📌 Product Overview
The XL-3014SURC-02 from XINGLIGHT is a high-intensity 3.0x1.4mm SMD LED designed for automated surface-mount assembly. 🔥 This component features a transparent water-clear colloid that delivers a dominant red wavelength (615-630nm), making it ideal for compact lighting solutions requiring strong luminous intensity.
💡 While the typical luminous intensity ranges up to 900 mcd, the real design focus lies in managing its thermal dissipation. With a maximum power rating of 200 mW, engineers must ensure adequate PCB thermal relief to maintain longevity and color stability in dense arrays.
🚀 Typical Applications
Thanks to its compact 3014 footprint and high brightness, this LED is versatile for various commercial and consumer electronics.
- Indoor Illumination: 💡 Ideal for rigid light strips and tube lighting where consistent color rendering is crucial.
- LCD Backlighting: Provides efficient red light sources for display panels and indicator arrays.
- Automotive Interiors: Suitable for auxiliary dashboard lighting and footwell illumination, complying with strict automotive temperature ranges.
- Commercial Signage: 📈 Effective for advertising boards and light boxes requiring high-intensity red output to cut through ambient light.

📦 Package, Dimensions & Assembly Notes
This device utilizes a standard 3014 surface-mount package with a moisture sensitivity level (MSL) of 3.
- Dimensions: The outline measures $3.0 \times 1.4 \times 0.8\text{mm}$ (L x W x H).
- Soldering: Compatible with infrared reflow soldering processes.
- Lead-Free Process: Peak temp $255^\circ\text{C}$ ($+0/-5^\circ\text{C}$) for 5-10 seconds.
- Lead Process: Peak temp $235^\circ\text{C}$ ($\pm 5^\circ\text{C}$) for 10-15 seconds.
- Placement: Designed for SMT automatic production lines using standard EIA packaging tape.
👇 Assembly Tip: Since MSL is 3, ensure the components are baked according to J-STD-033 guidelines if the floor life has been exceeded prior to reflow to prevent "popcorning" or delamination.
🛒 Sourcing & Supply Considerations
When integrating the XL-3014SURC-02 into production, consider the following supply chain factors:
- Bin Sorting: Verify the specific Brightness (E5-E8), Voltage (N12-7 to N12-9), and Wavelength (HR01-HR03) bins required for your optical consistency.
- Authenticity: Source exclusively through XINGLIGHT authorized channels to avoid counterfeits that may not meet the ROHS compliance or reliability standards.
- Sample Availability: Request engineering samples for prototyping to validate the thermal design in your specific enclosure before mass production.
❓ Frequently Asked Questions (FAQ)
Q: What is the MSL level of the XL-3014SURC-02, and why does it matter?
A: The MSL is Level 3. This means the component can withstand floor life of up to 168 hours (one week) in a factory environment (<30°C/60% RH) after opening the vacuum-sealed bag before it must be reflowed to avoid moisture-induced damage.
Q: Can this LED be used in outdoor lighting fixtures?
A: While it has an operating range of -40°C to +85°C, the package is not rated for direct UV exposure or water immersion. It is suitable for indoor or automotive interior use, or outdoor fixtures inside sealed, IP-rated light engines.
Q: What is the difference between Dominant and Peak Wavelength?
A: The Peak Wavelength ($\lambda_p$) is the physical maximum emission (625nm), while the Dominant Wavelength ($\lambda_d$: 615-630nm) represents the color perceived by the human eye. Designers should use $\lambda_d$ for color matching.
Q: How should I handle the component regarding ESD?
A: The device has a 2000V ESD rating. While this offers some protection, it is relatively low. Always use grounded workstations, conductive mats, and personnel grounding when handling these bare LEDs.
Q: What is the recommended reflow profile for this LED?
A: Use a standard profile for lead-free soldering. Ramp up at max $3^\circ\text{C}/\text{s}$, soak above $217^\circ\text{C}$ for 60-120 seconds, and peak at $255^\circ\text{C}$ ($+0/-5$) for 5-10 seconds.
Q: How do I interpret the Brightness Grading codes?
A: The codes E5 through E8 represent intensity bins at 60mA.
- E5: 550-600 mcd
- E8: 800-900 mcd
Select the appropriate bin based on your brightness requirements and budget.
