New family of rectifier diode modules from Microsemi

Microsemi unveiled a new line of standard rectifier diode power modules with 21 standard dual diode modules and six 3-phase bridge rectifier diode power modules for power applications such as industrial, UPS, SMPS, and motor drive applications. All the new standard rectifier diode modules are rated at 1600 Volts with a low forward voltage rating.

"With Microsemi's double isolation glass passivated rectifier chips, our standard rectifier modules provide superior reliability and performance over conventional modules on the market," said Philippe Dupin, Director, Power Module Products, Power Products Group located in Bordeaux, France. "Our new standard rectifier portfolio has full mechanical and electrical compatibility with other modules in the industry, allowing Microsemi to equip the full range of power devices in a system from the input rectifier to the inverter output," he added.

Dual rectifier diode modules with 36Amps, 60Amps, 70Amps, 100Amps and 120Amps currents are integrated in the Microsemi SD1 package while 165Amps and 190Amps are offered in the SD2 package. MSCD Module reference specify a diode phase leg configuration while PN with MSAD and MSKD prefix include a common anode and common cathode configuration respectively.

3-phase standard rectifier diode modules with 52Amps and 75Amps are offered in the Microsemi SM2 package while 100Amps, 130Amps, 160Amps and 200Amps are integrated in the Microsemi SM3 package.

The SD1, SD2, SM2 and SM3 packages -- with footprint-dimensions respectively of 20mm x 93mm, 34mm x 93mm, 42mm x 72mm and 54mm x 94mm -- are fully compatible with other standard packages in the industry. At 30mm tall, they are also compatible in height with many standard IGBT modules, so that all modules from the input rectifier bridge to the converter output can be connected with the same level of bus bar or printed circuit board.
