VLMKG3400-GS18

LED Indication - Discrete Overview

The VLMKG3400-GS18 is a dual-color surface-mount LED from Vishay, featuring green and red emitters in a 4-PLCC package. It operates with a typical forward voltage of 2.2V for the green channel and 2.1V for the red channel at a test current of 20mA. The device emits light at peak wavelengths of 565nm (green) and 630nm (red). With a viewing angle of 120 degrees and dimensions of 3.00mm x 2.80mm x 1.85mm, it provides clear lens visibility for status indication applications.

LED Indication - Discrete Feature Summary

• Dual-color configuration combining green and red LEDs within a single compact package
• Standard J-leaded 4-SMD surface mount design for automated assembly
• Clear non-diffused lens with round flat style for direct visibility

LED Indication - Discrete Applications

• Status indication on electronic circuit boards
• Power supply front panel indicators
• Consumer appliance control panels

LED Indication - Discrete Procurement Notes

Verify the GS18 suffix confirms the specific reel packaging format required for your SMT line. Ensure compatibility with standard reflow profiles as defined in the Vishay datasheet. Confirm that the 4-PLCC footprint matches your PCB layout exactly to avoid placement errors during manufacturing.

LED Indication - Discrete Selection Notes

Select this component when space constraints require two distinct indicator colors in a minimal footprint. The 120-degree viewing angle offers broad visibility compared to narrower beam devices. Consider the separate drive requirements for the independent anodes/cathodes inherent to the dual-emitter structure.

LED Indication - Discrete Part Context

This part belongs to the VLM.3 series of high-brightness LEDs from Vishay Semiconductor Opto Division. The series is characterized by small form factors suitable for dense PCB layouts. The 4-PLCC package allows for efficient board utilization while maintaining reliable thermal performance for continuous operation.

LED Indication - Discrete Replacement Considerations

Direct substitutes include the VLMKG3400-GS08, which shares identical electrical and optical characteristics but differs in tape and reel packaging specifications.
