Sumitomo Electric’s new generation of SiC transistors offer low on-state resistance
Sumitomo Electric’s new V-groove superjunction transistors, which it developed through a joint research project with the National Institute of Advanced Industrial Science and Technology (AIST) use silicon carbide (SiC) semiconductors, and the company claims they offer the lowest on-state resistance yet achieved in an SiC transistor. Sumitomo has already developed V-groove MOSFETs that use a… Read more »
ON Semiconductor announces rugged automotive SiC Diodes
ON Semiconductor has introduced a robust line of automotive-grade silicon carbide (SiC) Schottky diodes. The AEC-Q101 diodes can handle high surge currents and are meant to operate from -55° to 175° C. There are several reasons why SiC diodes are ideal for automotive applications. They are smaller and cheaper compared to alternatives, have higher power densities, and create… Read more »
Wolfspeed Technology introduces third-gen 1,200 V SiC MOSFET
Only one year after they were first introduced, Cree’s Wolfspeed Technologies has announced its third generation of 1,200 V SiC MOSFETs. Designed for EV powertrain applications, Wolfspeed claims that the MOSFET has the highest figure of merit on the market today, with low drain-source on resistance (RDS) performance and the industry’s lowest switching losses. Samples are currently available… Read more »
Infineon introduces new CoolSic Schottky diodes for on-board charger applications
Infineon Technologies’ new CoolSiC diodes are designed for ruggedness and efficiency, to meet the high standards required of hybrid and electric vehicles. Infineon says these diodes are the most durable on the market, due to their high corrosion and humidity resistance. The company will release CoolSiC Diodes in the 650 V class in September. An… Read more »
Littelfuse SiC MOSFET provides fast switching for power electronics
