📌 Product Overview
The XL-2835SURC-02 is a high-intensity red SMD LED manufactured by XINGLIGHT. 💡 Housed in a compact 2.8x3.5x0.8mm package with a water-clear colloid, it is designed for automated SMT production and infrared reflow soldering processes.
👇 Target applications primarily include indoor and commercial lighting, such as flexible light strips, downlights, and LCD backlights. While the component offers robust luminous intensity, successful integration depends on strictly observing its forward voltage and thermal dissipation limits to ensure long-term reliability.
💡 Typical Applications
Based on the XL-2835SURC-02's optical characteristics and 120-degree viewing angle, this model is best suited for applications requiring wide-angle illumination and efficient brightness.
- Indoor Lighting: Fluorescent tubes, residential light strips, and downlight fixtures.
- Commercial Signage: Illuminated advertising words and light boxes where color consistency is vital.
- Backlighting: LCD backlight sources for displays and indicator panels.
- Decorative Lighting: Flexible light strips that require low-profile components.

🚀 Sourcing & Supply Considerations
To ensure supply chain stability and product authenticity, consider the following when procuring the XL-2835SURC-02:
- Bin Selection: Verify specific brightness (E5-E8) and voltage (N12-7/8/9) codes to match your driver design.
- Authenticity: Source exclusively through XINGLIGHT authorized channels or verified distributors to avoid counterfeit components.
- Sampling: Request samples for prototyping to validate color binning and thermal performance in your specific housing.
- Lead Time: Check stock availability for high-volume orders to prevent production line stoppages.
❓ FAQ
Q: What is the maximum current I can drive the XL-2835SURC-02 with continuously? A: The maximum continuous forward current (IF) is 60mA. While it can handle pulses up to 150mA, exceeding 60mA DC will likely cause thermal failure or significantly reduce lifespan.
Q: Is this LED compatible with lead-free soldering processes? A: Yes, it is designed for infrared reflow. For lead-free processes, the peak temperature should not exceed 255℃+0/-5℃ for 5-10 seconds, with a heating rate limited to 3℃/second.
Q: What does the viewing angle of 120 degrees imply for my design? A: The 120-degree viewing angle indicates a wide light dispersion. This makes the component ideal for area lighting and diffusers where uniform light mixing is required, rather than spot lighting.
Q: How should I handle the component regarding moisture? A: The XL-2835SURC-02 has a Moisture Sensitivity Level (MSL) of 3. If the packaging has been opened, the components should be baked according to J-STD-033 standards before reflow to prevent moisture-induced damage.
Q: What is the typical forward voltage range I should expect? A: At 60mA, the forward voltage ranges from 1.8V to 2.4V. Ensure your LED driver can supply sufficient voltage to cover the maximum VF in a series string configuration.
