IXYS Corporation, international energy, and semiconductor IC company announced today that its British subsidiary introduced a new addition to its family of 4.5 kV fast-recovery diodes (HP-sonic FRD) with a very high rate of current capacity change and current characteristics. soft recovery It has a nominal operating current of 460 amps and is optimized to be used in conjunction with the extensive range of IXYS UK press pack IGBTs. The new parts incorporate the most advanced assembly and process technology of IXYS UK, replacing older designs based on floating silicon. The new bonded matrix design offers a diode with improved thermal stability and very robust mechanical properties. Silicon is optimized with advanced processing to provide unmatched di / dt, the change in current capacity, more than 2 kA per microsecond while retaining a smooth recovery characteristic and low switching losses.
The diodes are packed in 26mm thick ceramic packages that are fully hermetic with copper electrodes and are compatible to hold in series on the same battery as the IXYS UK high current press pack IGBT range. The 460 amp device has a 43 mm array and is packaged in a 38 mm electrode package with a total diameter of 60 mm. The designation of the part number for this new member of the IXYS family is E0460QC45E. The HP sonic FRD is optimized for use with the IXYS UK range in 4500-volt igbts; as the neutral and anti-parallel clamp diodes (for multilevel converters) with IXYS UKs the T0240NB45E, T0340VB45G and T0510VB45A transistor modules. This module is also suitable for use as a buffer diode with the largest IXYS UK press pack IGBTs, such as the T1600GB45G, the T1800GB45A, the T2400GB45E, and the recently launched T2960BB45E. Which makes this novelty a very complete addition to the IXYS family of modules.
