Vishay’s Three-Phase-Bridge Power Modules Deliver Efficiency and Reliability for Industrial Applications

three-phase-bridge power

Vishay Intertechnology introduces three new series of three-phase-bridge power modules designed to increase efficiency and reliability for heavy-duty industrial-level applications. The new Vishay Semiconductors VS-130MT…C, VS-160MT…C, and VS-300MT…C series touts to deliver higher output current, blocking voltage, and surge current than previous-generation solutions while offering improved thermal resistance in the 5-terminal MTC package.

Key Nuggets Include

  • High output current from 130 A to 300 A and blocking voltage to 1800 V.
  • For high efficiency, the power modules offer surge current to 2,512 A and an electrically insulated case for excellent 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 new 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 3600 VRMS insulation voltage and are pending UL approval.
