DULES, VA, Mayıs 13, 2015 — GeneSiC Semiconductor, a pioneer and global supplier of a broad range of Silicon Carbide (SiC) power semiconductors today announces the immediate availability of 20 mOhm-1200 V SiC Junction Transistor-Diodes in an isolated, 4-Leaded mini-module packaging that enables extremely low Turn-On energies losses while offering flexible, modular designs in high frequency power converters. The use of high frequency, high voltage and low on-resistance capable SiC Transistors and Rectifiers will reduce the size/weight/volume of electronics applications requiring higher power handling at high operating frequencies. These devices are targeted for use in a wide variety of applications including induction heaters, plasma generators, fast chargers, DC-DC converters, and switched mode power supplies.

Co-packaged SiC Junction Transistors (SJT)-SiC Rectifiers offered by GeneSiC are uniquely applicable to inductive switching applications because SJTs are the only widebandgap switch offers >10 microsec repetitive short circuit capability, even at 80% of the rated voltages (eg. 960 V for a 1200 V device). In addition to the sub-10 nsec rise/falls times and a square reverse biased safe operation area (RBSOA), the Gate Return terminal in the new configuration significantly improves the ability to reduce the switching energies. These new class of products offers transient energy losses and switching times that are independent of junction temperature. SiC Junction Transistors from GeneSiC are gate-oxide free, normally-off, exhibit positive temperature co-efficient of on-resistance, and are capable of being driven at low Gate voltages, unlike other SiC switches.
SiC Schottky Rectifiers used in these mini-modules show low on-state voltage drops, good surge current ratings and industry’s lowest leakage currents at elevated temperatures. With temperature independent, near-zero reverse recovery switching characteristics, SiC Schottky rectifiers are ideal candidates for use in high efficiency circuits.
“GeneSiC’s SiC Transistor and Rectifier products are designed and manufactured to realize low on-state and switching losses. A combination of these technologies in an innovative package promises exemplar performance in power circuits demanding wide bandgap based devices. The mini-module packaging offers great design flexibility for use in a variety of power circuits like H-Bridge, Flyback and multi-level inverters” said Dr. Ranbir Singh, President of GeneSiC Semiconductor.

Gate Driver Board optimized for high switching speeds and behavior-based models enable power electronic design engineers to verify and quantify benefits of SJTs in board-level evaluation and circuit simulation

DULES, V.A., Nov 19, 2014 — GeneSiC Semiconductor, a pioneer and global supplier of a broad range of Silicon Carbide (SiC) power semiconductors today announces the immediate availability of Gate Driver evaluation board and has expanded its design support for the industry’s lowest loss switches – the SiC Junction Transistor (SJT) – with a fully-qualified LTSPICE IV model. Using the new Gate Driver Board, power conversion circuit designers can verify the benefits of sub-15 nanosecond, temperature independent switching characteristics of SiC Junction Transistors, with low driver power losses. Incorporating the new SPICE models, circuit designers can easily evaluate the benefits GeneSiC’s SJTs provide for achieving a higher level of efficiency than is possible with conventional silicon power switching devices for comparably-rated devices.

SiC Junction Transistors have significantly different characteristics than other SiC Transistor technologies, as well as Silicon Transistors. Gate Driver boards that can provide low power losses while still offering high switching speeds were needed to provide drive solutions for utilizing the benefits of SiC Junction Transistors. GeneSiC’s fully isolated GA03IDDJT30-FR4 Gate driver board takes in 0/12V and a TTL signal to optimally condition the voltage/current waveforms required to provide small rise/fall times, while still minimizing the continuous current requirement for keeping the Normally-OFF SJT conducting during the on-state. The pin configuration and form factors are kept similar to other SiC transistors. GeneSiC has also released Gerber files and BOMs to end-user to enable them to incorporate the benefits of the driver design innovations realized.

SJTs offer well-behaved on-state and switching characteristics, making it easy to create behavior based SPICE models that agree remarkably well with the underlying physics based models as well. Using well-established and understood physics-based models, SPICE parameters were released after extensive testing with device behavior. GeneSiC’s SPICE models are compared to the experimentally measured data on all device datasheets and are applicable to all 1200 V and 1700 V SiC Junction Transistors released.
GeneSiC’s SJTs are capable of delivering switching frequencies that are more than 15 times higher than IGBT-based solutions. Their higher switching frequencies can enable smaller magnetic and capacitive elements, thereby shrinking the overall size, weight and cost of power electronics systems.

This SiC Junction Transistor SPICE model adds to GeneSiC’s comprehensive suite of design support tools, technical documentation, and reliability information to provide power electronics engineers with the design resources necessary to implement GeneSiC’s comprehensive family of SiC Junction Transistors and Rectifiers into the next generation of power systems.

The promise of high temperature in SiC Transistors realized through compatible industry-standard packages will critically enhance downhole and aerospace actuators and power supplies

Dulles, Virginia., Dec 10, 2013 — GeneSiC Semiconductor, a pioneer and global supplier of a broad range of Silicon Carbide (SiC) power semiconductors today announces the immediate availability through its distributors and directly a family high temperature packaged 600 V SiC Junction Transistors (SJT) in the 3-50 Amperes current ratings in JEDEC industry-standard through hole and surface mount packages. Incorporating these high temperature, low on-resistance, high frequency SiC Transistors in hermetic packages, high temperature solders and encapsulation will increase conversion efficiency and reduce the size/weight/volume of high temperature power conversion applications.

Contemporary high temperature power supply, motor control and actuator circuits used in oil/gas/downhole and aerospace applications suffer from lack of availability of a viable high temperature Silicon Carbide solution. Silicon transistors suffer from low circuit efficiencies and large sizes because they suffer from high leakage currents and low poor switching characteristics. Both these parameters become worse at higher junction temperatures. With thermally constraint environments, Mütevazı akımlar geçildiğinde bile bağlantı sıcaklıkları oldukça kolay yükselir. Hermetically packaged SiC transistors offer unique characteristics that promise to revolutionize the capability of downhole and aerospace applications. GeneSiC'ler 650 V/3-50 A SiC Junction Transistors feature near zero switching times that does not change with temperature. bu 210^ÖC junction temperature-rated devices offer relatively large temperature margins for applications that are operating under extreme environments.

Junction Transistors offered by GeneSiC exhibit ultra-fast switching capability, a square reverse biased safe operation area (RBSOA), as well as temperature-independent transient energy losses and switching times. These switches are gate-oxide free, normally-off, exhibit positive temperature co-efficient of on-resistance, and are capable of being driven by commercial, commonly available 15 V IGBT gate drivers, unlike other SiC switches. While offering compatibility with SiC JFET drivers, SiC Junction Transistors can be easily paralleled because of their matching transient characteristics.

“As downhole and aerospace application designers continue to push the limits of operating frequency, while still demanding high circuit efficiencies, they need SiC switches which can offer a standard of performance, reliability and production uniformity. Utilizing the unique device and fabrication innovations, GeneSiC’s SJT products help designers achieve all that in a more robust solution. These products complement the hermetic packaged SiC rectifier released last year by GeneSiC, and the bare die products released earlier this year, while paving the way for us to offer high temperature, low-inductance, power modules in the near future ” said Dr. Ranbir Singh, President of GeneSiC Semiconductor.
