📌 Product Overview
The XL-2214SURC is a high-intensity Red SMD LED designed by XINGLIGHT, featuring a compact 2.2x1.4x1.35mm outline with a transparent water-clear colloid. It utilizes advanced AlGaInP technology to deliver luminous intensity up to 1200 mcd.
💡 This component is specifically engineered for automotive interior lighting and commercial signage. Designers must focus on the Moisture Sensitivity Level (MSL 3) requirement to prevent pop-corning during reflow soldering. While the electrical drive is standard, the real design challenge lies in managing the 120-degree viewing angle and heat dissipation in dense flexible strip arrays.
🚀 Typical Applications
Based on the 625nm dominant wavelength and robust 2.2mm footprint, this model is optimized for the following scenarios:
- Automotive Interiors: Dashboard indicators and mood lighting where stable color (615-630nm) is critical.
- Commercial Signage: Lightboxes and advertising characters requiring high-intensity output (E8-F1 bins) for visibility.
- LCD Backlighting: Side-view or direct backlight solutions for small displays.
- Flexible Light Strips: Decorative lighting where the low 1.35mm profile facilitates low-profile designs.

📦 Package, Dimensions & Assembly Notes
The XL-2214SURC comes in a lead-free, EIA-compliant package. Key physical considerations for your PCB layout and stencil design include:
- Dimensions: The body size is strictly 2.2mm (L) x 1.4mm (W) x 1.35mm (H). Tolerance is generally $\pm 0.25mm$ unless noted.
- Soldering Guidelines:
- Hand Soldering: Use an iron $<30W$ at $<300^\circ C$ for max 3 seconds per terminal.
- Reflow: Recommended for SMT. Reflow should not exceed 2 times.
- MSL 3:Baking is required if the moisture barrier bag has been open for more than 168 hours (floor life) to prevent internal cracking during reflow.
- Handling: Avoid mechanical stress on the silicone colloid during the pick-and-place process.
📈 Sourcing & Supply Considerations
When integrating the XL-2214SURC into mass production, verify the following supply chain factors to ensure consistency:
- Bin Selection: Confirm brightness (E8-F1) and voltage (N11-4/5) bins with your distributor to match driver circuits.
- Authenticity: Source from authorized channels to guarantee ROHS compliance and MSL 3 integrity.
- Packaging: Available in EIA standard tape and reel for automated SMT assembly.
❓ FAQ
Q: What is the forward voltage drop for this LED? A: The typical forward voltage ($V_F$) is around 2.0V, but it can range from 1.9V to 2.3V at a standard forward current of 20mA. Your current limiting resistor calculation should account for the maximum 2.3V.
Q: Can this LED be used in outdoor environments? A: The datasheet specifies storage and operating temperatures from -40°C to +85°C, which covers most outdoor climates. However, the package is not rated for prolonged UV exposure or direct water ingress without an IP-rated enclosure.
Q: What does Moisture Sensitivity Level (MSL) 3 mean for my assembly line? A: MSL 3 means the components are sensitive to moisture. After opening the vacuum-sealed bag, you have 168 hours (1 week) to mount the components before they must be baked to drive out moisture. Skipping this step can cause "pop-corning" (internal cracking) during reflow.
Q: What is the difference between Dominant Wavelength and Peak Wavelength? A: The Peak Wavelength ($\lambda_p$) is the physical maximum emission at 625nm. The Dominant Wavelength ($\lambda_d$) represents the color perceived by the human eye, ranging from 615nm to 630nm.
Q: Is this component compatible with lead-free soldering processes? A: Yes, the XL-2214SURC is compliant with ROHS directives and suitable for lead-free soldering. The datasheet provides a specific temperature profile for lead-free reflow to ensure joint integrity without damaging the LED.
Q: How should I handle these components to prevent ESD damage? A: The LED has an ESD tolerance of 2000V. While this is moderate, standard precautions are necessary: use grounded wrist straps, anti-static mats, and ionizers in the assembly area to prevent latent damage.
