📌 Product Overview
The XL-2106SYGC is a standard 0805 (2012 metric) Surface Mount Device (SMD) LED designed by XINGLIGHT. It features a High-Brightness Yellow-Green emission with a dominant wavelength of 565–575nm. Targeting global OEM and EMS manufacturing lines, this component is optimized for high-volume automated assembly (SMT) and reflow soldering processes. For engineering teams, the critical selection variables are its low forward voltage (min. 1.8V) and wide 120° viewing angle, making it ideal for status indicators and backlighting where uniform light diffusion is required on compact PCBAs.
🚀 Typical Applications & Design Context
Based on its robust industrial temperature range (-40°C to +85°C) and moisture sensitivity level (MSL 3), the XL-2106SYGC is best suited for:
- Consumer Electronics & Home Appliances: Power indicators and user interface panels due to low power consumption (20mA standard).
- Automotive Electronics (Interior): Dashboard indicators (non-critical lighting) where high-brightness visibility is needed.
- Industrial PCBA & Traffic Indication: Status lights requiring high reliability under thermal stress.
- Toys & Giftware: Cost-effective lighting solution with RoHS compliance for international markets.
The component is specifically designed for SMT automation, ensuring pick-and-place compatibility for high-speed mass production environments.
📊 Key Technical Specifications
The following data highlights the performance windows under standard test conditions (Ta=25°C, IF=20mA). These parameters are critical for driving circuit design and brightness consistency.
| Parameter | Symbol | Min. | Typ. | Max. | Unit | Test Conditions |
|---|---|---|---|---|---|---|
| Luminous Intensity | Iv | 50 | - | 80 | mcd | IF = 20mA |
| Dominant Wavelength | λd | 565 | - | 575 | nm | IF = 20mA |
| Forward Voltage | VF | 1.8 | - | 2.4 | V | IF = 20mA |
| Viewing Angle | 2Ø1/2 | - | - | 120 | Deg | IF = 20mA |
| Reverse Voltage | VR | - | - | 5 | V | IR ≤ 5μA |
Note: Binning codes (D1/D2 for brightness, HYG03-06 for wavelength, M17-9 to M18-5 for voltage) allow for tighter supply chain control if specified during procurement.
⚠️ Absolute Maximum Ratings & Process Limits
Exceeding these parameters risks immediate catastrophic failure or latent degradation (reliability decay).
| Parameter | Symbol | Value | Unit |
|---|---|---|---|
| Max Power Dissipation | PD | 50 | mW |
| Max Continuous Forward Current | IF | 20 | mA |
| Peak Forward Current | IFP | 80 | mA |
| ESD Susceptibility | ESD | 2000 | V |
| Operating Temperature | TOPR | -40 ~ +85 | °C |
💡 E-E-A-T Insight:
The MSL (Moisture Sensitivity Level) is 3.
- Risk: If the floor life (exposure time) exceeds 168 hours before reflow, internal "popcorning" or delamination can occur during the high-heat soldering process.
- Action: Procurement must verify that suppliers bake the reels if the vacuum seal is broken for more than 1 week prior to SMT.
📐 Package, Dimensions & Assembly Notes
- Package: 0805 (Metric 2012). Dimensions: 2.1 (L) x 0.55 (W) x 1.0 (H) mm.
- Soldering: Compatible with standard Infrared Reflow.
- Lead-Free Process: Max temp 260°C. Peak temperature should not exceed 255°C for >5-10 seconds.
- Manual/Repair: soldering temp ≤ 260°C for ≤ 6 seconds.
- Placement: The "water clear colloid" lens provides a wide viewing angle but requires correct polarity orientation during tape-and-reel setup.
🔒 Procurement & Sourcing Insights
- Supply Chain Risk: As a standard commodity LED, the XL-2106SYGC faces high substitution risk from the "gray market" (Huaqiangbei).
- Traceability: LDeepAI recommends verifying the original packaging (EIA standard Reel) to avoid mixed batches where brightness (IV) or Forward Voltage (VF) binning codes are inconsistent.
- Alternative Validation: When validating alternatives (e.g., Everlight, Lite-On), ensure the footprint dimensions (specifically the 1.0mm height) do not conflict with adjacent components or shield cans.
- Quality Control: Always request the "Reliability Test Report" (MIL-STD-750D compliant) for批次 (batches) intended for automotive or safety-critical applications.
❓ FAQ
Q1: What are the critical failure modes if I drive the LED at 30mA continuously?
A: While the pulse current can handle 80mA, continuous operation above 20mA exceeds the Absolute Maximum Rating. This will accelerate thermal decay of the phosphor/epoxy, leading to permanent lumen depreciation (dimming) and potential junction breakdown.
Q2: Can I use this for lead-free soldering profiles?
A: Yes, the datasheet explicitly supports lead-free processes up to 260°C. However, ensure the MSL 3 preconditioning (baking) is strictly followed to prevent moisture-induced cracking during the higher peak temperatures of lead-free profiles.
Q3: How does the "D1/D2" brightness grading affect my procurement?
A: If you do not specify the bin code (e.g., D1), your supplier may ship mixed batches. On a single PCBA panel, this will result in visible uneven brightness between LEDs. For mass production, lock the bin code with your vendor.
Q4: Is this LED suitable for outdoor traffic signals?
A: While the datasheet lists "Traffic instructions," this specific component (Yellow-Green, 570nm) is an indicator LED. It is likely not intense enough for high-intensity traffic signal lamps (which typically require high-power emitters). Verify luminous intensity (Iv) against local regulatory standards before designing.
