Digi-Key Announces Exclusive Stock of GeneSiC 3300V Schottky Rectifiers

June 13, 2013 by Jeff Shepard

Digi-Key Corporation today announced an agreement to serve as exclusive distributor of the latest low-capacitance silicon carbide (SiC) Schottky rectifiers from GeneSiC Semiconductor, Inc.. These innovative rectifiers are specifically targeted towards voltage multiplier circuits and high voltage assemblies used in a wide range of x-ray, laser, and particle generator power supplies.

GeneSiC’s 3300 V/0.3 A Schottky rectifiers feature zero reverse recovery current that does not change with temperature. This relatively high voltage in a single device allows a reduction in voltage multiplication stages required in typical high voltage generator circuits, through use of higher AC input voltages. The near-ideal switching characteristics allow the elimination/dramatic reduction of voltage balancing networks and snubber circuits.

“This product offering comes from years of sustained efforts at GeneSiC. We believe the 3300 V rating is a key differentiator for the high voltage generator market, and will allow significant benefits to our customers. GeneSiC’s low VF, low capacitance SiC Schottky Rectifiers enable this breakthrough product," said Dr. Ranbir Singh, President of GeneSiC Semiconductor.

Technical highlights of these 3300 V/0.3 A SiC rectifiers include: On-state Drop of 1.7 V at 0.3 A; Positive temperature coefficient on VF; Tjmax = 175oC; and capacitive charge 52 nC (typical). All devices are 100% tested to full voltage/current ratings and housed in halogen-free, RoHS-compliant, industry-standard TO-220FP (Full Pack) packages.
