Vishay VSMA10 series

Vishay’s SurfLight™ surface emitting technology is redefining performance standards for infrared emitters. With SurfLightTM, nearly all the light and power is emitted out the top of the chip, unlike standard infrared emitters that emit their light in all directions. With most of the light concentrated on the surface, you get higher intensity - up to five times greater than standard emitter technology - and that means fewer emitters are needed, lowering the total system cost of your application. With the new double stack VSMA10 series Vishay is extanding their currect portfilio and adding a new in a QFN package.
