Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the DURIS E 2835 LEDs from OSRAM Opto Semiconductors. Aimed at providing uniform, homogeneous light distribution, the DURIS E 2835 family are mid-power light-emitting diodes (LEDs) that combine good efficacy and a wide beam angle in an industry-standard 2835 (2.8 mm × 3.5 mm) footprint. The LEDs are ideal for retrofits and general indoor lighting designs in a variety of consumer and industrial applications.
OSRAM DURIS E 2835 LEDs are available from Mouser Electronics in two output versions of 0.2 W (3V) and 1.0 W (9V) to give designers choice of performance and cost. The 0.2 W LEDs feature higher luminous efficacy, as well as lower power dissipation and lower luminous flux. The 1.0 W LEDs feature higher luminous flux, lower luminous efficacy, and higher power dissipation. Both versions are housed in a compact surface-mount package and offer a wide 120-degree beam angle at 50 percent luminous intensity. The LEDs offer illumination color options of warm white, cool white, or neutral white (2700 K to 6500 K) with a minimum Color Rendering Index (CRI) of 80. The LEDs can withstand up to 2 kV of electrostatic discharge (ESD) voltage according to ANSI/ESDA/JEDEC JS-001 (HBM, Class 2). The 0.2 W LEDs are ideal for linear and area lighting fixtures and T8 tubes, and the 1.0 W LEDs are suited for lamps and consumer downlights and fixtures.
The 0.2 W LEDs feature typical luminous efficacy of 150 lm/W at 5000 K and luminous flux of 27 lm at 5000 K with forward voltage and current of 3.0 V and 60 mA. By contrast, the 1.0 W LEDs have lower luminous efficacy of 118 lm/W at 3000 K and higher typical luminous flux of 113 lm at 3000 K with a typical operating voltage of 9.6 V and forward current of 100 mA. Both versions offer an operating temperature range of minus 40 to 85 degrees Celsius and a junction temperature of 120 degrees Celsius.
