📌 Product Overview
The XL-3433SURC-02 is a high-reliability Red SMD LED designed by XINGLIGHT for surface-mount technology (SMT) assembly. 🚀 Housed in a compact 3.4x3.3x1.9mm package with a colorless transparent lens, it delivers a dominant wavelength of 625nm (615-630nm), making it ideal for high-intensity automotive and commercial illumination. 💡 While the component is rated for a continuous forward current of 60mA, successful integration requires careful attention to its Moisture Sensitivity Level (MSL 3) and infrared reflow compatibility to ensure long-term stability in harsh environments.
🔦 Typical Applications
Based on its robust 3433 package size and luminous intensity range (13-27 LM), this component is optimized for applications requiring durability and wide viewing angles.
- Automotive Lighting: Tail lights, stop lights, and interior cabin illumination.
- Commercial Signage: Advertising lightboxes and channel letters.
- Backlighting: LCD indicators and switch illumination.
- Decorative Lighting: Flexible light strips and accent lighting.

❓ FAQ
Q: What is the Moisture Sensitivity Level (MSL) of this LED?
A: The XL-3433SURC-02 is classified as MSL 3. This means it has a floor life of 168 hours after opening the moisture barrier bag. It must be reflowed within this window or baked according to J-STD-033 standards to prevent popcorning damage during soldering.
Q: Can this LED be used for automotive exterior lighting?
A: Yes, the datasheet explicitly lists "Car tail lights" and "brushing lights" (likely wash/reverse lights) as target applications. However, designers must verify that the specific intensity bin (13-27 LM) meets local regulatory luminance requirements for their specific housing design.
Q: What is the maximum current I can drive through this component?
A: The Absolute Maximum Continuous Forward Current is 60mA. While pulses up to 120mA are allowed (≤0.1ms pulse width), driving it continuously above 60mA will likely degrade the junction and shorten lifespan.
Q: What are the soldering profile limits for lead-free assembly?
A: For lead-free processes, the peak temperature should not exceed 255°C. The ramp rate should be ≤3°C/s, and the time above 217°C should be controlled between 60 to 120 seconds to ensure proper wetting without damaging the package.
Q: How is the brightness sorted for this model?
A: Brightness is sorted into specific codes based on Luminous Intensity (Φ) at 60mA. Codes range from H8 (13-17 LM) to J2 (23-27 LM). Selecting the correct bin is crucial for maintaining uniform light output in large arrays.
