Built on Vishay's SurfLight surface emitter chip technology, the devices are designed for high drive currents up to 1.5 A DC and 5 A pulsed in industrial and consumer applications.
Featuring a double-stack chip, the IR emitters provide high radiant intensity up to 6,000 mW/sr at a 5 A pulse current. 30 % higher than previous-generation solutions, these values enable greater illumination distance while minimising the number of components required to lower costs and save space. For further space savings, the emitters occupy a 20 % smaller footprint than competing devices and previous-generation solutions.
The IR emitters are intended for eye tracking in gaming, as well as night vision for CCTV, machine vision, toll systems, number plate recognition, and general IR illumination. For these applications, the devices combine their high radiant intensity with three angles of half intensity — ± 28°, ± 40°, and ± 60° — an increased ambient temperature range from -40 °C to +125 °C, and low thermal resistance from 6 K/W to 9 K/W.
RoHS-compliant, halogen-free, and Vishay Green, the emitters support lead (Pb)-free reflow soldering. The devices offer high ESD immunity up to 5 kV in accordance with ANSI/ESDA/JEDEC JS-001, a floor life of 168 hours, and a moisture sensitivity level of 3 in accordance with J-STD-020E.
