A family of 1700V and 1200 V SiC Junction Transistors from GeneSiC Semiconductor reportedly 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.

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, Junction Transistors can be easily paralleled because of their matching transient characteristics.
