📌 Product Overview
The XINGLIGHT XL-302SYGC is a 3mm diffused Through-Hole Technology (THT) LED designed for reliable indication in general-purpose circuitry. Housed in a white water-clear colloid, this device emits a standard Yellow Green light with a dominant wavelength of 570nm, making it ideal for dashboard lighting and signal status.
💡 This component is optimized for designs requiring low power consumption and straightforward assembly on PCBs or flexible wiring. It is fully ROHS compliant and supports standard DC drive logic.
🚀 Typical Applications
Based on its 30-degree viewing angle and moderate luminous intensity, the XL-302SYGC is best suited for indication rather than illumination.
- Consumer Electronics: Status indicators for home appliances and digital devices.
- Automotive: Dashboard signal lights and interior cabin indicators (non-critical).
- Industrial: Control panel status lights and communication equipment feedback.
- Education & Toys: Electronic teaching aids and electronic toy indicators.
- Urban Infrastructure: Traffic instruction signage and city lighting accents.
📊 Key Technical Specifications

| Reverse Current | IR | - | - | ≤10 | μA | VR = 5V |
💡 Design Note: The wide range in luminous intensity (50-300mcd) requires specific binning selection if visual uniformity is critical for the end product.
🔒 Absolute Maximum Ratings & Process Limits
Exceeding these ratings may cause permanent device failure. Design margins must account for these limits to ensure long-term reliability.
| Parameter | Symbol | Rating | Unit | Notes |
|---|---|---|---|---|
| Power Dissipation | Pd | 70 | mW | |
| Max Forward Current | IF | 20 | mA | Continuous DC |
| Peak Forward Current | IFp | 80 | mA | Pulse width/duty cycle limited |
| Operating Temperature | Topr | -20 to +85 | °C | Ambient range |
| Storage Temperature | Tstg | -40 to +85 | °C | |
| Soldering (Wave) | Tsol | 240 | °C | ≤ 6 seconds |
| Soldering (Manual) | Tsol | 300 | °C | ≤ 3 seconds |
⚠️ Critical Warning: Ensure the soldering point maintains a distance of at least 2.0mm from the bottom of the colloid to prevent thermal damage to the epoxy package.
📏 Package, Dimensions & Assembly Notes
The XL-302SYGC utilizes a standard F3 radial package with short leads, suitable for compact PCB layouts or manual wiring.
- Dimensions: The outer diameter is 3.0mm with a total length of 18mm.
- Tolerance: General dimensional tolerances are ±0.50mm unless otherwise noted.
- MSL Level: The component is classified at Moisture Sensitivity Level 2 (MSL 2).
- Assembly: It is packed in moisture-proof, anti-static foil bags to prevent damage prior to assembly.
- Mounting: Designed for wave soldering or manual insertion processes.
📈 Sourcing & Supply Considerations
When integrating the XL-302SYGC into BOMs, procurement teams should prioritize supply chain verification to avoid counterfeit risks common in standard LED commodities.
- Binning Codes: Verify specific Brightness (A1-A3), Voltage (N12-7 to N13-1), and Wavelength (HYG02-HYG06) codes to match design requirements.
- Authenticity: Source exclusively through authorized XINGLIGHT channels to guarantee ROHS compliance and optical consistency.
- Sample Support: Request pre-production samples to verify color binning and intensity matching for dashboard clusters.
❓ FAQ
Q: What is the typical forward voltage drop for this LED? A: The typical forward voltage (VF) is 2.2V at a forward current of 20mA. However, this can range from 1.8V to 2.6V depending on the specific binning grade.
Q: Can this LED be used for outdoor street lighting? A: While listed under "Urban lighting," this 3mm THT component is designed for indicator lights or decorative accents rather than high-power street illumination due to its maximum 300mcd intensity.
Q: What are the storage requirements to prevent moisture damage? A: The XL-302SYGC has an MSL of 2. It should be stored in a dry environment within -40°C to +85°C. The packaging uses anti-static foil bags to provide necessary moisture barrier protection.
Q: How close can the solder joint be to the LED body? A: The datasheet mandates that the welding point must be at least 2.0mm away from the bottom of the colloid to prevent heat damage during soldering operations.
Q: Is this component suitable for automotive dashboards? A: Yes, it is suitable for interior dashboard indicators. However, for exterior lighting or critical safety signals, engineers must verify specific automotive grade compliance and temperature derating.
