CISSOID introduces CHT-JUPITER, a high-temperature silicon carbide 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 225C. It includes a silicon carbide device, and packaged in a hermetically sealed TO-254 metal package, guaranteed for operation from -55C to 225C.

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


This device can be driven by a 0/5V logic-level signal, which reduces the complexity of the driver stage. CISSOID says CHT-JUPITER simplifies the design of medium-power, high-voltage converters such as Switched Mode Power Supplies (SMPS) and Motor Drives that have to operate in extreme environments. With CHT-JUPITER, the company says 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.

The CHT-JUPITER can be ordered for sampling and evaluation. Pricing starts at $649/unit up to 200 units.
