Vishay broadens its optoelectronics portfolio with the introduction of a wide-viewing-angle infrared emitter in a leaded package. With its uniquely designed lens, the TSFF5510 has a viewing angle of ±38°, which enables better performance than standard 5-mm emitters. The combination of a wide viewing angle, power output up to 1A, and high speed makes the TSFF5510 infrared emitter dedicated 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. With a forward voltage of 1.45V at 100mA and 2.15V at 1A, the TSFF5510 emitter provides the basis for very uniform operation performance, especially in a series circuit layout.
The device features switching times of 15ns, meeting the requirements for high-modulation operation of 23MHz, and supporting data transmission rates of up to 16Mbit/sec. Suitable for high-pulse-current operation, the TSFF5510 offers a peak wavelength of 870nm, 55-mW optical power at 100mA, and radiant intensity of 32mW/sr at 100mA. The device offers a compact leaded package with a lens radius of 2.35mm, a lens height of 3.8mm, a lens width of 4.8mm, epoxy bottom plane diameter of 5.9mm, and a lead distance of 2.54mm. The emitter is a lead (Pb)-free component in accordance with WEEE 2002/96/EC and RoHS 2002/95/EC.
