## 📌 Product Overview
The XL-5730SURC-05 is a 0.5W high-brightness red SMD LED manufactured by XINGLIGHT, utilizing a standard 5730 footprint (5.7x3.0mm) for broad compatibility with automated assembly lines. It targets commercial lighting, LCD backlights, and signage where consistent luminosity and compact form factors are critical. 💡 Designers must prioritize the component's thermal dissipation requirements and Moisture Sensitivity Level (MSL 3) to prevent degradation during infrared reflow soldering.
## 🎯 Typical Applications
Based on its optical characteristics and robust 120-degree viewing angle, the XL-5730SURC-05 is suitable for the following scenarios:
- General Illumination: Fluorescent tubes, rigid light strips, and downlights requiring uniform red tinting.
- Commercial & Signage: Advertising lightboxes, channel letters, and display panels needing high-intensity emission.
- Consumer Electronics: LCD backlights and indicator lights.
- Decorative Lighting: Flexible strip lighting for accent or mood applications.

⚠️ Soldering Limit: Max 260°C for ≤6 seconds (Manual soldering). For Infrared Reflow, ensure profiles comply with MSL 3 pre-baking requirements to prevent popcorn cracking.
## 📦 Package, Dimensions & Assembly Notes
The component uses the industry-standard 5730 SMD package with a water-clear lens formulation optimized for red light transmission. The physical dimensions are 5.7mm (L) x 3.0mm (W) x 0.8mm (H). This footprint supports high-density SMT placement, making it ideal for modern automated production lines. The EIA-standard packaging ensures compatibility with most feeders. 👇 Designers should verify the pad layout matches the 5.7x3.0mm footprint to avoid tombstoning during the cooling phase of the reflow profile.
## 🚢 Sourcing & Supply Considerations
To ensure supply chain optimization and reduce sourcing risks:
- Verify Bin Codes: Cross-reference the Brightness (H6-H9), Voltage (N12-7 to N12-9), and Wavelength (HR01-HR03) bins against your design tolerances.
- Authenticity Check: Procure through authorized channels to guarantee ROHS compliance and avoid off-spec components that affect thermal performance.
- Sample Evaluation: Request pre-production samples to validate the CRI (Color Rendering Index) consistency in your specific optical assembly.
## ❓ Frequently Asked Questions
Q: What is the recommended reflow soldering profile for the XL-5730SURC-05?
A: The LED is suitable for standard infrared reflow. For lead-free processes, the peak temperature should not exceed 255°C, with time above 217°C (TAL) strictly controlled between 60-120 seconds. Ensure the ramp-up rate does not exceed 3°C/second to minimize thermal shock.
Q: How does the Moisture Sensitivity Level (MSL) affect storage and handling?
A: This component is classified as MSL 3. If the moisture barrier bag has been opened, components must be baked (per J-STD-033) before reflow if the floor life exceeds 168 hours to prevent internal delamination.
Q: Can I drive this LED at 300mA continuously?
A: No. The Max Continuous Forward Current is 150mA. The 300mA rating applies only to pulse conditions (pulse width $\le 0.1\text{ms}$, duty cycle $\le 1/10$). Continuous operation at 300mA will likely cause immediate thermal failure.
Q: What does the "water clear colloid" specification imply for the design?
A: It refers to the transparent epoxy encapsulation used for the LED lens. Unlike diffused lenses, this maximizes light output and intensity but results in a narrower, more focused beam pattern (120 degrees), which is ideal for light mixing chambers but may require diffusers for direct-view applications.
