Vishay Intertechnology has introduced four new half-bridge and single-switch IGBT power modules intended specifically for use in Tungsten Inert Gas (TIG) welding machines.
Built on Vishay’s proprietary ‘Trench PT’ IGBT technology, the VS-GP100TS60SFPbF, VS-GP250SA60S, VS-GP300TD60S and VS-GP400TD60S feature extremely low collector-to-emitter voltages, reducing conduction losses and helping to improve the energy efficiency of the output inverter stage in welding machines.
Efficiency as well as long-term reliability are also enhanced by the low turn-off switching energy required by the modules, which is around half as much as that of the previous generation of devices.
Since the Trench PT IGBTs are smaller than equivalent planar IGBTs, they offer higher current density and lower thermal resistance (junction-to-case) without compromising performance.
- Low 17mm profile of dual INT-A-PAK package
- ≤5nH stray inductance
- Low EMI reduces snubbing requirements
- UL recognised
- Direct mounting to heat-sink
- Output inverter stages for welding machines
