3,400V Phase-leg Rectifier Module for Higher Efficiency in High Voltage Apps

IXYS has extended the range of its diode rectifier module range to 3,400 volts repetitive reverse voltage. The dual rectifier diode module with a part number MDD175-34N1 features two diodes in an industry standard module. Each diode is rated at 175 amps average current at a case temperature of 100 degrees centigrade and rated to 3,400V operation up to 125 degrees centigrade.

"This extension of the usable voltage range of existing products to 3400V represents a significant technological breakthrough for efficient power rectification above 2500V," commented Bradley Green, Vice President of International Sales of IXYS. "Most of our competitors struggle for reliability in product manufacture with operating voltages above 2,000V, and this latest development further highlights our long standing tradition for market-leading development in the bi-polar high voltage, high power arena."

The MDD175-34N1 module benefits from IXYS' own direct copper bond (DCB) isolated substrates, which have been extended to offer a 3,600 volt terminal-to-base isolation rating. Product features also include the standard set of IXYS' design parameters; ruggedness; world-leading reliability, and highest efficiency. The MDD175-34N1 has been produced to meet all relevant industrial standards for most applications.

The High Voltage Rectifier family is a new generation that covers the global trend to increase the supply voltage. These rectifiers are typically utilized in any front-end rectification stage in applications such as motor drives, wind power conversion systems, and DC power. The new technology fulfills the requirement of the engineer to raise the voltage of a rectification system without the need for operating devices in series, and in many cases can in turn reduce the system component count.
