📌 Product Overview
The XL-3020UWC-A from XINGLIGHT is a 3.0mm x 2.0mm surface-mount device (SMD) LED designed for high-density lighting arrays. It features a white light source with a yellow colloid, optimized for general illumination and backlighting. 💡 While the component appears standard, successful integration requires careful attention to its thermal dissipation limits and forward voltage variance to ensure consistent luminosity.
This component is specifically engineered for SMT automatic production and infrared reflow soldering processes. Designers should focus on the 120-degree viewing angle and Color Rendering Index trade-offs when selecting this unit for commercial lighting displays. 🚀 Ensuring the drive current stays within the 20mA continuous rating is critical for maintaining the specified luminous intensity of 5 to 10 lumens.
🎯 Typical Applications
Based on the 3020 package size and 6000-7000K color temperature, the XL-3020UWC-A is suited for environments requiring cool white light and compact form factors:
- Indoor Lighting: Ideal for fluorescent tubes, light strips, and downlights where space is constrained.
- Commercial Signage: Designed for advertising words and light boxes requiring high reliability and consistent color temperature.
- LCD Backlighting: Provides uniform illumination for display panels.
- Decorative Lighting: Suitable for flexible light strips used in ambient or accent lighting.
📊 Key Technical Specifications
💡 The following table outlines the optical and electrical characteristics under standard test conditions (Ta=25°C).
| Parameter | Symbol | Min. | Typ. | Max. | Unit | Test Conditions |
|---|---|---|---|---|---|---|
| Luminous Intensity | Φ | 5 | - | 10 | LM | IF = 20mA |
| Color Temperature | TC | 6000 | - | 7000 | K | IF = 20mA |
| Forward Voltage | Vf | 2.8 | - | 3.4 | V | IF = 20mA |
| Viewing Angle | 2θ1/2 | - | 120 | - | Deg | IF = 20mA |

⚠️ Thermal Warning: The maximum soldering temperature is 260°C for ≤ 6 seconds. Prolonged exposure beyond this time will degrade the internal phosphor layer and epoxy.
📦 Package, Dimensions & Assembly Notes
The XL-3020UWC-A utilizes a standard 3020 footprint (3.0mm x 2.0mm x 1.3mm). The package features a white appearance with a yellow colloid optimized for light extraction.
Soldering Guidelines:
- Process: Suitable for infrared reflow soldering.
- Moisture Sensitivity:MSL Level 3. Components must be baked if exposed to ambient moisture for extended periods before reflow to prevent "popcorning."
- Packaging: EIA standard compliant, ensuring compatibility with modern pick-and-place machines.
🛒 Sourcing & Supply Considerations
- Bin Selection: Verify specific bin codes for Brightness (H4-H6), Voltage (N13-3 to N13-5), and Color Temperature (UW8-10/UW11-10) to match your design.
- Authenticity: Source exclusively through authorized XINGLIGHT channels to avoid counterfeits that fail ROHS compliance.
- Samples: Request samples for prototype testing to validate thermal management in your specific PCB layout.
- Lead Time: Confirm stock availability for high-volume commercial lighting projects to avoid production delays.
❓ FAQ
Q: What is the MSL level of the XL-3020UWC-A and why does it matter? A: The MSL is Level 3. This means the components are sensitive to moisture. If the floor life is exceeded after opening the vacuum seal, they must be baked at 125°C according to J-STD-033B to prevent internal damage during reflow soldering.
Q: Can this LED be used in outdoor lighting fixtures? A: The datasheet specifies "Indoor lighting" and "Commercial lighting display." While the operating temperature range is -40°C to +85°C, the IP rating of the final fixture must be considered. The LED itself is not inherently waterproof without a proper enclosure.
Q: What is the maximum current I can drive this LED with? A: The Max Continuous Forward Current is 20 mA. While it can withstand pulses up to 80 mA, exceeding 20 mA continuously will likely cause thermal runaway and permanent lumen degradation.
Q: What reflow profile should be used for this component? A: It is suitable for both Lead (Max 235°C) and Lead-free (Max 255°C) processes. For lead-free, the ramp-up rate should be max 3°C/s, and the time above 217°C should be limited to 60-120 seconds.
Q: How do I select the correct bin code for my design? A: You must specify three codes: Brightness (e.g., H6 for 8-10 LM), Voltage (e.g., N13-4 for 3.0-3.2V), and Color Temperature (e.g., UW11-10 for 6500-7000K). This ensures visual uniformity in your light fixtures.
Q: Does this LED comply with environmental regulations? A: Yes, the datasheet explicitly states the product complies with ROHS directives, ensuring it is free from hazardous substances suitable for global markets.
