High Brightness Single Rank 1608-Size Chip LEDs
SML-D15 Series
Optimized design delivers stable
brightness with minimal variations
Product Outline
In automotive applications such as car audio and navigation systems, it is common to specify a particular
brightness rank in order to suppress brightness variations. ROHM developed the SML-D15 series using advanced
original process technology that enables stable production of single rank products, ensuring minimal brightness
variations in end applications.
■ Single Rank Advantages
■ Key Features
• 1608-size package
• Brightness variations minimized between individual LEDs in customer sets
• Single brightness rank offered
• 2-3x brighter than conventional products (SML-D12x8W)
• No need to select different resistances (for current control) for each rank,
significantly reducing design man-hours
• AEC-Q101 (automotive reliability standard) qualified
• No inventory management required for multiple ranks
• Eliminates the need specify ranks
