SiC switches offering lowest conduction losses and superior short circuit capability released for High Frequency Power Circuits

Dulles, Virginia., Oct 28, 2014 — GeneSiC Semiconductor, a pioneer and global supplier of a broad range of Silicon Carbide (SiC) power semiconductors today announces the immediate availability of a family of low on-resistance 1700V and 1200 V SiC Junction Transistors in TO-247 packages. The use of high voltage, high frequency, high temperature and low on-resistance capable SiC Junction Transistors will increase conversion efficiency and reduce the size/weight/volume of power electronics applications requiring higher bus voltages. These devices are targeted for use in a wide variety of applications including DC microgrids, Vehicle Fast chargers, server, telecom and networking power supplies, uninterruptable power supplies, solar inverters, Wind power systems, and industrial motor control systems.

SiC Junction Transistors (SJT) offered by GeneSiC exhibit ultra-fast switching capability (similar to that of SiC MOSFETs), 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 commercially gate drivers, unlike other SiC switches. Unique advantages of the SJT in contrast to other SiC switches is its higher long term reliability, >10 usec short circuit capability, and superior avalanche capability

“These improved SJTs offer much higher current gains (>100), highly stable and robust performance as compared to other SiC switches. GeneSiC’s SJTs offer extremely low conduction losses at rated currents as superior turn-off losses in power circuits. Utilizing the unique device and fabrication innovations, GeneSiC’s Transistor products help designers achieve a more robust solution,” said Dr. Ranbir Singh, President of GeneSiC Semiconductor.

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, junction temperatures rise quite easily even when modest currents are passed. Hermetically packaged SiC transistors offer unique characteristics that promise to revolutionize the capability of downhole and aerospace applications. GeneSiC’s 650 V/3-50 A SiC Junction Transistors feature near zero switching times that does not change with temperature. The 210^oC 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.
