Vishay Electronic : 30 July, 2004  (New Product)
New devices target CMOS camera applications, automotive night-vision, and sensor systems

Two new infrared emitters aimed at CMOS camera and high-speed IR data transmission applications were launched today by Vishay Intertechnology, Inc.

The new high-speed, high-radiant power Vishay Semiconductors devices are optimized with an 850-nm wavelength to improve the optical efficiency of CMOS camera illumination systems compared with industry-standard 870-nm emitters. Typical applications for the new devices will include night vision systems and seat occupant sensors in vehicles, for which the 850-nm emitters offer the additional advantage of the low aging rate enabled by their GaAlAs double hetero technology.

These two 850-nm emitters were released today, each with a 20-ns rise time and low 1.8-V maximum forward voltage.

For applications where maximum radiant power and intensity are required, Vishay offers the TSHG6200 in the leaded T 1-3/4 package. Radiant intensity is 180 mW/sr at a forward current of 100 mA, while the 5-mm package provides a 10 angle of half intensity.

For applications where a device with a wider angle of intensity is preferred, Vishay is offering the TSMG3700 in the miniature PLCC-2 SMD package. This surface-mount emitter combines a 60 angle of half intensity with a radiant intensity of 10 mW/sr and is easily mounted to printed circuit boards using automatic placement equipment.

Both the TSHG6200 and TSMG3700 are lead (Pb)-free devices.

Samples of the new emitters are available now. Production quantities will be available in Q3 with lead times of 12 weeks for larger orders.
