Description
SST-20-WS Gen 2 High Power White LEDs
Features
• The high power cool white LEDs have a typical output of 1100 lm @3 A, 85°C.
• The vertical chip delivers high lumen density and small emitting angle, ideal for maximizing the intensity and beam distance in directional lighting.
• The phosphor-on-chip technology features high color uniformity over radiation angle, enabling superior light quality for beam spots.
• Maximum Drive Current: 3 A
• Color Temperature: 5000K, 5700K, 6500K
• Color Rendering Index: Typ. 70, Min. 65
• Low thermal resistance: 1.6°C/W
• ANSI-compatible chromaticity bins
• Available in 2 soldering footprint configurations
• Electrically isolated thermal path
• 8 kV HBM ESD rating per ANSI/ESDA/JEDEC JS-001
Applications
• Portable Lights
• Bicycle Lights
• Automotive Auxiliary Lights
• LED Work Lights
• Outdoor and Roadway Lighting
• High Bay Industrial Lighting
