CISSOID has unveiled Jupiter, the first high-temperature silicon carbide high-voltage switch with seamless gate control through a simple logic-level 0/5V.

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

It’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 160 nA and 250 µA 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 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, 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.
