QBLP679E-RGB

LED Indication - Discrete Overview

The QBLP679E-RGB is a tri-color surface-mount LED from the QBLP679 series by QT Brightek. It features a PLCC-6 package with J-leads and a round, diffused lens. The component integrates red, true green, and blue emitters within a single unit. Electrical characteristics include a forward voltage of 2V for red, 3.3V for green, and 3.2V for blue at a test current of 20mA. Luminous intensity values are specified as 840mcd for red, with corresponding intensities for green and blue channels.

LED Indication - Discrete Feature Summary

• Integrates red, true green, and blue light sources in a compact PLCC-6 form factor
• Utilizes InGaN technology for green and blue channels alongside AlInGaP for red
• Features a diffused lens design to provide uniform light distribution
• Supports direct drive applications with a wide 120-degree viewing angle

LED Indication - Discrete Applications

• Status indication in electronic devices requiring multi-color signaling
• Backlighting solutions for control panels and user interfaces
• Decorative lighting systems utilizing RGB color mixing capabilities
• Indicator lights for consumer electronics and appliances

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version when sourcing, as luminous intensity specifications may vary slightly between revisions. Confirm that the PLCC-6 package dimensions align with the target PCB footprint. Ensure compatibility with standard reflow soldering profiles for J-lead components. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate the forward voltage requirements against the driving circuit design.

LED Indication - Discrete Selection Notes

Select this component when a compact, multi-color indicator is required without separate discrete LEDs. The PLCC-6 package offers a balance between size and thermal performance. Consider the diffused lens type for applications requiring soft, non-glaring illumination. The common anode configuration simplifies circuit design for standard switching applications. Evaluate the 120-degree viewing angle to ensure adequate visibility from the intended observation positions.

LED Indication - Discrete Part Context

This part belongs to the QBLP679 series, which includes various single-color and tri-color options. The series utilizes a standardized PLCC-6 footprint, allowing for flexible design choices within the same mechanical envelope. Other variants in the family include pure green or warm white configurations, sharing similar electrical and mechanical characteristics while differing in optical output.

LED Indication - Discrete Replacement Considerations

Direct substitutes within the same series include other QBLP679E variants with different lens colors or emission wavelengths. Cross-reference mechanical dimensions with alternative PLCC-6 RGB LEDs from other manufacturers to ensure pinout compatibility. Verify that replacement parts maintain the same forward voltage characteristics to avoid circuit redesign.
