📌 Product Overview
The XINGLIGHT XL-302SURD is a standard 3mm (F3) radial LED designed for through-hole PCB assembly. 💡 It features a Red diffused colloid and emits light at a dominant wavelength of 620nm (Red), making it suitable for general-purpose indication and backlighting. This component is engineered to meet ROHS compliance and offers a viewing angle of 30 degrees.
Target applications primarily include consumer electronics and industrial control panels. 👉 The design focus here is on providing a stable, high-efficiency light source with low DC drive requirements (2.2V typical) and long operating life, ensuring reliability in standard ambient temperature environments.
🚀 Typical Applications
Based on the 3mm F3 package size and optical characteristics, the XL-302SURD is optimized for the following scenarios:
- Industrial & Consumer Indicators: Status lights for home appliances (washing machines, air conditioners) and power supply units.
- Automotive Electronics: Interior dashboard lighting and non-critical instrument cluster indicators (subject to AEC qualification verification).
- Communication & Digital: Signal status indicators for routers, modems, and set-top boxes.
- Specialized Instruments: Electronic teaching equipment, digital clocks, and basic medical beauty device interfaces.

|---|---|---|---|---|
| Power Dissipation | Pd | 70 | mW | Derate above 25°C ambient |
| Max Forward Current | IF | 20 | mA | Continuous DC |
| Peak Forward Current | IFp | 80 | mA | Pulse width/duty cycle limited |
| Operating Temp. | Topr | -20 ~ +85 | °C | Ambient range |
| Storage Temp. | Tstg | -40 ~ +85 | °C | |
| Soldering (Wave) | Tsol | 240 | °C | ≤6 seconds duration |
| Soldering (Manual) | Tsol | 300 | °C | ≤3 seconds duration |
⚠️ Critical: The solder joint must be kept >2.0mm from the colloid bottom to prevent thermal damage to the epoxy resin.
📦 Package, Dimensions & Assembly Notes
The XL-302SURD utilizes the standard F3 (3mm) radial package with specific dimensions of 3.8x3.0x5.2mm (excluding leads).
- Moisture Sensitivity: The component is classified at MSL 2-3. Floor life should be managed accordingly, and baking is recommended if the moisture barrier bag is exposed beyond the specified limit.
- Assembly: Designed for wave soldering and manual welding processes. The "Short Leg" configuration assists with polarity identification during insertion.
- Tolerance: Dimensional tolerances are generally ±0.50mm unless otherwise noted, ensuring compatibility with standard lead forming equipment.
🛒 Sourcing & Supply Considerations
✅ When integrating the XL-302SURD into a new design, verify the specific binning codes (Brightness A5-A7, Voltage N12-7/8/9) with your distributor to ensure color and voltage consistency across batches.
- Supply Chain: XINGLIGHT utilizes EIA standard packaging, facilitating automated handling during SMT or THT processes.
- Verification: Always confirm that the "Red colloid" color temperature matches the UI requirements of your specific application.
- Samples: Request samples from LDeepAI to validate the brightness intensity (Iv) in your specific housing or light guide design.
❓ Frequently Asked Questions
Q: What is the forward voltage requirement for the XL-302SURD?
A: The typical forward voltage is 2.2V, with a maximum of 2.4V at 20mA. Ensure your driving circuit can supply a stable current within this voltage range to maintain consistent brightness.
Q: Can this LED be used for automotive exterior lighting?
A: While listed under "Automotive Electronics," this specific model is a standard radial LED. For exterior lights or safety-critical indicators, verify if it meets AEC-Q102 standards or requires a higher-specification automotive-grade component.
Q: What is the shelf life of the XL-302SURD?
A: The recommended storage period in the original moisture-proof packaging is up to 3 months at temperatures ≤30°C and humidity ≤70%. For longer storage, use a dry cabinet or nitrogen-filled environment.
Q: How close can the solder joint be to the LED body?
A: The datasheet specifies that the soldering point must be at least 2.0mm away from the bottom of the colloid to prevent heat damage during wave or manual soldering.
Q: What does "F3" mean in the model description?
A: "F3" refers to the standard 3mm round radial package size, a common industry standard for through-hole indicator LEDs.
Q: Is the XL-302SURD RoHS compliant?
A: Yes, the datasheet explicitly states that this is an environmental protection product meeting ROHS requirements, suitable for global markets.
