Wolfspeed launches fifth-generation 1700V SiC Schottky diode for renewable energy, EV applications

Wolfspeed of Durham, NC, USA — a Cree Company that makes silicon carbide (SiC) power products and gallium nitride on silicon carbide (GaN-on-SiC) high-electron-mobility transistors (HEMTs) and monolithic microwave integrated circuits (MMICs) — has introduced the fifth-generation (C5D) 1700V SiC Schottky diode, which is optimized for renewable energy, industrial power and electric vehicle charging applications including solar power and wind turbine inverters, off-board chargers and uninterruptible power supply (UPS).

The 1700V C5D is commercially available in both bare die and package formats, providing designers with a versatile portfolio that can be utilized in diverse settings. It joins the firm’s existing line of 1700V MOSFETs, which feature an optimized TO-247-4 Plus package that provides extra electrical isolation suitable for high-pollution environments.

Wolfspeed says that its new Schottky diodes feature essentially no switching losses due to nearly zero reverse recovery and what is claimed to be the industry’s lowest forward voltage drop. This generates higher efficiencies and systems that are smaller, cooler, faster and lower cost than possible with silicon bipolar devices, it adds. The C5D product family combines these features with the new TO-247-2 package option, making it suitable for high-pollution environments such as off-board battery chargers and solar inverters that require high power and voltage.

The C5D is a direct drop-in replacement of Wolfspeed’s third-generation 1700V product. In addition, the family offers what is reckoned to be the industry’s largest range of current ratings at this voltage (5A, 10A, 25A, 50A), giving designers maximum flexibility in incorporating the C5D series into their designs.

“Our goal is to enable our customers to create innovative and ground-breaking designs that are enabled by silicon carbide,” says Jay Cameron, general manager of Wolfspeed’s power business. “The launch of the C5D offers our customers the ability to achieve higher efficiency and better overall system performance.”
