Vishay Releases New High-Power, High-Speed 870-nm Infrared Emitter with Wide Viewing Angle of ±38° in Leaded Package
Device Offers Industry’s Lowest Forward Voltage of 1.45 V at 100 mA and 2.15 V at 1 A for Uniform Operation
MALVERN, Pa. — April 30, 2008 — Vishay Intertechnology (NYSE: VSH) broadens its optoelectronics portfolio with the introduction of its first wide-viewing-angle infrared emitter in a leaded package. With its uniquely designed lens, the TSFF5510 has a viewing angle of ±38°, which enables significantly better performance than standard 5-mm emitters.
The combination of a wide viewing angle, high power output up to 1 A, and high speed makes the TSFF5510 infrared emitter ideal for infrared audio and video data transmission in free-air data transmission applications with high modulation frequencies or high data transmission rates, such as infrared toll collection and wireless audio transmission systems. For example, many theatres and museums will use TSFF5510-enabled systems to comply with the Americans with Disabilities Act in providing infrared audio transmitters.
With the industry’s lowest forward voltage of 1.45 V at 100 mA and 2.15 V at 1 A, the TSFF5510 emitter provides the basis for very uniform operation performance, especially in a series circuit layout. The device features switching times of 15 ns, meeting the requirements for high-modulation operation of 23 MHz, and supporting data transmission rates of up to 16 Mbit/sec.
Suitable for high-pulse-current operation, the TSFF5510 offers a peak wavelength of 870 nm, 55-mW optical power at 100 mA, and radiant intensity of 32 mW/sr at 100 mA. The device offers a compact leaded package with a lens radius of 2.35 mm, a lens height of 3.8 mm, a lens width of 4.8 mm, epoxy bottom plane diameter of 5.9 mm, and a lead distance of 2.54 mm. The emitter is a lead (Pb)-free component in accordance with WEEE 2002/96/EC and RoHS 2002/95/EC
Samples and production quantities of the TSFF5510 are available now, with lead times of four weeks for large orders.
