C4SMM-BJY-CN3Q2352

Overview

The C4SMM-BJY-CN3Q2352 is a single-color blue LED from the Screen Master series by Cree LED. It features a 4 mm oval lens package with two radial leads for through-hole mounting. The component emits light at a dominant wavelength of 468 nm to 475 nm. Electrical characteristics include a forward voltage of approximately 3 V to 4 V and a test current of 10 mA. Luminous intensity ratings vary between 240 mcd and 355 mcd depending on specific binning, with some sources citing up to 2.1 cd. It operates reliably at temperatures up to +105°C.

Feature Summary

• High-brightness blue emission suitable for bright sunlight visibility
• Oval domed lens design for directional light distribution
• Robust construction supporting high-temperature operation up to +105°C

Applications

• Outdoor indicator applications requiring high visibility
• Low-power consumption outdoor lighting systems
• Commercial downlighting components

Procurement Notes

Verify the exact luminous intensity bin and dominant wavelength against the manufacturer's latest datasheet, as distributor listings show variations in reported brightness (mcd) and wavelength (nm). Confirm that the 4 mm oval package dimensions match your PCB footprint requirements. Ensure the supplier provides RoHS compliance documentation consistent with the component's environmental specifications.

Selection Notes

Select this component when high-intensity blue indication is required for outdoor or high-ambient-light environments. The 4 mm oval form factor offers a distinct visual profile compared to standard round LEDs. Consider the operating temperature range up to +105°C if the application involves heat-generating surroundings or enclosed fixtures without active cooling.

Part Context

This part belongs to the Screen Master series, designed specifically for high-visibility applications. It utilizes Cree LED's proprietary phosphor technology to achieve stable color performance. The component serves as a discrete indicator element within larger lighting assemblies or control panels where reliable blue signaling is critical.

Replacement Considerations

Direct substitutes must match the 4 mm oval package, 468–475 nm wavelength, and similar forward voltage characteristics. Verify mechanical lead spacing and lens shape compatibility before substitution.
