Advanced thin-film technology beefs up LED performance Product News 11/30/2005 Post a comment OSRAM Opto Semiconductors Inc. has made significant improvements to its proprietary thin-film technology that have resulted in enhancements to the luminous efficacy and color palette of its Power TOPLED line of light-emitting diodes (LEDs) for automotive, signal and signage applications. The new Power TOPLED products are said to offer 150 percent greater efficiency and produce a wide variety of red and yellow tones. In addition, the new devices offer all the benefits of surface-mount technology
Phototriacs feature a low trigger current Product News 11/22/2005 Post a comment Vishay Intertechnology, Inc. has unveiled a new line of phototriacs that feature a low trigger current of 1.6 mA, which the company said is lower than any other competitive device. The new devices also provide a static dV/dt greater than 5 kV/microsecond.
IBM claims better LED News & Analysis 11/17/2005 Post a comment IBM Corp. unveiled what is said is the world's first electroluminescent nanotube transistor and claimed it glows 1,000 times brighter than a light-emitting diode.

Infrared phototransistors shrink in size Product News 11/3/2005 Post a comment Now available in a 1206 case size, TT electronics OPTEK Technology's new series of NPN silicon transistors are designed for infrared detection in sensing applications. The new miniaturized surface-mount OP520/OP521 series devices tout fast response times of 15 microseconds for machine automation, miniature optical encoders and other high-speed, non-contact position sensing systems.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
