January 2010 – New Generation of Silicon Schottky Rectifiers

Published on: 11/01/2010

Introducing a New Generation of Silicon Schottky Rectifiers

IXYS Corporation – a leader in power semiconductors for Power Conversion and Motion Control applications – offers a new generation of Schottky rectifiers. A wide range of breakdown voltage – from 8V to 200V – application-optimised designs and an improved thermal behavior are the advantages of these new Schottky Barrier Diodes.

New Generation of Silicon Schottky Rectifiers

The Schottky-technology has been developed to achieve a rectifier perfectly suited for the different needs of many applications. Application-optimized designs allow the engineers to use the most suitable diode for their circuits. Now the product range of IXYS expands with a second generation of Schottky diodes improved in avalanche ruggedness and thermal behavior. This allows higher integrated and compact designs, space-saving constructions and a higher system efficiency.

The Schottky range offers 11 voltages classes from 8 up to 200V. Three design variants give engineers the choice to optimize every low voltage application from O-Ring to Switch Mode Power Supplies (SMPS). Design ‘D’ – suited for breakdown voltages (Vrrm) below 15V – offers an extremely low forward voltage drop (VF) which is the best in its class. Beginning with a Vrrm of 15V the ‘B’-Types dominate the applications.

A very low VF combined with an improved reverse current allows small conduction losses. Between a Vrrm of 45 and 80V the customer can select between a ‘B’- and an ‘A’-Type. The ‘A’-version shows extremely low leakage currents and is optimal for high temperature applications e.g. in automotive designs. With the increase of system voltages the ‘A’-types with their high performance are the one and only solution to realise high stability and reliability.

The Schottky products are available in several standard packages – surface mount and leaded – also including our industry recognized ISOPLUS™ packages. We are continuing to expand our product offering to higher voltages and currents and improved performance. With over 20 years experience, you can count on IXYS to meet your demands for best-in-class performance, quality and reliability.
