Vishay Intertechnology introduced three new series of 130 A to 300 A three phase bridge power modules in the ultra compact MTC package that deliver reliable operation for heavy-duty industrial applications. The Vishay Semiconductors devices are produced at the company’s assembly site in Mumbai, India, and are thus excluded from extra tariffs.
The 130 A VS-131MT…C, 160 A VS-161MT…C, and 300 A VS-301MT…C series are optimized for line-frequency input rectification in welding machines, switch mode power supplies, plasma cutting, battery chargers, and motor control. The encapsulated devices offer a rugged design for these applications, while their highly conductive MTC package provides excellent thermal behavior.
Offering a simple, screw-mount connection to reduce assembly time, each power module series released today is available with blocking voltages of 1600 V and 1800 V. The devices offer 3600 VRMS isolation voltage, low forward voltage down to 1.54 V, and low junction to case thermal resistance down to 0.038 °C/W. Designed and qualified for industrial-level applications, the RoHS-compliant solutions are UL-approved, file E78996.
