QLSP27RD

Overview

The QLSP27RD is a red discrete LED indicator manufactured by Quelighting Corp. It utilizes a 3528 PLCC-2 package with a high output reflector design. The device emits light at a wavelength of 625nm and operates with a forward voltage of 2V. Key electrical characteristics include a typical drive current of 50mA and a viewing angle of 30 degrees. The component is designed for status indication applications requiring high brightness output.

Feature Summary

• High brightness output capability at standard drive currents
• Integrated high output reflector design for improved luminous efficiency
• Standard 3528 PLCC-2 surface mount package configuration

Applications

• Status indication in electronic devices
• Power supply indicators
• Control panel signaling

Procurement Notes

Verify the specific datasheet version from Quelighting Corp to confirm exact binning and optical parameters. Ensure compatibility with PCB footprint dimensions for the 3528 PLCC-2 package. Cross-reference the forward voltage requirements with the target circuit design to prevent overdriving. Confirm that the 625nm red emission aligns with visibility requirements for the intended application environment.

Selection Notes

Select this component when a compact, high-brightness red indicator is required for surface-mount assembly. The 30-degree viewing angle suits applications where direct line-of-sight is available. Consider the 2V forward voltage drop when designing series resistor networks or constant current drivers. The PLCC-2 form factor allows for automated placement on standard SMT lines.

Part Context

This part belongs to the 3528 LED family from Quelighting Corp, which focuses on advanced optoelectronic devices. The QLSP27RD represents a standard red indicator variant within their discrete LED portfolio. It shares the physical dimensions and mounting style with other colors in the same series, differing primarily in semiconductor material and resulting emission wavelength.

Replacement Considerations

Direct substitutes must match the 3528 PLCC-2 package, 625nm red emission, and similar forward voltage characteristics. Verify that alternative components offer comparable luminous intensity at 50mA. Ensure thermal management requirements are consistent with the original design specifications.
