Vishay releases high-power, high-speed 850 nm, and 940 nm infrared emitters in gullwing, reverse gullwing, and side-view SMD packages. They include wide angles of half-intensity and radiant intensity to 35 mW/sr. Saving space over lensed PLCC2 solutions, the IR emitters are available in compact top-view 2.3 mm x 2.3 mm x 2.5 mm gullwing and reverse gullwing packages, and 2.3 mm x 2.55 mm x 2.3 mm side-view packages. Offering fast switching speeds and low forward voltages, the devices feature a GaAIAs surface emitter chip (VSMY2853), and multi-quantum well (VSMB2943, VSMB2948) technologies.
