Malvern, Pa. Vishay Intertechnology has expanded 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 offers a viewing angle of +/-38°, which enables significantly better performance than standard 5-mm emitters, Vishay said.
The combination of a wide viewing angle, high-power output up to 1 A, and high speed makes the TSFF5510 infrared emitter well-suited 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.
Touting 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, Vishay said. The device features a switching time of 15 ns, meeting the requirements for high-modulation operation of 23 MHz, and supporting data transmission rates of up to 16 Mbits/s.
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 and RoHS directives.
Pricing: $0.45 in quantities of 100 for U.S. delivery.
Availability: Samples and production quantities are available now, with lead times of four weeks for large orders.
