5991A80147F

Overview

The Dialight 5991A80147F is a single-color green surface-mount LED from the MicroLED series, designed for discrete indication applications. It features a 0402 (1005 metric) package with a water-clear lens and a viewing angle of 100° to 150°. The component emits light at a dominant wavelength of 528 nm with a typical forward voltage of 2.8 V when tested at 5 mA. It operates within a temperature range of -40°C to +85°C and is moisture sensitive.

Feature Summary

• Compact 0402 surface-mount form factor suitable for high-density PCB layouts
• Green emission at 528 nm with wide viewing angles for enhanced visibility
• Water-clear lens design optimized for standard indicator applications

Applications

• Panel-mounted status indicators
• Board-level activity signaling
• Consumer electronics status lights

Procurement Notes

Verify RoHS compliance and moisture sensitivity level (MSL) ratings prior to assembly. Confirm that the 0402 package dimensions align with the target footprint. Ensure handling procedures account for humidity sensitivity during reflow soldering processes.

Selection Notes

Select this part for applications requiring a compact green indicator with broad viewing angles. Compare the 2.8 V forward voltage against available drive circuits. Consider the 100° to 150° viewing angle for line-of-sight requirements relative to larger angle alternatives.

Part Context

This component belongs to the Dialight MicroLED family, which specializes in small-footprint surface-mount LEDs. The 5991 series provides reliable optical performance for general-purpose indication tasks across various industrial and consumer sectors.

Replacement Considerations

Cross-reference other 0402 green LEDs from Dialight or competitors. Verify matching wavelength, forward voltage, and package dimensions before substitution.
