Vishay’s New Infrared Emitters Built on Surface Emitter Technology Boost Radiant Intensity in 850 nm Devices Up to 100 mW/sr, with Optical Power Up to 55 mW
MALVERN, Pa. — April 6, 2011 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced a family of infrared emitters built on a surface emitter technology that enables the highest radiant intensity for this device type available on the market.
The surface emitter technology used in the new devices represents a unique die construction in which all the light generated inside the semiconductor is emitted through the top surface of the chip. The result is a 2.5X improvement in radiant intensity for the new family compared to devices in the same package types using conventional chip technologies.
By offering higher optical power in the same space, the new devices will allow designers to reduce component count and/or improve the performance of a host of applications using infrared emitters, which include 3DTV active glasses synchronization, infrared touch panels, CCTV security cameras, 3D imaging for gaming and surveillance, CMOS cameras and flashes, proximity sensors, light curtains, and data transmission.
The four surface-mount devices released today are offered in 0805 (VSMY1850), gull-wing dome lens (VSMY2850G), reverse gull-wing dome lens (VSMY2850RG), and PLCC-2 (VSMY3850) packages. They feature a peak emission wavelength of 850 nm, 10° or 60° angles of half intensity, and fast switching times of 10 ns. The following table summarizes their key specifications.
Key Device Specifications
|Device||Package type||Radiant intensity (mW/sr)||Angle of half intensity||Optical power (mW)||Forward voltage (V)||Moisture Sensitivity Level (MSL)|
|VSMY1850||0805 SMD||10||± 60°||50||1.65||3|
|VSMY2850RG||Reverse gullwing||100||± 10°||55||1.65||2a|
The new devices are all lead (Pb)-free, capable of lead-free soldering up to 260 °C, are halogen-free, and meet Vishay Green environmental specifications.
Samples and production quantities of the new emitters are available now, with lead times of 8 to 10 weeks for larger orders.
