial control equipment
• Signal lights in automotive instrumentation

Procurement Notes

Verify the specific suffix designation against official Kingbright documentation to confirm exact optical and electrical characteristics, as variations exist within the AA4040 family. Ensure compatibility with standard SMT reflow processes and check moisture sensitivity levels prior to assembly. Confirm that the selected variant matches the required forward voltage and luminous intensity specifications for the target application circuit design.

Selection Notes

Select this component when a green indicator with moderate brightness is required in space-constrained designs. The 2-SMD form factor supports automated placement, while the 90-degree viewing angle suits applications requiring direct frontal visibility. Consider the 3.3 V forward voltage drop for appropriate current-limiting resistor calculation in low-voltage systems.

Part Context

This part belongs to the AA4040 series of single-color LEDs from Kingbright, which are engineered for high reliability in dense PCB layouts. The series typically includes various colors and lens configurations, all sharing a common PLCC-2 compatible footprint. These components are widely used in general-purpose electronics where standard-sized surface-mount indicators are preferred over through-hole alternatives.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other manufacturers offering equivalent 4x4mm green SMD LEDs only if electrical parameters match precisely.
