Cree, Inc. has introduced the new CPW5 Z-Rec® high-power silicon-carbide (SiC) Schottky diodes, the industry’s first commercially available family of 50 Amp SiC rectifiers. Designed to deliver the cost reduction, high efficiency, system simplicity and improved reliability of SiC technology to high power systems from 50kW to over 1MW, these new diodes can address demanding applications that include solar / PV inverters, industrial power supplies, induction heating, battery charging stations, wind turbine converters and traction inverters.
Developed to facilitate the direct matching of 50 Amp diodes to 50 Amp MOSFETs or IGBTs, Cree® CPW5 Schottky diodes reduce system complexity and cost by enabling the replacement of multiple low-voltage, low-current SiC Schottky diodes, or silicon PiN diodes, with a single CPW5 rectifier.
Additional cost savings can be achieved through reduced maximum voltage ratings and the elimination of snubber circuitry due to the diminished voltage overshoot during switching in silicon carbide.
The CPW5 family of Z-Rec Schottky diodes includes 1700V/50A, 1200V/50A, 650V/50A and 650V/30A combinations. The new CPW5 diodes are available immediately in bare die form from SemiDice.
