New High Power IR Emitters with SurfLight Surface Emitter Chip Technology designed for High Drive Currents in Industrial and Consumer Applications

Vishay Intertechnology has expanded its optoelectronics portfolio with the release of six new 850 nm and 940 nm high power infrared (IR) emitters that deliver best in class radiant intensity in 3.4mm by 3.4mm surface-mount packages. Built on Vishay’s SurfLight surface emitter chip technology, these devices are designed for high drive currents up to 1.5 A DC and 5 A pulsed in industrial and consumer applications. Moreover, these emitters are ideal for eye tracking in gaming, as well as night vision for CCTV, machine vision, toll systems, number plate recognition, and general IR illumination.

These devices combine their high radiant intensity with three angles of half intensity and an increased ambient temperature range from -40 °C to +125 °C, and low thermal resistance from 6 K/W to 9 K/W. Featuring a double-stack chip, these IR emitters provide high radiant intensity up to 6,000mW/sr at a 5A pulse current and enable greater illumination distance while minimizing the number of components required to lower costs and save space.
