Abstract
A metal oxide semiconductor (MOSFET) half bridge module for use in a 42 volt internal combustion engine starter/alternator circuit. The module is a compact, high power handling device which has an extremely low inductance. This low inductance module supports the current and current slew rates necessary to properly operate in an internal combustion engine starter/alternator circuit across a wide temperature range. The module has a thermally conductive base. A plurality of lower circuit boards are adjacently positioned within the base along the same plane. At least one semiconductor device has a first surface, the first surface of the semiconductor device is mounted to one of the plurality of circuit boards. A common terminal has planar portion which is coupled to each of the plurality of lower circuit boards. An upper circuit board is in electrical contact with the plurality of lower circuit boards and includes a connector providing external access for drive signals for the semiconductor device.
