C503B-AAS-CZ0C0341

Overview

The C503B-AAS-CZ0C0341 is a blue light-emitting diode from the Cree LED series, housed in a 5 mm (T-1 3/4) through-hole package with two pins. It features a clear, colorless lens and emits at a dominant wavelength of 470 nm. The component operates with a forward voltage of 4 V and a maximum forward current of 30 mA. It delivers a luminous intensity of 23500 mcd with a viewing angle of 15 degrees. The device has a maximum power dissipation of 120 mW and complies with RoHS standards.

Feature Summary

• High-brightness output suitable for outdoor readability
• Advanced optical-grade epoxy for high temperature and moisture resistance
• UV inhibitors minimize effects of long-term sunlight exposure

Applications

• Electronic Signs & Signals (ESS)
• Motorway Signs
• Variable-Message Sign (VMS)

Procurement Notes

Verify the specific suffix CZ0C0341 against official Cree documentation to confirm availability and exact electrical parameters, as distributor listings may vary. Check for end-of-life status or alternative packages if current stock is limited. Ensure the ordering suffix matches the required lens and binning specifications for your design.

Selection Notes

Select this component for applications requiring high-intensity blue illumination with a narrow 15-degree beam angle. The 5 mm T-1 3/4 package offers robust mechanical stability for through-hole mounting. Consider the 4 V forward voltage drop when designing drive circuits. Verify thermal management requirements given the 120 mW power dissipation limit.

Part Context

This part belongs to the C503B family of 5 mm round LEDs designed for transport signage. The AAS suffix typically denotes amber variants in the datasheet, but the specific model provided is identified as blue. This family utilizes advanced encapsulation resin for durability in harsh outdoor environments, ensuring stable light output over the LED's lifespan.
