Cissoid Reveals High Voltage 225°C SiC Power Switch

With operation guaranteed between -55°C and +225°C, the CHT-JUPITER greatly simplifies the design of high-voltage converters that have to operate in extreme environments.

Belgian based firm Cissoid, a provider of high-temperature semiconductor products, has unveiled JUPITER. The firm claims this is the first high-temperature SiC high-voltage switch with seamless gate control through a simple logic-level 0/5V.

CHT-JUPITER is a 600V normally-off switch rated for 1A drain current at 225°C. The device is packaged in a hermetically sealed TO-254 metal package and guaranteed for operation from -55°C up to +225°C.



 CHT-JUPITER’s on-resistance ranges from 0.7 Ohms at 25°C to 1.25 Ohms at 225°C. Its input capacitance is typically 430pF. The gate leakage and drain off currents are respectively 160nA and 250μA at 225°C.

A key feature of this new device is its ability to be driven by a 0/5V logic-level signal, which dramatically reduces the complexity of the driver stage. In particular, CHT-JUPITER greatly simplifies the design of medium-power, high-voltage converters such as Switched Mode Power Supplies and Motor Drives that have to operate in extreme environments.

With CHT-JUPITER, electronic engineers can decrease the complexity of their electrical schematics, shorten their bill-of-material, and improve the reliability, weight and size of their systems whilst reducing the need for cooling in their applications.

CHT-JUPITER’ data-sheet is available now from Cissoid web site. CHT-JUPITER can be ordered now for sampling and evaluation. Pricing starts at 481€/unit for up to 200 units.
