Vishay Intertechnology Introduces New High-Speed 850 nm and 940 nm IR Emitters
and Package-Matched High-Speed Silicon PIN Photodiode for
Infrared Touch Panels
Devices Offer +/-75 Deg. Angle of Half Intensity in Compact 3 mm by 2
mm by 1 mm Side-View Surface-Mount Package
MALVERN, PA -- (Marketwired) -- 05/14/13 -- Vishay Intertechnology,
Inc. (NYSE: VSH) today broadens its optoelectronics portfolio with
the introduction of two new high-speed 850 nm and 940 nm infrared
emitters and a package-matched high-speed silicon PIN photodiode with
high radiant sensitivity from 780 nm to 1050 nm. The VSMG10850,
VSMB10940, and VEMD10940F offer an ultra-wide +/- 75 degrees angle
of half intensity in a compact side-view surface-mount package
measuring 3 mm by 2 mm and a height of only 1 mm.
Offered in clear, untinted plastic packages, the IR emitters released
today provide high radiant intensity of 1 mW/sr typical at 20 mA, up
to 33% higher than comparable devices on the market, and fast
switching times of 15 ns. The 940 nm VSMB10940 features GaAIAs multi
quantum well technology and a low forward voltage of 1.3 V typical
while the 850 nm VSMG10850 offers GaAIAs double hetero technology and
a forward voltage of 1.4 V.
The VEMD10940F photodiode features a daylight blocking filter matched
with 830 nm to 950 nm IR emitters, including the VSMG10850 and
VSMB10940. The device offers a reverse light current of 3 microamps,
low dark current of 1 nA, 920 nm wavelength of peak sensitivity, and
a low 0.1 %/K temperature coefficient of light current.
With their low profiles, the VSMG10850, VSMB10940, and VEMD10940F are
optimized for use in IR touch panels for devices such as printer
displays, eBook readers, smartphones, tablets, ultrabooks, and GPS
units. The devices provide a floor life of 168 hours and moisture
sensitivity level (MSL) of 3 in accordance with J-STD-020. The
emitters and photodiode support lead (Pb)-free reflow soldering and
conform to Vishay's "Green" standards.
Samples and production quantities of the new IR emitters and
photodiode are available now, with lead times of six to eight weeks.
