Vishay's New 3-mm High-Power, High-Speed 940-nm Infrared Emitter Delivers Equal Performance to 5-mm Devices with High Radiant Intensity of 65 mW/sr and Optical Power of 40 mW at 100 mA

(PresseBox) (Malvern, Pennsylvania (USA) , ) Vishay Intertechnology, Inc. (NYSE: VSH) today broadened its optoelectronics portfolio with the introduction of a 3-mm (T1) infrared emitter with performance characteristics comparable to leading 5-mm emitters.

The new VSLB3940 940-nm infrared emitter features an on-axis radiant intensity of 65 mW/sr and optical power of 40 mW at 100 mA - which represents about an 8% performance improvement over the larger, 5-mm TSAL6200 in a 40% smaller form factor.

The small size of the VSLB3940 makes it an excellent choice for the compact infrared (IR) remote control units used with digital cameras, notebook PCs, and MP3/video players. Until now, the 3-mm emitters available for these miniaturized remote controls have forced designers to trade away performance for space savings, particularly when it came to transmit distance and off-axis radiant intensity. The new VSLB3940 eliminates this tradeoff, giving designers the performance they need and the space savings enabled by a 3-mm component size.

The VSLB3940 is a high-speed emitter with switching times of 15 ns. It can support data rates up to 30 Mbit/s. It features an angle of half intensity of ±22° and a forward voltage of 1.35 V at 100 mA. In addition to remote control applications, the VSLB3940 can be used for wireless communication, optical counters, card readers, and light barrier or interrupter applications.

Samples and production quantities of the VSLB3940 IR emitter are available now, with lead times of four to six weeks for large orders.
