VSMA Series High-Power IR Emitters deliver 30% higher radiant intensity


Vishay’s IR emitters deliver 30% higher radiant intensity in a 20% smaller footprint

Vishay’s optoelectronics portfolio now includes six 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, these devices are designed for high drive currents up to 1.5 ADC and 5 A pulsed in industrial and consumer applications.

The sensors provide 30% higher radiant intensity 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.

  • Centroid wavelengths of 850 nm and 940 nm
  • Feature a double-stack chip for high radiant intensity up to 6,000 mW/sr at a 5 A pulse current
  • Three angles of half intensity available: 28°, 40°, and 60°
  • Increased ambient temperature range from -40°C to +125°C
  • Low thermal resistance from 6 K/W to 9 K/W
  • RoHS-compliant, halogen-free, and Vishay Green
  • Support lead (Pb)-free reflow soldering
  • High ESD immunity up to 5 kV in accordance with ANSI/ ESDA/ JEDEC® JS-001
  • Floor life of 168 hours
  • Moisture sensitivity level of 3 in accordance with J-STD-020E
