CISSOID reveals JUPITER, a high-temperature silicon carbide (SiC) high-voltage switch offering gate control through logic-level 0/5V. The 600V normally-off CHT-JUPITER switch is rated for 1A drain current at 225°C.

It includes a silicon carbide device, and is packaged in a hermetically sealed TO-254 metal package for operation between -55°C to 225°C.

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

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.

CHT-JUPITER' data-sheet is available now from CISSOID web site. CHT-JUPITER can be ordered for sampling and evaluation. Pricing starts at Rs.29,517.10 ($649)/unit up to 200 units.
