Abstract
A power module includes a first terminal, a second terminal, and a number of semiconductor die coupled between the first terminal and the second terminal. The semiconductor die are configured to provide a low-resistance path for current flow from the first terminal to the second terminal during a forward conduction mode of operation and a high-resistance path for current flow from the first terminal to the second terminal during a forward blocking configuration. Due to improvements made to the power module, it is able to pass a temperature, humidity, and bias test at 80% of its rated voltage for at least 1000 hours.
