5991A30147F

Overview

The Dialight 5991A30147F is a surface-mount infrared LED emitter from the MicroLED series, housed in a compact 0402 (1005 metric) package. It emits at a dominant wavelength of 606 nm with a typical forward voltage of 2 V and a test current of 20 mA. The component features a rectangular lens with flat top geometry and offers a viewing angle of 118° to 160°. Designed for high reliability, it supports moisture sensitivity standards and operates within standard industrial temperature ranges, making it suitable for precision optical sensing applications.

Feature Summary

• Compact 0402 surface-mount footprint for dense PCB layouts
• Rectangular lens with flat top design for directional emission
• Wide viewing angle range supporting flexible alignment
• Optimized for low-power infrared data communication

Applications

• Infrared remote control transmitters
• Optical proximity sensors
• Short-range data communication links
• Consumer electronics IR interfaces

Procurement Notes

Verify RoHS compliance status through official manufacturer documentation prior to integration. Confirm moisture sensitivity level handling requirements during storage and reflow soldering processes. Ensure supply chain sources provide authentic components with traceable manufacturing batches to maintain quality standards.

Selection Notes

Select this component when space constraints require a 0402 form factor combined with specific 606 nm spectral output. Consider the wide viewing angle for non-critical alignment scenarios. Evaluate thermal management needs against the 2 V forward voltage drop at 20 mA test current conditions.

Part Context

Part of the Dialight MicroLED family, designed for high-volume consumer and industrial electronics. The 5991 series emphasizes miniaturization while maintaining consistent optical performance across production batches. This model represents a standard solution for embedded IR signaling tasks.

Replacement Considerations

Cross-reference with other 0402 IR LEDs offering similar 606 nm wavelengths and comparable forward voltage characteristics. Verify mechanical compatibility with existing footprints before substitution.
