19-22/G6R6C-A31/2T

LED Indication - Discrete Overview

The 19-22/G6R6C-A31/2T is a dual-chip surface-mount LED manufactured by Everlight Electronics Co Ltd. It features separate red and yellow-green emitters housed in a 4-SMD, no-lead package with dimensions of 1.90mm length, 1.60mm width, and a maximum height of 0.90mm. The device utilizes AlGaInP material technology. The red element emits at a peak wavelength of 632nm with a typical forward voltage of 2V and a luminous intensity of 78.5mcd at 20mA. The yellow-green element operates at a peak wavelength of 575nm, also with a 2V forward voltage and an intensity of 58.5mcd at 20mA. The lens is clear and rectangular with a flat top, providing a viewing angle of 130 degrees.

LED Indication - Discrete Feature Summary

• Dual-color configuration combining red and yellow-green elements within a single compact SMD footprint.
• Compatible with standard infrared and vapor phase reflow soldering processes for automated assembly.
• Lead-free construction compliant with environmental standards.
• High brightness output suitable for indicator applications in space-constrained designs.

LED Indication - Discrete Applications

• Status indicators in telecommunications equipment such as telephones and fax machines.
• Dashboard and switch backlighting in automotive systems.
• LCD backlighting and symbol illumination for general electronic devices.

LED Indication - Discrete Procurement Notes

Verify the specific suffix A31 against the manufacturer's latest datasheet to confirm current binning and intensity grades, as manufacturing updates may alter performance characteristics. Ensure compatibility with the intended PCB pad layout for the 4-SMD no-lead package. Confirm that the clear lens type meets the optical requirements for the target application environment. Cross-reference the part number with official distributor catalogs to ensure availability and correct ordering specifications.

LED Indication - Discrete Selection Notes

Select this component when a dual-color indication is required in a minimal board area. The 1.90mm x 1.60mm size allows for high packing density compared to lead-frame components. Consider the 130-degree viewing angle for visibility requirements. The separate cathode/anode structure for each color allows independent control of the red and yellow-green states. Verify thermal management capabilities if operating near the maximum rated conditions.
