IR emitters and photodiodes are AEC-Q101-qualified

Offering an ultra-wide ±75° angle of half-intensity, Vishay has introduced two matched pairs of high-speed AEC-Q101-qualified 940nm IR emitters and silicon PIN photodiodes. The VSMB10940X01/VEMD10940FX01 feature a profile of 1mm while the VSMB11940X01/VEMD11940FX01 offer a profile of 0.6mm. The company claim that this is the industry's lowest profile for side-looking, AEC-Q101-qualified components.

With their low profiles, the VSMB10940X01/VEMD10940FX01 and VSMB11940X01/VEMD1194FX01 are optimised for use in IR touch panels for devices such as printer displays, eBook readers, smartphones, tablets and ultrabooks, as well as automotive interior touch displays for multimedia and navigation. With their 0.6mm profile, the VSMB11940X01/VEMD11940FX01 allow for slimmer designs in these products while the larger photosensitive area of the VSMB10940X01/VEMD10940FX01 enables higher signal output.

Offered in clear, untinted plastic packages, the VSMB10940X01 and VSMB11940X01 IR emitters feature GaAIAs multi quantum well technology. The devices provide high radiant intensity of 1mW/sr typical at 20mA, low forward voltage of 1.3V at 20mA, and fast switching times of 15ns.

The VEMD10940FX01 and VEMD11940FX01 photodiodes feature a daylight blocking filter matched with 830nm to 950nm IR emitters, and they offer reverse light current of 1.1µA and 3µA, respectively. Both devices provide high radiant sensitivity from 780+1050nm, low dark current of 1nA, and 950nm wavelength of peak sensitivity.

The VSMB10940X01/VEMD10940FX01 and VSMB11940X01/VEMD1194FX01 provide a floor life of 168 hours and moisture sensitivity level of 3 in accordance with J-STD-020. RoHS-compliant, halogen-free, and Vishay Green, the emitters and photodiodes support lead (Pb)-free reflow soldering.

Supplied in compact 3x2mm side-view surface-mount packages, samples and production quantities of the IR emitter/photodiode pairs are available now, with lead times of 8-10 weeks.
