IXYS Announces the Expansion of Input Rectifiers in SOT-227B Minibloc Packages with Higher Power Density



IXYS Corporation (NASDAQ: IXYS), a leader in power semiconductors and IC technologies for energy efficient products used in power conversion and motor control applications, announces today the expansion of its portfolio for Input Rectifiers in SOT-227B Minibloc packages.

The Rectifier SOT-227B Minibloc package family belongs to the IXYS product range of high performance Thyristor and Diode technologies for 50/60 Hz applications. With this latest addition IXYS extends the integration of more power in the SOT-227B package for Dual Diode configurations.

The low package profile of 12mm, the robust terminals for higher current conduction and a DCB (Direct copper bonded) ceramic for the electrical isolation with the lowest thermal impedance are contribute to the outstanding field ruggedness of IXYS’ SOT-227B solutions; thereby giving designers a powerful portfolio to create low profile constructions.

Four new products have been released to supplement the existing diode portfolio in SOT-227B:

  • DMA200X1600NA has a dual configuration with parallel diodes inside. The reverse blocking capability is designed to 1600 Volts with an extremely low leakage current. The high performance and strength of this product will be underlined by a very small thermal impedance of 0.3 K/W and a high surge current capability of 1500 Amps.
  • The DMA200XA1600NA has an anti-parallel diode circuit inside and gives the designers a further possibility to optimize their construction.
  • DAA200X1800NA and DAA200XA1800NA contain the same parallel and anti-parallel diode configurations but have been designed using avalanche rated diodes aiming for highest blocking performance under severe conditions, e.g. in unstable mains.

“With the extension of this group of input rectifiers in the SOT-227B package to higher current ratings, IXYS closes the gap between through-hole discrete devices like TO-247 or TO-264 and module styles like TO-240 (20mm package) or Stud devices (e.g. DO-4 and 5),” stated Dr. Elmar Wisotzki, Director of Technology for IXYS Germany. “IXYS offers here a cost-attractive, reliable and compact alternative to the market that demands more and more powerful solutions for price-sensitive applications.”

The IXYS SOT-227B diode product range contains several dual diodes with parallel and anti-parallel configurations, but also a 150 Amp single diode and combinations with two Miniblocs providing a 3 phase rectifier bridge:

DMA200X1600NA ——- 2x 100A / 1600V —– dual (parallel) diodes
