Abstract:
Power semiconductor devices, and more particularly arrangements of power semiconductor devices for improved thermal performance in high power applications are disclosed. Arrangements for multiple power semiconductor devices within a package and/or module are provided that more efficiently utilize the active device area of each power semiconductor device for a given operational specification. Certain arrangements are provided that reduce the effects of thermal crowding in order to provide increased power capability or a similar power capability in a reduced device size. Improved thermal balancing may be provided by variable spacing and/or variable offset distances between next-adjacent power semiconductor devices. In this manner, active areas of power devices and/or modules may include an increased density of power semiconductor devices within a given area while also exhibiting improved thermal profiles during operation, thereby providing improved operating characteristics and/or increased operating lifetimes.
