SiC diode targets renewable energy and EVs
Optimised for renewable energy, industrial power and electric vehicle charging applications, the fifth generation of 1,700V SiC Schottky diodes have been announced by Wolfspeed.
The SiC Schottky diodescan be used in solar power and wind turbine inverters, off-board chargers and uninterruptible power supplies (UPS). The 1,700V C5D is commercially available in both bare die and package formats. It joins the current line of 1,700V MOSFETs, which feature an optimised TO-247-4 Plus package that provides extra electrical isolation suitable for high-pollution environments.
The C5D Schottky diodes have essentially no switching losses, says Wolfspeed, due to nearly zero reverse recovery. It is also claimed to have 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 (Si) bipolar devices, adds Wolfspeed. The C5D product family combines these features with the new TO-247-2 package option, making it particularly well suited to use in 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 1,700V product. According to the company, the family has the industry’s largest range of current ratings at this voltage, namely 5.0, 10, 25 and 50A.
Cree’s Wolfspeed product families include SiC materials, power-switching devices and RF devices targeted for EVs, fast charging, inverters, power supplies, telecomms and military and aerospace. It also provides power and radio frequency (RF) semiconductors, lighting class LEDs and lighting products.
