9 /PRNewswire-FirstCall/ -- Ordinary silicon diodes
used in switched-mode power supplies lose up to 1% efficiency by not turning off immediately, but STMicroelectronics , a world leader in power semiconductors, is among the first companies to introduce silicon carbide (SiC) diodes that save this energy normally lost during switching.
Transients are diverted around the SP725 silicon diode
array input lines to the power supply rails (or ground).
However, when using a conventional or ultra-fast silicon diode
, this method is limited by power losses due to these diodes' reverse recovery.
SBDs can also act as replacements for silicon diodes
in switching power supplies, where they are much more efficient.
The Quint Diodes use MOSFETs, rather than Schottky or silicon diodes
used in most redundant power supplies.
Among specific topics are analyzing heterogeneous iron precipitation in multi-crystalline silicon, semi-insulating silicon for microwave devices, vacancies and self-interstitial dynamics in silicon wafers, optimizing silicon ingot quality by the numerical predicting of bulk crystal defects, dislocation states and deformation-induced point defects in plastically deformed germanium, hydrogenation in crystalline silicon materials for photovoltaic applications, characterizing semiconductor films epitaxially grown on thin metal oxide buffer layers, the scaling of quantum transport in silicon nano-transistors, and optimizing luminescence properties in silicon diodes
produced by implantation and annealing.
This has enormous potential in industry as the properties of diamond mean that it can switch voltages of up to 15,000 volts compared withthe 3,000-volt capacity of silicon diodes
Unlike ceramic devices, which have an inherent wear-out factor, SD05 and SD05C Series devices are made of silicon diodes
, which allows them to absorb repetitive ESD strikes or surge transients safely without performance degradation.
This means that the RJS6005TDPP SiC SBD can easily be used as a replacement for conventional silicon diodes
on existing printed wiring boards.
Patented energy-recovery circuit enables ultra-high efficiency using competitively priced silicon diodes
With the SemiSouth SiC JFET and diode portfolio, we will be able to address the main power conversion and inversion circuits in those same applications by replacing silicon diodes
, MOSFETS and IGBTs with higher-performance SiC technology.
