📌 Product Overview
The XL-1608SYGC-06FB is a standard 0603 (1608 metric) Yellow-Green SMD LED designed by XINGLIGHT for general indication and backlighting purposes. 💡 It utilizes a transparent water colloid to provide a dominant wavelength of 570nm with a wide 120° viewing angle, making it ideal for uniform status indicators and dashboard illumination. For engineering teams, the critical selection variables are its low power consumption (20mA max) and compliance with industrial operating temperatures (-40°C to +85°C), ensuring stability in harsh environments.
🎯 Typical Applications & Design Context
Based on its 567-575nm wavelength and compact 1.6x0.8mm footprint, this component targets high-density board designs:
- Medical & Industrial: Endoscopes and electronic instrument panels benefit from the wide 120° viewing angle and consistent color temperature.
- Consumer & Smart Home: White appliances and router indicator lights utilize the low Vf (1.8-2.4V) for efficient power management.
- Automotive: Suitable for non-critical interior backlighting (key lights) where AEC-Q102 is not mandated, but reliability is required.
📊 Key Technical Specifications
👇 The table below summarizes the optical and electrical performance windows essential for driver circuit design.
| Parameter | Symbol | Min | Typ | Max | Unit | Conditions |
|---|---|---|---|---|---|---|
| Luminous Intensity | Iv | 50 | - | 120 | mcd | IF = 20mA |
| Dominant Wavelength | λd | 567 | 570 | 575 | nm | IF = 20mA |
| Forward Voltage | Vf | 1.8 | - | 2.4 | V | IF = 20mA |
| Viewing Angle | 2θ1/2 | - | - | 120 | deg | IF = 20mA |
| Reverse Voltage | Vr | - | - | 5 | V | - |
✨ Note: Bin codes (D1/D2 for Brightness, M17-9 to M18-5 for Voltage) must be strictly managed in BOM to ensure visual uniformity in mass production.
⚠️ Absolute Maximum Ratings & Process Limits
Exceeding these parameters creates immediate failure risks. ⚠️ ESD Sensitivity is 2000V; improper handling during PCB assembly can cause latent damage or immediate death.
| Parameter | Symbol | Max Value | Unit | Notes |
|---|---|---|---|---|
| Peak Forward Current | Ifp | 60 | mA | Pulse width ≤0.1ms, Duty ≤1/10 |
| Power Dissipation | Pd | 50 | mW | Derating required above 25°C ambient |
| Operating Temperature | Topr | -40 ~ +85 | °C | Industrial range |
| Storage Temp | Tstg | -40 ~ +85 | °C | |
| Soldering Temp | Tsol | 260 | °C | ≤ 6 Seconds (Manual) |
🔒 SMT Validation: The datasheet specifies MSL Level 3. 🚨 Floor life is limited to 168 hours after opening the bag. Baking is required (125°C for 24-48 hours based on floor life exposure) before reflow to prevent "popcorning" delamination.
🧩 Package, Dimensions & Assembly Notes
- Package: 1608 Metric (EIA standard).
- Dimensions: 1.6mm (L) x 0.8mm (W) x 0.6mm (H).
- Soldering Guidance: Designed for standard SMT automation. While manual soldering is allowed (260°C < 6s), wave soldering is generally not recommended for plastic LED packages due to thermal shock risk. Reflow profiles should adhere to the 125°C (max 150s) / 183°C (60-150s) preheat and soak limits mentioned in reliability testing.
🔍 Procurement & Sourcing Insights
- Supply Chain Risk: As a catalog component, availability is generally stable, but bin consistency (color and voltage) varies by production batch.
- Alternative Strategy: When validating alternatives (e.g., Everlight, Lite-On), prioritize the Forward Voltage (Vf) bin match to prevent current resistor mismatch, and verify the Dominant Wavelength to ensure the "Yellow-Green" hue matches the UI design intent.
- Traceability: For medical applications (endoscopes), ensure the supplier provides a Certificate of Compliance (CoC) confirming RoHS adherence and MSL 3 baking procedures.
❓ FAQ
Q: What happens if I exceed the 60mA peak current?
A: Exceeding the pulse current limit (60mA) or duty cycle will overheat the LED die, potentially degrading the phosphor/colloid or causing immediate bond wire failure.
Q: Can I use this LED in a 3.3V indicator circuit?
A: No. The forward voltage is 1.8V-2.4V. Connecting directly to 3.3V without a current-limiting resistor will cause catastrophic failure. You must calculate the resistor value: $R = (V_{source} - V_{led}) / I_{led}$.
Q: Does MSL 3 require dry packing?
A: Yes. The moisture sensitivity level is 3. Components must be shipped in vacuum-sealed bags with desiccant. If the vacuum is broken, the components must be baked prior to reflow soldering to avoid moisture-induced cracking.
Q: Is this component suitable for automotive exterior lighting?
A: No. While listed under "Automotive Electronics," it is intended for interior indicators (key lights/backlight). It lacks the specific AEC-Q102 qualification and lumen output required for exterior signal lights (headlights/taillights).
