APDA1806SECK

Overview

The APDA1806SECK is a high-brightness, single-color LED component manufactured by Kingbright. It utilizes an amber-colored gallium aluminum phosphide (AlGaP) die housed within a surface-mount package designed for PCB mounting. The device features a clear epoxy lens to maximize light output and visibility. Key electrical parameters include a forward voltage typically ranging from 2.0V to 2.4V at standard test conditions, with a peak forward current rating of 50mA. The component operates reliably within a junction temperature range of -40°C to +85°C and offers storage capabilities between -40°C and +100°C.

Feature Summary

• High luminous intensity for superior visibility in ambient lighting conditions
• Surface-mount design facilitates automated assembly processes
• Clear encapsulant enhances light transmission efficiency
• Robust construction suitable for industrial and commercial environments

Applications

• Status indicators on electronic control panels
• Backlighting for push-button switches
• Visual alerts in automotive instrumentation clusters
• Indicator lights for household appliances

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure compatibility with required wavelength and binning specifications. Confirm that the requested part number matches the exact package dimensions and pin configuration needed for your PCB footprint. Cross-reference the RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure that static-sensitive handling procedures are followed during storage and assembly to prevent electrostatic discharge damage to the semiconductor junction.

Selection Notes

Select this component when a compact, high-efficiency amber indicator is required for space-constrained designs. Consider the forward voltage drop relative to your driving circuit's supply voltage to ensure proper biasing without excessive current limiting resistors. Evaluate the viewing angle requirements of your application to confirm adequate visibility from the intended user perspective. Assess the thermal management capabilities of your system to maintain junction temperatures within safe operating limits during continuous operation.

Part Context

This model belongs to Kingbright's SMD LED series, which focuses on providing reliable optical solutions for modern electronics. The APDA1806SECK represents a specific variant optimized for amber emission, distinguishing it from red or green counterparts in the same family. It shares common mechanical footprints with other components in the series but differs in spectral output and electrical characteristics due to the distinct semiconductor material used.

Replacement Considerations

Direct replacements must match the physical outline drawing and terminal arrangement to fit existing PCB layouts. Verify that substitute parts offer comparable luminous intensity and forward voltage to maintain consistent performance. Check for identical packaging materials and lead finish specifications if solderability or corrosion resistance is critical. Consult official substitution lists provided by Kingbright for validated alternative part numbers.
