AA4040SURSK

Overview

The Kingbright AA4040SURSK is a single-color red surface-mount LED housed in a PLCC-2 package. It emits light at a peak wavelength of 630 nm with a water clear dome lens. The component operates with a forward current of 20 mA and a forward voltage of 1.95 V, rated for 75 mW power dissipation. It provides an optical intensity of 450 mcd and features a 120-degree viewing angle. Physical dimensions are 4 mm height, 4 mm width, and 3.6 mm length. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Water clear dome lens design for optimized light transmission
• RoHS compliant construction suitable for dense system designs
• Second-generation SMD LED offering improved material durability

Applications

• Panel indicator lighting
• Machine status signaling
• Consumer electronics display illumination

Procurement Notes

Verify the specific suffix against official Kingbright documentation to confirm exact optical and electrical characteristics. Ensure compatibility with standard PLCC-2 footprint layouts during procurement planning. Confirm moisture sensitivity level requirements for storage and handling procedures prior to assembly.

Selection Notes

Select this component when a compact red indicator with high brightness is required. The 120-degree viewing angle supports wide-area visibility applications. Verify that the 1.95 V forward voltage aligns with the target circuit drive capabilities. Consider the 4 mm height constraint for strict profile limitations.

Part Context

This part belongs to the Kingbright AA4040 series of second-generation surface-mount LEDs. The series emphasizes enhanced reliability and material durability for modern electronic assemblies. The PLCC-2 form factor allows for automated pick-and-place manufacturing processes.

Replacement Considerations

The KA-4040SURSK is listed as an alias for this part number. Cross-reference with other AA4040 series variants only if wavelength or intensity differences are acceptable.
