Vishay IR Diodes Offer Powerful light in surface mount Package
Vishay Intertechnology is broadening its optoelectronics portfolio with the introduction of two new SurfLight high-speed infrared (IR) emitting diodes in compact 3.2 mm by 1.6 mm by 1.1 mm surface-mount, top-view packages.
Based on Vishay's GaAIAs surface emitter chip technology, the 850 nm VSMY12850 and 940 nm VSMY12940 combine high radiant intensity and optical power with fast switching times.
The IR emitters are offered in clear untinted PCB-based packages with inner lenses for surface mounting. Offering lower profiles than devices with dome lenses or PLCC-2 packages, the VSMY12850 and VSMY12940 provide powerful IR illumination in space- constrained end products. When used with Vishay's VCNL sensor family, the emitters are optimised for proximity and gesture applications, wake-up functions, optical switches, and photointerruptors and IR emitters for 3D gaming units and IR touch panels.
The VSMY12850 and VSMY12940 offer radiant intensity to 16 mW/sr at a low 70mA driving current, fast switching times of 10ns, and forward voltage of 1.6 V. Suitable for high pulse current operation to 1 A at 100 Âµs, the devices feature a Â± 40Â° angle of half intensity and operate over a temperature range of -40degC to +8degC.
