Supplied in 2.3 x 2.3 x 2.5 mm gullwing and reverse gullwing packages as well as 2.3 x 2.55 x 2.3 mm side-view packages, emitters offer switching speeds down to 10 ns.



Original Press Release:



Vishay Intertechnology Releases New High-Power, High-Speed 850 nm, 890 nm, and 940 nm Infrared Emitters in Gullwing, Reverse Gullwing, and Side-View SMD Packages



Offering Wide-View Dome Lenses, Devices Feature ± 25° and ± 28° Angles of Half Intensity and Optical Power to 35 mW/sr



MALVERN, Pa. — Vishay Intertechnology, Inc. (NYSE: VSH) is broadening its optoelectronics portfolio with the introduction of high-power, high-speed 850 nm, 890 nm, and 940 nm infrared emitters in gullwing, reverse gullwing, and side-view surface-mount packages with wide-view dome lenses.



VSMY2853, VSMF2893, VSMB2943, and VSMB2948 series devices consist of an adapted lens radius to provide wide ± 25° and ± 28° angles of half intensity. The resulting typical radiant intensities range from 20 mW/sr to 35 mW/sr at a 100 mA drive current. Saving space over PLCC2 solutions, the IR emitters are available in compact top-view 2.3 mm by 2.3 mm by 2.5 mm gullwing and reverse gullwing packages, and in 2.3 mm by 2.55 mm by 2.3 mm side-view packages.



Featuring GaAIAs surface emitter chip (VSMY2853), double hetero (VSMF2893), and multi quantum well (VSMB2943, VSMB2948) technologies, the devices are optimized for tablet IR touch panels, shutter glass synchronization in 3D TV applications, remote controls, light curtains, light barriers, metering systems, and external emitter sources for proximity applications. For automotive applications, the VSMB2943 and VSMF2893 are AEC-Q101-qualified.



The infrared emitters released today offer fast switching speeds down to 10 ns, low forward voltages down to 1.35 V at 100 mA, and operating temperatures from -40°C to +85°C. The devices ensure a four-week floor life and provide a moisture sensitivity level (MSL) of 2a in accordance with J-STD-020. The VSMY2853, VSMF2893, VSMB2943, and VSMB2948 series are compliant to RoHS Directive 2011/65/EU, halogen-free per JEDEC JS709A, and conform to Vishay's "Green" standards.
