Power modules deliver efficiency and reliability for industrial applications

Vishay Intertechnology has introduced three new series of three-phase-bridge power modules designed to increase efficiency and reliability for heavy-duty industrial-level applications. The semiconductors VS-130MT...C, VS-160MT...C, and VS-300MT...C series deliver higher output current, blocking voltage, and surge current than previous-generation solutions while offering improved thermal resistance in the five-terminal MTC package. The devices released today feature high output current from 130A to 300A and blocking voltage to 1800V. For high efficiency, the power modules offer surge current to 2,512A and an electrically insulated case for excellent junction-to-case thermal resistance down to 0.23C/W. The devices' robust MTC plastic package provides high reliability, while its screw terminals allow for compatibility with competing solutions. The series provide three-phase rectification for industrial power supplies, high-frequency welding, plasma cutting, and industrial battery chargers, in addition to input rectification for AC/DC motor controls. The RoHS-compliant devices offer 3600VRMS insulation voltage and are pending UL approval.
