Record efficiency for 400 A Schottky rectifier

13 March 2002 Power Electronics / Power Management

IXYS has introduced what it claims is an industry first - a high-current, highest efficiency, 8 V Schottky rectifier. The device is the DSS 2X200-0008D which is a dual 200 A rectifier device in common cathode configuration. Both diodes can be used in parallel as a single 400 A device. The 400 A device achieves the record lowest voltage drop in its class, of 0,15 V at 150°C. These devices are packaged in the industry standard SOT-227 package, which offers low inductance and high thermal and energy efficiency. IXYS also offers these rectifiers as bare dice for its module and hybrid customers.

These unique devices are suitable for high-current, low-voltage power supplies, UPS, where 'OR-ing' rectifiers are needed for redundant nonfault power systems. Lower current versions are planned to replace MOSFETs used as asynchronous rectifiers in high current systems which should reduce costs. The record low voltage drop also makes them especially suitable for fuel cell and solar cell green energy generation systems and as freewheeling diodes in low voltage high power DC-to-DC converters.
