📌 Product Overview
The XINGLIGHT XL-3528UOC is a high-intensity Orange SMD LED designed for 3528 footprint compatibility. It features a transparent water-clear colloid optimized for luminous intensity, peaking at 400 mcd.
👇 While the component fits standard SMT processes, successful integration requires careful attention to its Moisture Sensitivity Level (MSL 3) and forward voltage variance. Designers must balance the 120° viewing angle against thermal density to ensure stable luminance in commercial lighting modules.
💡 Typical Applications
Based on its 600–608 nm dominant wavelength and optical characteristics, the XL-3528UOC is suited for:
- Commercial & Retail Lighting: Shop counter and jewelry display cabinet illumination.
- Signage & Advertising: Luminescent characters and advertising module backlights.
- Functional Auxiliary: Indoor indication and mood lighting strips.

📦 Package, Dimensions & Assembly Notes
The component utilizes a standard 3.5 x 2.8 x 1.9 mm EIA package compatible with automated SMT placement.
✨ Critical Assembly Guidelines:
- Moisture Sensitivity: Classified as MSL 3. Components must be baked (pre-conditioning) if floor life exceeds 168 hours before reflow to prevent "popcorning" or internal cracking.
- Soldering Profile: Suitable for infrared reflow.
- Lead-Free: Max temp 255°C (Time above 217°C: 60-120s).
- Lead Process: Max temp 235°C (Time above 183°C: 60-150s).
- Soldering Limits: Manual repair should not exceed 260°C for >6 seconds.
🚀 Sourcing & Supply Considerations
To ensure supply chain reliability for the XL-3528UOC:
- Authenticity Verification: Always procure through authorized XINGLIGHT channels to avoid counterfeit components with unreliable thermal or binning performance.
- Bin Consistency: Verify brightness (D9/E1) and voltage (N12-7/8/9) bin codes to ensure uniformity in large-scale installations.
- Sample Evaluation: Request pre-production samples to validate the specific wavelength bin (HO01-HO03) under your actual operating conditions.
❓ FAQ
Q: What does MSL 3 mean for my assembly line? A: MSL 3 (Moisture Sensitivity Level 3) means the LED absorbs moisture from the air. You must bake the components before reflow soldering if they have been exposed to the factory floor for more than 168 hours (7 days) to prevent internal damage during heating.
Q: Can I drive this LED at 30mA for higher brightness? A: No. The Absolute Maximum Continuous Forward Current is 20mA. Exceeding this will rapidly degrade the LED junction and shorten lifespan, even if the thermal pad is heatsinked.
Q: Why is the Forward Voltage range so wide (1.8V - 2.4V)? A: This variance is typical for LED chemistry. If driving multiple LEDs in parallel, you may need individual resistors or current regulation to ensure uniform brightness, as lower Vf LEDs will draw more current.
Q: What is the difference between Dominant and Peak Wavelength? A: Peak Wavelength (605 nm) is the physical maximum emission. Dominant Wavelength (600-608 nm) is the color perceived by the human eye. This unit ensures the perceived color remains stable orange.
Q: Is this component RoHS compliant? A: Yes, the datasheet explicitly states compliance with the ROHS Directive, utilizing environmentally friendly materials and processes.
