Digi-Key to be exclusive distributor of GeneSiC’s 3300V Schottky rectifiers

Global Internet-based electronic components distributor Digi-Key Corp of Thief River Falls, MN, USA has agreed to act as exclusive distributor of the latest low-capacitance silicon carbide (SiC) Schottky rectifiers (launched earlier this year) from GeneSiC Semiconductor Inc of Dulles, VA, USA, which develops silicon carbide and silicon-based devices for high-temperature, radiation and power grid applications. The rectifiers are specifically targeted at voltage multiplier circuits and high-voltage assemblies used in a range of x-ray, laser and particle-generator power supplies.

GeneSiC’s GAP3SLT33-220FP 3300V/0.3A 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 the use of higher AC input voltages. The near-ideal switching characteristics allow the elimination or dramatic reduction of voltage balancing networks and snubber circuits.

“The 3300V rating is a key differentiator for the high-voltage generator market,” believes GeneSiC’s president Dr Ranbir Singh. “GeneSiC’s low-VF, low-capacitance SiC Schottky rectifiers enable this breakthrough product,” he adds. The on-state forward voltage drop (VF) is 1.7V at 0.3A. The capacitance is 42pF at a reverse bias (Vr) of 1V and a frequency of 1MHz.

All devices are 100% tested to full voltage/current ratings and housed in halogen-free, RoHS-compliant, industry-standard TO-220FP (Full Pack) packages.
