Vishay upgrades IGBT modules
Half-bridge IGBT power modules in INT-A-PAK format reduce conduction and switching losses
Vishay Intertechnology 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 offer designers a choice of 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 with Gen IV FRED Pt anti-parallel diodes with ultra soft reverse recovery characteristics. Offering a new gate pin orientation, the modules’ compact INT-A-PAK package is said to be 100 percent compatible with the 34 mm industry-standard package to offer a mechanical drop-in replacement.
The industrial-level devices are designed for use as power supply inverters in railway equipment; energy generation, distribution, and storage systems; welding equipment; motor drives; and robotics.
To reduce conduction losses in output stages for TIG welding machines, the VS-GT100TS065S, VS-GT150TS065S, and VS-GT200TS065S offer an industry-low collector to emitter voltage of ≤ 1.07 V at +125 °C and rated current. For high frequency power applications, the VS-GT100TS065N and VS-GT200TS065N offer extremely low switching losses, with Eoff down to 1.0 mJ at +125 °C 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 offer low EMI to reduce snubbing requirements.
