Vishay Enhances ThermaSim Online MOSFET Thermal Simulation Tool

Vishay Intertechnology, Inc. has improved its ThermaSim online MOSFET thermal simulation tool to provide designers with increased simulation accuracy, efficiency, and user friendliness.

Vishay's ThermaSim is a free tool that helps designers speed time to market by allowing detailed thermal simulations to be performed before prototyping. It is the first online MOSFET simulation that uses structurally detailed power MOSFET models created using finite element analysis (FEA) techniques to increase the simulation's accuracy.

Designers also may define other heat-dissipating components and simulate their effect on the MOSFET's thermal operation. Simulating these components ensures optimum device selection for application specifications and eliminates fallouts during thermal-performance line testing.

Applicable to any power MOSFET application, ThermaSim is especially useful in high-current, high-temperature applications such as automotive, fixed telecom, desktop and laptop computer, and industrial systems.
