A physicist has made the best ever p-n junction diode from a carbon nanotube. The current-voltage characteristics of the device exhibit an "ideality factor" of one, which is the maximum possible value ...

Santa Clara, CA — National Semiconductor launches its newest laser diode driver (LDD) for use in optical pickup units (OPUs). The LMH6533 has extremely fast switching rates and very low output current ...

Zetex has announced a synchronous rectifier controller for flyback converters. Combined with a discrete power Mosfet, the ZXGD3101T8 ‘zero point detector driver’ replaces Schottky and other diodes to ...

Compact laser-diode arrays that emit more than 1 kW and are far easier and cheaper to package than conventional diode stacks could result from a new technology being pioneered by a US start-up.
