XL-2214SYGC SMD LED Yellow Greeen Optical Thermal Design Guide

📌 Product Overview

The XL-2214SYGC from XINGLIGHT is a compact, surface-mount device (SMD) LED designed for high-density board integration. With a miniature footprint of 2.2x1.4x1.35mm, this component features a Yellow-Green luminous output (peak 572nm) housed in a transparent colloid for optimal light transmission.

💡 While primarily targeted at commercial lighting and LCD backlights, this component is engineered for automated SMT production. Designers should focus on its 120-degree viewing angle and low forward voltage (1.8V–2.4V) to balance power efficiency with wide-area illumination in indoor and decorative applications.

🚀 Typical Applications

Based on its optical characteristics and compact form factor, the XL-2214SYGC is best suited for the following scenarios:

  • Commercial & Signage: Ideal for advertising lightboxes and illuminated channel letters where consistent color temperature is vital.
  • Automotive Interiors: Suitable for dashboard indicators and soft ambient lighting within cabins.
  • Consumer Electronics: Effective for LCD backlights in small displays and status indicators.
  • Decorative Lighting: Designed for use in flexible light strips requiring a wide beam angle.

📈 Key Technical Specifications

👇 Design Insight: The wide viewing angle ($120^\circ$) makes this component ideal for diffused lighting applications rather than focused spotlights.

🔒 Absolute Maximum Ratings & Process Limits

Exceeding these parameters risks irreversible damage. Reliability testing ($1000Hrs$) confirms stability under these limits when adhering to storage and soldering standards.

⚠️ Critical Warning: Do not exceed the 260°C soldering temperature or the 6-second time limit to prevent epoxy delamination or chip damage.

📦 Package, Dimensions & Assembly Notes

  • Outline Dimensions: The package measures 2.2 x 1.4 x 1.35mm.
  • Tolerance: Standard dimensional tolerance is $\pm 0.25mm$ unless noted.
  • Moisture Sensitivity: Classified as MSL Level 3. Ensure proper baking before reflow if floor life is exceeded.
  • Soldering Guidelines:
    • Reflow: Designed for infrared reflow soldering. Use a Pb-Free profile (peak ~260°C) with a maximum of 2 reflow cycles.
    • Hand Soldering: Only for repair. Use an iron $<30W$ at $<300^\circ C$ for $<3$ seconds per joint.

Assembly Tip: This component utilizes EIA standard packaging, making it fully compatible with high-speed automated SMT pick-and-place machines.

🏗️ Sourcing & Supply Considerations

  • Supply Chain: Verify authenticity through authorized XINGLIGHT distributors to avoid counterfeits.
  • Bin Selection: This model utilizes specific grading codes for Brightness (D2-D4), Voltage (N12-7 to N12-9), and Wavelength (HYG03-HYG06). Specify these bins when ordering for uniform large-scale production.
  • Samples: Request pre-production samples with specific bin codes to validate color consistency in your specific optical housing.
  • Lead Time: Confirm stock availability for high-volume orders to prevent production line stoppages.

❓ FAQ

Q: What is the dominant wavelength of this LED?A: The typical dominant wavelength is 572nm (Yellow-Green), ranging from 565nm to 575nm depending on the specific wavelength bin (HYG03-HYG06).

Q: Can this LED be used for outdoor applications?A: The datasheet lists "Indoor lighting" and "Car interior." While the operating temperature range is wide (-40°C to +85°C), it is not specifically rated for IP-rated outdoor waterproof enclosures without additional protection.

Q: What are the soldering profile limitations?A: For reflow, do not exceed 2 cycles. For hand soldering, limit temperature to 300°C for 3 seconds maximum. Exceeding these limits compromises the internal bond wires.

Q: How is the brightness sorted?A: Brightness is sorted by codes such as D2 (80-120mcd) and D4 (150-180mcd). Selecting the correct bin code is crucial for maintaining visual uniformity across light panels.

Q: What does MSL Level 3 mean for assembly?A: It means the component can be exposed to ambient air for 168 hours (one week) before it must be reflowed. If exposed longer, it requires baking to drive out moisture to prevent "popcorning" damage during soldering.

Q: Is the forward voltage stable?A: The forward voltage ranges from 1.8V to 2.4V at 20mA. Design your driver circuit to accommodate the N12-9 bin (max 2.4V) to ensure consistent current regulation across all batches.
