SiC MOSFET structure reduces resistance and boosts energy efficiency in power devices
Hitachi Ltd. says it has developed a new kind of silicon-carbide-based MOSFET that has dramatically lower on resistance than comparable devices. The new MOSFET uses what Hitachi calls a TED-MOS structure, for Trench-etched DMOS-FET. Compared to conventional DMOS-FET (Double-diffused MOSFET) devices, the new structure is said to reduce electric field strength, an index of durability […]
Power choke for automotive apps handles 54 A currents
Würth Elektronik eiSos expands its portfolio of AEC-Q-qualified products with the WE-CHSA power choke high current inductor. The patented ferrite core design of the new power choke has an air gap optimally centered to ensure a precisely defined saturation current. WE-CHSA can be used in the extended temperature range of 55 up to +150°C. The patented […]
Ground fault sensor monitors 100-A circuits with large sensing window
NK Technologies released the AGT-FD Series, new ground fault sensors that detect faults to earth from 0 mA to 100 mA and produce an output signal of 0–10 VDC in proportion to the amount of current passing to ground. The output is equal to the RMS value of the earth leakage. The AGT’s sensing window is […]
Now that’s a wide bandgap: Could gallium oxide be the next power transistor technology?
Researchers at the University of Buffalo have come up with a MOSFET made from the unusual material gallium oxide. The point of the work is that gallium oxide has a bandgap of about 4.8 eV, better than that of SiC’s 3.4 eV or GaN at 3.3 eV or silicon at 1.1 eV. Bandgap measures the […]
Vitreous enamel-coated tubular wirewound resistors handle load-dump apps
Stackpole’s EWT series of vitreous enamel coated tubular wirewounds is a good choice for high power load dump applications. It is available in power ratings from 25 to 300 W. The vitreous enamel coating withstands temperatures of up to 500°C and allows operating temperatures up to 350°C. The EWT’s robust wire element withstands thousands of […]
