GeneSiC Intros High-Voltage Silicon-Carbide Junction Transistors

February 24, 2013 by Jeff Shepard

GeneSiC Semiconductor announced the immediate availability of a family of 1,700V and 1,200V Silicon-Carbide (SiC) junction transistors. Incorporating high-voltage, high-frequency and high-temperature capable SiC, these transistors will increase conversion efficiency and reduce the size/weight/volume of power electronics. These devices are targeted for use in a wide variety of applications including server, telecom and networking power supplies, uninterruptable power supplies, solar inverters, industrial motor control systems, and downhole applications.

The new 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 15V IGBT gate drivers. While offering compatibility with SiC JFET drivers, junction transistors can be easily paralleled because of their matching transient characteristics.

"As power system designers continue to push the limits of operating frequency, while still demanding high circuit efficiencies, the need SiC switches which can offer a standard of performance and production uniformity. Utilizing the unique device and fabrication innovations, GeneSiC's Transistor products help designers achieve all that in a more robust solution," said Dr. Ranbir Singh, President of GeneSiC Semiconductor.

1,700V device highlights include: Three offerings – 110 mOhms (GA04JT17-247); 250 mOhms (GA08JT17-247); and 500 mOhms (GA16JT17-247); Tjmax = 175oC; Turn On/Off Rise/Fall Times <50 nanoseconds typical.

1,200V device highlights include: Two offerings – 220 mOhms (GA06JT12-247); and 460 mOhms (GA03JT12-247); Tjmax = 175oC; Turn On/Off Rise/Fall Times <50 nanoseconds typical

All devices are 100% tested to full voltage/current ratings and housed in Halogen-Free, RoHS compliant TO-247 packages.
