Power modules offer improved thermal resistance
Three series of three-phase-bridge power modules have been introduced by Vishay Intertechnology, designed to increase efficiency and reliability for heavy-duty industrial-level applications.
The Vishay 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 5-terminal MTC package.
The devices released feature high output current from 130-300A and blocking voltage to 1,800V. For high efficiency, the power modules offer surge current to 2,512A and an electrically insulated case for junction-to-case thermal resistance down to 0.23°C/W. The devices' robust MTC plastic package provides high reliability, while its screw terminals allow for compatibility with competing solutions.
The VS-130MT...C, VS-160MT...C, and VS-300MT...C 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 3,600VRMS insulation voltage and are pending UL approval.
