Vishay has broadened 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 is said to enable 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 suitable 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 1,45 V at 100 mA and 2,15 V at 1 A, the TSFF5510 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 Mbps.
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 pitch of 2,54 mm. The emitter is a lead-free component in accordance with WEEE 2002/96/EC and RoHS 2002/95/EC.
