Vishay launches new high-power infrared emitter with 30% higher irradiance and 20% smaller size

     Vishay Intertechnology, Inc. Announces Six New 3.4 mm x 3.4 mm Surface Mount 850 nm and 940 nm High Power Infrared (IR) Transmitters - VSMA1085250, VSMA1085400, VSMA1085600, VSMA1094250, VSMA1094400, and VSMA1094600, Irradiance Intensity Reach the advanced level of similar devices and further expand its optoelectronic product portfolio. The new Vishay semiconductor devices feature Vishay's SurfLight™ surface-emitter chip technology, drive currents up to 1.5A DC, and pulse currents up to 5A for industrial and consumer applications.

     The recently released infrared emitter adopts a double-layer chip, and the luminous intensity can reach 6000 mW/sr under 5A pulse current, which is 30% higher than the previous generation solution and 10% higher than the next competing device, thus extending the irradiation distance. , while minimizing component count, reducing cost and saving space. To further save space, the transmitter is 20% smaller than competing and previous-generation solutions.

     Infrared emitters are suitable for gaming eye tracking as well as CCTV, machine vision, toll systems, license plate recognition and general infrared lighting night vision. For these applications, the device has increased irradiance with three half-strength angles of ± 28°, ± 40° and ± 60°, ambient temperature -40 °C to +125 °C, and thermal resistance as low as 6K/W to 9K/W.

     The emitters are RoHS and Vishay Green compliant, halogen-free, and support lead (Pb)-free reflow soldering processes. The device has an ESD immunity of 5 kV, ANSI/ESDA/JEDEC® JS-001, a shelf life of 168 hours, and a moisture sensitivity level of J-STD-020E level 3.
