New Vishay Intertechnology High Power IR Emitters Deliver 30 % Higher Radiant Intensity in 20 % Smaller Footprint
February 14 2022 - 11:00AM
Vishay Intertechnology, Inc. (NYSE: VSH) today broadened 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 3.4 mm by 3.4 mm surface-mount packages. Built
on Vishay’s SurfLight™ surface emitter chip technology, the Vishay
Semiconductors 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 released today
provide high radiant intensity up to 6,000 mW/sr at a 5 A pulse
current. 30 % higher than previous-generation solutions and 10 %
higher than the closest competing device, these values enable
greater illumination distance while minimizing 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 ideal 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.
