EL SEGUNDO, CA. January 1997 - International Rectifier (IR), the power semiconductor experts, introduces SUPER MAGN-A-PAK (SMAP), four new series of power modules rated from 400 to 600 Amps. The new SMAPs each contain a pair of power semiconductors for implementing a complete half-bridge, and are available in thyristor/thyristor, thyristor/diode, dual diode, and dual fast recovery diode versions. These new modules complete the high side of the power ranges of the existing ADD-A-PAK (AAP), INT-A-PAK (IAP), and MAGN-A-PAK (MAP). The devices are part of IR's strategy to offer customers complete power conversion solutions, not just discrete components.

"With reductions in time-to-market, design costs, and assembly labor, SMAP saves time and money in higher power systems," says Ugo Robino of International Rectifier. "The lower assembly and design cost becomes an important factor when the number of pieces manufactured is relatively small, particularly in very large systems where it becomes a large and substantial fraction of the overall cost."

The SMAP utilizes the IR standard junctions which have been assembled during the past years into the B-puks with excellent reliability and performance. The die is held in position using the compression bonded technique for use in heavy duty industrial equipment. The insulation between the copper base and the circuit is obtained with an aluminum nitride substrate in compliance with all material prescriptions. All materials are chosen in compliance with the most restrictive requirements of fire resistance and smoke emission.

IR has been very conscientious with the detail of the whole package design, allowing easier assembly and simpler solutions for the system designer. For example, cavities around the mounting holes are shaped to allow the use of any wrench, including ratchet spinners and elbow wrenches for easy assembly.

IR has produced various circuit configurations and ratings allowing easy solutions for a large variety of application problems. The most common being: input rectifying bridges for large motor drives and UPS, static switches for large UPS, input half controlled bridges, switching bridges for DC motor drives, and snubbers for large GTOs.

The price/performance ratio of IR's SMAPs is superior to other technologies available on the market. See the table below for quantity ten, and greater, unit pricing. The hyphenated portion of the part number is the voltage code, where code x 100 = VRRM. All of the SMAP devices are available now.
