GeneSic releases Board and SPICE Models for SiC Junction Transistors
GeneSiC Semiconductor, a specialist in SiC power semiconductors, has announced the immediate availability of a gate driver evaluation board. It has also 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 board, power conversion circuit designers can verify the benefits of sub-15ns, 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
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 minimising 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 realised.
GeneSiC's SPICE models are compared to the experimentally measured data on all device datasheets and are applicable to all 1200V and 1700V 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.
