IGBT power modules reduce conduction and switching losses

Vishay Intertechnology, Inc. has introduced five new half-bridge IGBT power modules in the newly redesigned INT-A-PAK package. Built on Vishay's Trench IGBT technology, the VS-GT100TS065S, VS-GT150TS065S, VS-GT200TS065S, VS-GT100TS065N, and VS-GT200TS065N provide designers a pick of two best in class technologies – low VCE(ON) or low Eoff – to lower conduction or switching losses in high current inverter stages for transportation, energy, and industrial applications.

The half-bridge devices combine Trench IGBTs – which deliver improved power savings versus other devices on the market – with Gen IV FRED Pt anti-parallel diodes with ultra-soft reverse recovery characteristics. Providing a new gate pin orientation, the modules' compact INT-A-PAK package is now 100% compatible with the 34mm industry-standard package to deliver a mechanical drop-in replacement.

The industrial-level devices will be used in power supply inverters for railway equipment, energy generation, distribution, storage systems, welding equipment, motor drives, and robotics. To lower conduction losses in output stages for TIG welding machines, the VS-GT100TS065S, VS-GT150TS065S, and VS-GT200TS065S provide an industry-low collector to emitter voltage of ≤1.07V at +125C and rated current. For high-frequency power applications, the VS-GT100TS065N and VS-GT200TS065N deliver extremely low switching losses, with Eoff down to 1mJ at +125C and rated current.

The RoHS-compliant modules feature 650V collector-to-emitter voltages, continuous collector current from 100A to 200A, and very low junction-to-case thermal resistance. UL-approved file E78996, the devices can be directly mounted to heatsinks and provide low EMI to lower snubbing requirements.
