🔑 Key Technical Specifications
The XL-1608 is specified under Ta=25°C conditions. It delivers a luminous intensity (Iv) ranging from 350 to 1000 mcd at a forward current (IF) of 20mA. Its dominant wavelength (λd) spans 515 to 535 nm, with a peak wavelength (λp) typically at 525 nm. The forward voltage (VF) is between 2.6V and 3.4V, and it features a wide 120° viewing angle (2Ø1/2) and a half-wave width (Δλ) of 30 nm, making it suitable for diffuse lighting applications.
⚠️ Absolute Maximum Ratings & Process Limits
Electrical and thermal limits are critical for design reliability. The maximum continuous forward current (IF) is 20 mA, with a peak pulse current (IFP) of 80 mA. The maximum reverse voltage (VR) is 5 V, and the device can withstand an ESD rating of 2000 V. Operating and storage temperatures range from -40°C to +85°C. For soldering, the lead temperature must not exceed 260°C for more than 6 seconds, ensuring compatibility with standard reflow profiles.
📦 Package, Dimensions & Assembly Notes
The XL-1608 utilizes a standard SMD package with outline dimensions of 1.6x0.8x0.4mm (L/W/H). It is compliant with EIA standard packaging and is designed for SMT automatic production. The component is suitable for infrared reflow soldering processes. With a Moisture Sensitivity Level (MSL) of 3, it requires standard moisture control procedures during storage and prior to reflow soldering to prevent popcorning or other assembly defects.
🚀 Sourcing & Supply Considerations
For mass production, ensure supply chain partners offer XL-1608 with consistent brightness and voltage binning grades. Verify adherence to RoHS compliance for environmental standards. Request samples to validate performance against your specific application's drive conditions and viewing angle requirements. Establish clear communication channels with suppliers to manage lead times and ensure authentic, high-quality components are sourced.
