Vishay High-Speed, Surface-Mount IR Emitters offered by TTI



TTI, Inc., is now stocking the VSMY5940/5850 family of High-power IR LEDs from Vishay. These compact LED products are targeted for industrial, security illumination and medical sensing applications requiring focused light emission.

Vishay has now broadened its optoelectronics portfolio with the release of new high-speed, infrared (IR) emitters in a 2mm by 1.25mm by 0.8mm 0805 surface-mount package, the industry’s smallest package to offer opaque side walls. Built on Vishay’s SurfLight surface emitter chip technology, the Vishay Semiconductors VSMY5850X01 (850 nm), VSMY5890X01 (890 nm) and VSMY5940X01 (940 nm) deliver 30 percent higher radiant intensity than previous-generation devices over a wide temperature range from -40° C to +110° C. All are compliant to AEC-Q101 guidelines, offer a floor life of 168 hours and feature a moisture sensitivity level of 3.

Unlike standard IR emitters that emit light in all directions, the SurfLight VSMY5850X01, VSMY5890X01 and VSMY5940X01 emit nearly all of their light and power out of the top of the chip. With most of the light concentrated on the surface, the IR emitters achieve higher intensity to 13 mW/sr for proximity sensors, optical switches and miniature light barriers. The devices combine their high brightness with a ± 60° angle of half intensity, fast rise and fall times of 7 ns and low forward voltages down to 1.6 V at 100 mA.
