XL-3020UYC-FJ SMD LED — Technical Specifications & Design Guide

📌 Product Overview

The XL-3020UYC-FJ from XINGLIGHT is a high-performance 3.0 x 2.0 mm surface-mount LED designed for compact illumination and backlighting solutions. 🌟 It features a transparent water-clear colloid that produces a pure Yellow (585-595nm) light, making it ideal for applications requiring high visibility and color purity.

Beyond the optical performance, this component is engineered for modern automated assembly lines. It is fully compatible with SMT processes and infrared reflow soldering, provided the specific thermal profiles are respected. Designers should focus not just on the luminous intensity, but on the Moisture Sensitivity Level (MSL 3) requirements to prevent pop-corning during soldering.

🚀 Typical Applications

Based on its 120-degree viewing angle and compact form factor, the XL-3020UYC-FJ is highly versatile for various lighting segments:

  • Indoor Illumination: 💡 Optimized for fluorescent tubes, light strips, and downlights where consistent color temperature is critical.
  • Commercial Signage: 📈 Provides high brightness for advertising words and light boxes, ensuring messages are legible and vibrant.
  • LCD Backlighting: ✨ Suitable for indicator lights and display backlights due to its compact 3.0x2.0mm footprint.
  • Decorative Lighting: 🎨 Flexible light strips benefit from the wide 120° beam angle for smooth, even light mixing.

📊 Key Technical Specifications

The electrical and optical characteristics are measured under standard test conditions (Ta=25°C, IF=20mA).

Dominant Wavelengthλd585-595nm
Forward VoltageVF1.8-2.4V
Viewing Angle2Ø1/2-120-deg
Peak Wavelengthλp-590-nm

⚠️ Design Note: The component is sorted by brightness (Code D8-E1), voltage (N12-7 to N12-9), and wavelength (HY03-HY06). Ensure you specify the bin code during procurement to maintain color consistency in your final product.

🔒 Absolute Maximum Ratings & Process Limits

Exceeding these parameters may result in permanent device failure. These limits are critical for designing your drive circuitry and thermal management.

ParameterSymbolValueUnit
Max Power DissipationPD50mW
Max Continuous Forward CurrentIF20mA
Peak Forward CurrentIFP80mA
Max Reverse VoltageVR5V
ESD AbilityESD2000V
Storage TemperatureTstr-40 ~ +85°C

🛡️ Safety Margin: The peak forward current (80mA) is strictly for pulses ≤0.1ms with a duty cycle ≤1/10. Do not attempt to drive this continuously at 80mA.

📦 Package, Dimensions & Assembly Notes

  • Package Type: 3020 Surface Mount Device (SMD)
  • Dimensions (LxWxH): 3.0 mm × 2.0 mm × 1.3 mm
  • Moisture Sensitivity: Level 3 (MSL 3)
  • Packaging: EIA Standard Tape & Reel

⚠️ Assembly Critical Path: Because this is an MSL 3 component, it must be baked before reflow if the moisture barrier bag has been open for more than 168 hours. For soldering:

  • Lead-Free Process: Peak temp 255°C (Max 260°C), time above 217°C: 60-120s.
  • With-Lead Process: Peak temp 235°C, time above 183°C: 60-150s.
  • Max soldering time at 260°C is ≤6 seconds.

🛒 Sourcing & Supply Considerations

  • Bin Consistency: Always specify the Brightness (D8-E1) and Wavelength (HY03-HY06) codes to avoid batch-to-batch color variation.
  • Moisture Handling: Verify that your supplier ships in vacuum-sealed bags with desiccant; dry packing is essential for MSL 3 components.
  • Sample Evaluation: Request samples from the specific production batch if your application has tight color temperature requirements.
  • Authenticity: Source through authorized channels to ensure ROHS compliance and genuine XINGLIGHT quality.

❓ FAQ

Q: What does the "MSL 3" rating mean for my assembly line? A: MSL 3 means the LED is sensitive to moisture. If the floor life exceeds 168 hours after opening the bag, you must bake the components at 125°C for 24 hours before reflow soldering to prevent internal cracking ("pop-corning").

Q: Can I drive this LED at 30mA to get more brightness? A: No. The Absolute Maximum Continuous Forward Current is 20mA. While it can withstand 80mA pulses, driving it continuously above 20mA will rapidly degrade the junction and shorten the lifespan significantly.

Q: What is the difference between Dominant and Peak wavelength? A: The Peak Wavelength (590nm) is the physical intensity maximum, while the Dominant Wavelength (585-595nm) represents the color perceived by the human eye. For design matching, focus on the Dominant Wavelength.

Q: Is this LED suitable for outdoor flexible light strips? A: While suitable for flexible strips, the -40°C to +85°C operating range suggests it is best for indoor or protected commercial fixtures. If used outdoors, ensure the strip has an IP67+ protective coating, as the LED itself is not waterproof.

Q: How do I interpret the Voltage Grading codes (N12-7, N12-8, N12-9)? A: These codes indicate the forward voltage range (VF) at 20mA:

  • N12-7: 1.8V - 2.0V
  • N12-8: 2.0V - 2.2V
  • N12-9: 2.2V - 2.4V Selecting a specific bin helps in designing constant current drivers with tighter voltage regulation windows.
