Vishay Intertechnology Inc. has expanded its TSAL series of infrared (IR) emitters with the introduction of its new TSAL6100X01, an emitter certified under the Underwriters Laboratories (UL) standard for Smoke Detectors for Fire-Protective Signaling Systems, or UL 268. The company said the device also provides a typical radiant intensity of 130mW/sr at 100mA, which is more than double that of standard emitters.

Like other devices in Vishay's TSAL series of IR emitters, the TSAL6100X01 offers a low forward voltage of 1.35V at 100mA and is suitable for high pulse-current operation. The UL-certified emitter features a high radiant intensity of 130mW/sr at 100mA and a narrow angle of half-intensity of 10. The company said because TSAL devices use GaAIAs on GaAs technology, emitters in the series produce more than 100% radiant power when compared to standard emitters at similar wavelengths.

For applications such as remote controls, which do not require this UL certification, the device is available under the same part number (TSAL6100). IR emitters in the TSAL series are lead-free and compatible with lead-free processing in accordance with the European Union's Waste Electrical and Electronic Equipment (WEEE) and Restriction of Hazardous Substances (RoHS) directives.

Samples and production quantities of the TSAL6100X01 UL 268-certified IR emitter are available now with lead times of six weeks. Pricing is 10 cents for U.S. delivery in quantities of 50,000.
