Vishay Vishay High-Power Infrared Emitters

Vishay's High-Power Infrared Emitter offers more wavelengths, like 830nm, 850nm, 870nm, 890nm, 940nm, and 950nm. These Infrared Emitters provide fast rise and fall response times and also have the broadest selection of double hetero infrared emitters. Vishay's high-power infrared emitters with the lowest forward voltages are ideal for high-current applications which provide high radiant intensities.
