Avago Technologies Introduces High-Power 870- and 940-Nanometer Infrared Emitter Family



5-mm Lamps Offer Up to 200 mW/sr Radiant Power, High-Speed, Low Forward Voltage and Cost Savings in Consumer and Industrial Applications

SAN JOSE, Calif., Jan. 9, 2006 -- Avago Technologies today introduced a family of high-power infrared (IR) LED emitters with 870- and 940-nanometer (nm) wavelengths in 5-mm (T-1 3/4) through-hole packages. These new IR emitters are fabricated using the company's high-power aluminum gallium arsenide (AlGaAs) LED technology, which has been optimized for high radiant intensity, speed and low forward voltage. The 5-mm packages are built with iron lead frames that dissipate power efficiently over a wide range of currents.

Avago's HSDL-42xx series IR emitters are specifically optimized to meet today's requirements for increased infrared transceiver link distances and higher data rates in consumer, industrial and communications applications. Such applications range from access controls and portable instruments, to IR optical mice and smoke detectors, to IR LAN transceivers and audio links. The 870-nm wavelength is commonly used for IR communications, and the 940-nm is typically used for remote-control applications.

"Manufacturers today need high-power, low forward voltage and high-speed infrared emitters as infrared transceiver link distance requirements and data rates continue to increase across all applications," said Chee-Kien Lim, infrared worldwide marketing manager for Avago Technologies' Optical Communication Solutions Division. "Our new family of infrared emitters meets and exceeds the needs of our customers."

Avago's HSDL-4250 and HSDL-4251 operate at 870-nm peak wavelength with low forward voltage of 1.4 V at 20 mA and optical rise and fall times of 40 ns. The HSDL-4250 features a typical on-axis intensity of 180 mW/sr (milliwatts per sterradian) with a 15-degree viewing angle. The HSDL-4251 features 100 mW/sr intensity and a 30-degree viewing angle. Intensities are measured at 100 mA forward current.

With an 875-nm peak wavelength, the Avago HSDL-4260 provides typical 200-mW/sr on-axis intensity at 100 mA, a 15-degree viewing angle, and 15-ns optical rise and fall time. Forward voltage is 1.4 V at 20 mA. Avago's HSDL-4270 and HSDL-4271 operate at 940-nm peak wavelength with a forward voltage of 1.3 V at 20 mA, and a 1.3-microsecond optical rise and fall time. The HSDL-4270 provides 100-mW/sr typical on-axis intensity and a 15-degree viewing angle. The HSDL-4271 provides 50-mW/sr intensity and a 30-degree viewing angle.

U.S. Pricing and Availability
